UGREEN DH2300 NAS Review – Design and Storage

The UGREEN DH2300 adopts a clean, vertical form factor made entirely of plastic, emphasizing practicality and low cost over premium materials. The enclosure is lightweight yet well-ventilated, featuring a magnetic plastic top panel with slotted air channels that promote consistent airflow across both drive bays. The overall construction favors simplicity, with drive access positioned vertically rather than through traditional caddies. This layout helps minimize the unit’s footprint, making it suitable for desktop environments where noise and vibration are key considerations. While the plastic frame lacks the rigidity of aluminum enclosures seen in higher-end NAS models, it contributes to lower noise resonance and reduced amplification of mechanical drive vibration. The minimalist aesthetic, consistent with UGREEN’s other recent NAS releases, reflects its target audience: users seeking a consumer-friendly device that blends into a home office or living space rather than a server rack.

Internally, the DH2300 supports two 3.5-inch or 2.5-inch SATA drives, each connecting directly to fixed SATA connectors mounted on the board. The drive trays are basic but functional, requiring manual screw installation rather than tool-less mechanisms. Although UGREEN has not explicitly advertised hot-swapping as an official feature, testing showed that it is technically possible to replace drives without powering down, though such actions are not recommended without confirmation from official documentation. The NAS supports standard RAID configurations, including JBOD, RAID 0, and RAID 1, as well as individual drive modes, providing adequate flexibility for redundancy or performance-based setups. Storage initialization is straightforward within UGOS, with pool creation and volume setup guided by a wizard interface that fits the product’s “set-and-forget” philosophy.

Cooling is handled by a single rear-mounted fan positioned behind the drive bays, ensuring that heat generated by mechanical disks is efficiently extracted from the enclosure. The system’s vertical drive layout assists in natural convection, drawing air from the lower portion and expelling it from the top and rear. Despite being a plastic chassis, thermal management remains effective due to the extensive side and rear ventilation grilles, which circulate air across both drives and the mainboard components. In long-term use, the design demonstrated stable internal temperatures under typical file access and synchronization loads, maintaining drive and board thermals within an expected operational range even during extended testing periods.

From a functional standpoint, the DH2300 includes an internal 32GB eMMC module reserved for UGOS, preventing users from needing to dedicate part of their main storage array to system files. This separation simplifies setup and improves reliability by isolating the operating system from data drives. However, there are no M.2 or NVMe expansion slots available, meaning caching or SSD-tiered storage cannot be implemented. This is consistent with UGREEN’s entry-level positioning for the model, and the omission helps reduce production cost while keeping the power footprint low. The 32GB internal storage performs adequately for OS updates, indexing data, and temporary system operations.

The device’s storage capacity can reach up to two 30TB drives, allowing a maximum theoretical total of 60TB raw capacity, though most users will likely configure it in RAID 1 for redundancy. This makes the DH2300 a practical fit for home backup, photo archiving, and small-scale media libraries, especially when paired with the system’s built-in applications for photos, video, and document management. Overall, the DH2300’s design and storage layout reflect its goal of balancing ease of use with functional flexibility, providing just enough configurability to support typical home NAS workloads without introducing complexity that would deter less technical users.

UGREEN DH2300 NAS Review – Internal and External Hardware

Internally, the UGREEN DH2300 is powered by the Rockchip RK3576 processor, a hybrid 8-core ARM SoC that combines four high-performance Cortex-A72 cores with four efficiency-focused Cortex-A53 cores, running at up to 2.2GHz. While UGREEN markets this configuration as an “8-core processor,” it is technically composed of two separate quad-core clusters, something the company’s documentation does not clearly explain. This lack of clarity can mislead users into expecting a single unified 8-core design, whereas in practice the chip functions as two 4-core groups optimized for different workloads. The RK3576, built on an 8nm process, delivers a solid balance between efficiency and multitasking, keeping thermals low while maintaining adequate throughput for home NAS tasks. Its integrated ARM G52 MC3 GPU supports up to 8K H.265/H.264 decoding and HDR rendering through Rockchip’s dedicated Picture Quality Engine, which also supports ACM and DCI color profiles. These capabilities allow the DH2300 to output 4K60 video via HDMI, offering lightweight media playback directly from the system interface—an uncommon inclusion in this price class. Additionally, the CPU’s built-in 6 TOPS NPU enables AI-assisted indexing and face recognition within UGOS Pro, processing such tasks locally instead of relying on cloud services.

Memory allocation on the DH2300 is fixed at 4GB of LPDDR4X, soldered to the mainboard with no expansion slot available. This restriction aligns with the model’s consumer-grade purpose, though it naturally caps Docker container and multitasking potential. The onboard memory is sufficient for file serving, indexing, and moderate background services, while the 32GB eMMC 5.1 storage is dedicated to UGOS Pro and ensures stable OS operations without user intervention. There are no NVMe or UFS storage options, which simplifies the hardware layout but limits potential caching or high-speed data tiers. Nevertheless, the RK3576’s low power draw and balanced architecture ensure consistent operation under typical workloads, even during prolonged use, with minimal heat output and silent operation under idle conditions.

Externally, the NAS presents a modest selection of connectivity options suitable for its market position. The rear hosts a single 1GbE LAN port—adequate for most home users but a notable downgrade from the 2.5GbE interface found on UGREEN’s larger models like the DH4300. File transfers, backups, and streaming functions remain well within the limits of 1GbE for single-user environments, though network saturation can occur during multi-user access. Peripheral connectivity is handled by two USB-A 3.2 Gen 1 ports and one USB-C 3.2 Gen 1 port, all operating at 5Gbps, supporting external drives, UPS communication, or backup targets. An HDMI 2.0 port on the rear supports 4K60 output for local playback or display configuration, while system LEDs provide visual feedback for drive activity, system status, and network connection. Power is supplied by a 50W external adapter that connects via a barrel plug, keeping internal temperatures and noise low by externalizing the PSU.

The inclusion of HDMI output in such a budget-focused system underscores UGREEN’s attempt to merge NAS and home entertainment functions. Although the RK3576 chipset supports a wider range of display interfaces—including DisplayPort, MIPI, and eDP—these are not implemented in the DH2300’s design, reflecting deliberate simplification for cost and usability. The absence of multi-gigabit networking, PCIe expansion, or additional LAN redundancy limits its potential for advanced setups, yet for its intended audience the configuration remains practical. In short, the DH2300’s internal layout, despite its simplified design and some ambiguous marketing around the CPU, delivers an efficient and capable platform for mainstream home users seeking affordable private storage.

UGREEN DH2300 NAS Review – UGOS NAS Software and Services

UGREEN’s DH2300 runs the company’s proprietary UGOS Pro, a Linux-based operating system tailored for simplicity and everyday use. The interface mirrors the design language of mainstream consumer cloud platforms, featuring a desktop-style environment with drag-and-drop file management, live system monitoring, and user account controls. Although UGOS Pro shares much of its design and functionality with that found on UGREEN’s larger DH4300 model, a few service limitations appear due to the ARM-based architecture of the DH2300. These include the absence of virtual machine support and limited resource capacity for multiple Docker containers, stemming from the 4GB of fixed memory. Nonetheless, the software remains fully featured for file storage, synchronization, multimedia management, and light AI applications, and receives regular over-the-air updates that refine usability and security. The desktop and mobile clients also synchronize settings seamlessly, allowing users to manage their NAS both locally and remotely.

From a user management perspective, UGOS provides fine-grained control of accounts, permissions, and network access. Administrators can create user groups, apply password complexity policies, and define shared-folder privileges with ease. The system supports multiple file transfer protocols, including SMB, AFP, NFS, and Rsync, as well as optional WebDAV and FTP for broader compatibility. Remote access can be configured either through UGREEN’s own relay service or via LAN-only mode for tighter network security. The security dashboard consolidates features such as auto-block for repeated failed logins, two-factor authentication, firewall configuration, and selective port access rules. SSH and Telnet access are disabled by default, a responsible design choice for less experienced users, but can be enabled manually for advanced administration. These features bring the DH2300 close in functionality to entry-level NAS systems from Synology or QNAP, even though it remains less configurable overall.

Storage management is one of UGOS Pro’s more mature components. Users can create storage pools and volumes in JBOD, RAID 0, or RAID 1, with scheduled drive tests, SMART diagnostics, and Seagate IronWolf Health integration for supported drives. The storage manager also includes rebuild and repair settings that allow users to prioritise either RAID reconstruction speed or system performance during rebuilds. Snapshot protection is integrated at the folder level, with both versioned and scheduled snapshots available for data recovery. Although the system does not offer full OS-level backups, users can schedule NAS-to-NAS, NAS-to-USB, and NAS-to-Cloud synchronisation tasks using Rsync or proprietary tools. These backups can include filters for file type, size, and modification date, making them adaptable to both personal and small office usage. In practice, the storage controls are intuitive and well-implemented for a first-generation NAS platform, with sufficient safeguards for casual users who might otherwise rely on third-party cloud apps.

Application availability has steadily improved since UGREEN’s NAS debut in 2023 (at least, in the ‘west’, as they have been a NAS name in the east since 2020/2021). The App Center now includes a range of first-party utilities such as a file manager, photo station, video station, and music library, as well as third-party options like Plex, Jellyfin, and Docker containers. AI-based features such as face, text, and object recognition are supported thanks to the 6 TOPS NPU in the RK3576, though performance varies depending on workload size. The integrated Vault app provides encrypted storage areas secured by password or downloadable key, which can be auto-locked on reboot for privacy. Meanwhile, the mobile companion app mirrors almost every desktop function, from user and storage administration to Docker control and media playback. Having all management tasks accessible within a single unified mobile app, rather than separate applications for photos or video, demonstrates UGREEN’s streamlined approach to usability, positioning UGOS Pro as a consumer-friendly OS that hides most of the NAS complexity from first-time users. However, I cannot stress enough that this software is still a decent way behind long-established players such as Synology DSM and QNAP QTS in terms of features, maturity and client support. Additionally, as one of the newest names in the world of NAS, the brand has yet to be truly ‘tested’ when it comes to security strength and how they handle/respond to a larger scale security incident. So wheat we find here is good enough for hte price point, but is only a small step or two above what users have come to expect from privately owned NAS nonetheless in 2025/2026.

UGREEN DH2300 NAS Review – Heat, Noise and Power Consumption Tests

Thermal and acoustic performance on the UGREEN DH2300 is generally stable and consistent with expectations for a low-power ARM-based NAS. The system uses a single rear-mounted fan that automatically adjusts its RPM in response to internal temperature sensors, aided by the ventilated top and side panels. During extended operation, the fan demonstrated smooth, gradual speed transitions rather than abrupt cycling, which helped minimize background noise. With two 4TB Seagate IronWolf drives installed, the system recorded approximately 31–32 dBA in idle mode with the fan set to “Low” in UGOS. When switched to “Auto,” and under light file activity, readings rose to 33–35 dBA, while heavier read and write operations increased noise levels to 38–41 dBA. Under maximum fan speed, levels peaked at 44–45 dBA, making the fan audible but still within acceptable limits for a desktop environment. The use of plastic housing reduces the resonance that typically amplifies drive vibration in metal enclosures, although some low-frequency hum remains during heavy disk access.

Temperature readings taken over a 24-hour mixed-use test period show that the chassis maintains good internal thermal balance, aided by vertical airflow and efficient low-wattage components. The NAS was powered down overnight before the test, then reactivated for hourly upload and backup tasks, simulating intermittent real-world usage. During idle periods, the drives stabilized at 35–37°C, while moderate access cycles pushed them to 42°C. The motherboard and surrounding airflow remained at approximately 34–35°C, with rear exhaust temperatures registering slightly higher. Despite the passive nature of some cooling zones, heat accumulation around the CPU remained minimal, peaking around 50–60°C during sustained transfer activity. These figures suggest that UGREEN’s internal airflow design, while basic, is sufficient for continuous operation with standard HDDs. Users in warmer climates or those employing higher-RPM drives might consider increasing fan control sensitivity via UGOS to maintain consistent thermals.

Power consumption results were equally conservative. With two 4TB mechanical drives installed and the system idle at below 5% CPU utilization, the DH2300 drew roughly 9.5W, a competitive figure for a two-bay NAS. During typical data transfers and 50% CPU load, draw increased modestly to 12–13W, remaining far below that of comparable x86-based systems. The external 50W power adapter ensures the NAS operates efficiently while reducing internal heat buildup. Users employing SSDs instead of HDDs could expect overall consumption to drop by an additional 4–5W, further improving energy efficiency. These results confirm the DH2300’s suitability for continuous operation, including 24/7 use as a network backup target or low-impact media server.

Its minimal noise and low thermal footprint make it a non-intrusive addition to a home or small office environment, aligning with its purpose as a budget, always-on NAS solution.

UGREEN DH2300 NAS Review – Verdict and Conclusion

The UGREEN DH2300 represents a carefully positioned step in the company’s ongoing effort to make private storage approachable for non-technical users. Its hardware configuration, led by the Rockchip RK3576 processor and 4GB of fixed memory, provides solid baseline performance for a two-bay ARM-powered NAS at this price point. Although its single 1GbE network port may limit throughput for larger file transfers, the system compensates with a highly efficient power profile, quiet operation, and full support for common RAID configurations. The inclusion of a dedicated 32GB eMMC system drive, HDMI 4K60 output, and an NPU capable of AI-based photo indexing places it above most similarly priced entry-level alternatives from QNAP and Synology. However, certain aspects of UGREEN’s marketing—particularly the way the dual quad-core CPU clusters are presented as a single 8-core design—could be clearer. Likewise, the absence of upgradeable memory or faster networking options limits its long-term scalability for users seeking to expand their NAS environment beyond basic media and backup tasks.

From a broader standpoint, the DH2300’s strongest appeal lies in its simplicity and low operational overhead. UGOS Pro, though still developing in maturity, has evolved into a competent, user-friendly platform offering the key features needed for home data management, multimedia access, and scheduled backups. The OS’s stability, combined with efficient hardware and lightweight design, makes this NAS a practical alternative to annual cloud subscriptions for users who simply want local control over their data. It is not a system aimed at enthusiasts or professionals demanding virtual machines, multi-gig networking, or broad third-party OS support, but rather those seeking a self-contained, reliable, and low-maintenance device. Within that niche, the DH2300 delivers strong value and performs consistently well for the intended demographic—serving as an accessible first step into local storage ownership.

The UniFi UPS-Tower 600W UPS Review

UPDATE – The Desktop UPS TOWER is available HERE for $159 , and the 2U Rackmount UPS-2U is available later in Q4 2025 HERE for $279

UniFi’s entry into the uninterruptible power supply market brings two distinct solutions tailored for professional and prosumer environments: the UPS-Tower desktop model and the UPS-2U Rackmount unit. The tower configuration provides 1,000VA / 600W of backup capacity and uses a single 12V, 9Ah lead-acid battery, while the larger 2U rackmount version scales up to 1,440VA / 1,000W with dual battery modules. Both adopt a line-interactive architecture with simulated sine wave output, a 6–10 ms transfer time, and Ethernet-based network management. Integration is handled natively within UniFi Network, where users can adopt, monitor, and configure the UPS directly from the UniFi Controller interface. For non-UniFi deployments, both models retain NUT (Network UPS Tools) compatibility for safe shutdown and system monitoring. This marks a significant expansion of UniFi’s ecosystem into power management and continuity—areas traditionally dominated by brands like APC and CyberPower—positioning UniFi’s UPS line as a bridge between smart network infrastructure and automated power protection.

The UniFi UPS-Tower 1000VA / 600W Review – Quick Conclusion

The UniFi UPS-Tower and UPS-2U deliver practical and ecosystem-focused power protection for small network environments. Both models emphasize integration and manageability rather than raw performance, providing stable 120V line-interactive backup power with simulated sine wave output. The tower model offers 600W of protection in a compact desktop enclosure, while the rackmount unit increases capacity to 1,000W with dual batteries. Integration through the UniFi Network Controller is straightforward, enabling central monitoring and alerting without external software. While limitations such as the lack of USB ports, PoE passthrough, and pure sine wave output restrict versatility outside the UniFi ecosystem, both units are solid entries for users seeking consistent, centrally managed backup power within UniFi-managed infrastructures.

The UniFi UPS-Tower UPS Review – Design & Connectivity

The UniFi UPS-Tower adopts a vertically oriented, compact chassis that measures 288 x 99 x 280.5 mm and weighs just over 8 kg. Its enclosure is built from a polycarbonate and ABS blend, which offers a balance between durability and low weight, and the overall shape resembles a small desktop speaker or heater.

The unit’s IP20 rating indicates it is intended for indoor use only, with ventilation panels positioned at the top, sides, and bottom to maintain airflow. During testing, internal temperatures averaged around 45–47°C after 24 hours of continuous operation, demonstrating stable thermal management for a unit of this density. The design is understated, with no LCD screen or physical display, relying instead on LED indicators and the UniFi interface for monitoring battery level and status.

In terms of connectivity, UniFi has implemented a clear division between power protection and control interfaces. On the rear panel, the UPS-Tower provides five surge-only outlets and five battery-backed surge-protected outlets, all of which are NEMA 5-15R ports suitable for 120V environments. The input connection uses a NEMA 5-15P plug, rated for 12A maximum load, supporting both 50 and 60 Hz operation. While this configuration is typical of compact line-interactive UPS units, the number of protected outlets is unusually high for its size, making it suitable for powering multiple small network devices, NAS units, or edge appliances simultaneously. However, only the five battery-backed ports will remain operational during a power loss.

UniFi has also included Ethernet management for remote monitoring and control. The rear I/O layout features a 100/10 MbE network connection that links the UPS directly into the UniFi ecosystem, as well as two GbE ports for surge in/out, allowing for protection of wired data paths. This implementation enables the UPS to send automatic notifications and power-state updates to the UniFi controller, ensuring that connected devices can safely power down when mains supply is interrupted. While users will not find USB connectivity here—a feature absent from both models—Ethernet management ensures seamless network-level integration with UniFi OS devices and provides remote monitoring capabilities not typically available in basic desktop UPS designs.

On the visual and operational interface side, UniFi relies on a multi-stage LED system to communicate battery and status information. A ring of LEDs on the front panel indicates power state, network connectivity, and battery percentage, with specific color patterns representing states such as initialization, adoption, or firmware upgrades. For example, a steady blue LED denotes normal operation, while flashing red signals a low battery, and alternating white/blue indicates firmware updating. This LED-centric approach aligns with UniFi’s existing product language and keeps the design minimalistic while relying on software integration for detailed telemetry.

Physically, the UPS-Tower fits neatly into a small office or studio environment, blending alongside UniFi routers or switches without dominating desk space. It operates quietly, with only a faint hum from the internal fan during battery mode. The 2U rackmount model, by contrast, uses a galvanized steel enclosure with front ventilation and nearly double the weight at 14 kg, prioritizing durability for data racks and wiring cabinets.

Both maintain an IP20 protection rating, ensuring basic safety against accidental contact but not dust or moisture resistance. Overall, UniFi’s approach emphasizes modularity, network integration, and compactness over display-driven functionality, positioning these UPS units as discreet but essential components within managed network setups.

The UniFi UPS-Tower UPS Review – Internal Hardware

Internally, the UniFi UPS-Tower follows a line-interactive architecture, combining voltage regulation with battery backup to ensure smooth transitions during power interruptions. The system utilizes an automatic voltage regulation (AVR) circuit that adjusts minor fluctuations in mains voltage without switching to battery mode, minimizing wear on the internal power cells. In the event of an outage or severe voltage dip, the UPS switches to battery operation within 6 to 10 milliseconds, maintaining output stability at 120V AC with a ±10% regulation margin. The waveform produced in battery mode is a simulated sine wave, which is adequate for most networking gear and consumer electronics, though not ideal for high-sensitivity audio, medical, or laboratory equipment. Power delivery remains consistent throughout short outages, allowing network hardware, NAS units, and servers to complete safe shutdown procedures.

The UPS-Tower contains a single 12V, 9Ah sealed lead-acid battery, user-removable via a bottom access panel. This design makes future maintenance straightforward, allowing owners to replace the battery when its capacity diminishes after several years of use. At full load (600W), the runtime averages around 2 minutes, while at half load, it extends to approximately 7 minutes before automatic shutdown. Recharge time to 90% capacity is listed at 6 to 8 hours. Thermal performance under sustained use is stable, and the inclusion of passive and active ventilation ensures no overheating under normal operating conditions. The system is also protected against short circuits, overloads, and over-voltage faults, automatically tripping into fault mode if thresholds of 110% to 120% load are exceeded.

Comparatively, the UPS-2U Rackmount uses a dual-battery setup with two 12V, 9Ah lead-acid modules to achieve 1,440VA / 1,000W output capacity. It shares the same waveform and transfer time but provides slightly extended runtime—2.3 minutes at full load and 8 minutes at half load—thanks to the added battery reserve. It also benefits from a galvanized steel chassis that enhances durability and is better suited for professional rack environments. Both systems are NDAA-compliant and certified under FCC, IC, UL 1778, and CSA C22.2 No. 107.3, ensuring safety and performance standards for commercial and residential use. In both models, system management and network telemetry are handled by a dedicated network controller chip, enabling UniFi OS integration and data synchronization with other UniFi devices.

The UniFi UPS-Tower UPS Review – Functionality

The UniFi UPS series is built around simplicity and ecosystem-level integration rather than feature-heavy configuration. Both the UPS-Tower and UPS-2U connect directly to the UniFi Network controller via Ethernet, where they appear alongside other UniFi devices for adoption. Once added, users can view real-time battery percentage, load level, input/output voltage, and system temperature directly from the UniFi interface. The units are also capable of sending power event notifications when mains power fails or returns, ensuring administrators receive alerts through the existing UniFi management system without relying on third-party monitoring software. This network-level approach allows the UPS to act as both a power backup and an automated coordination point for controlled shutdowns across UniFi infrastructure, such as Dream Machines, switches, or NAS units.

Integration with non-UniFi devices is handled through Network UPS Tools (NUT) compatibility. This makes the UPS-Tower particularly flexible in mixed environments where NAS devices or servers from other vendors, such as Synology or QNAP, require graceful shutdown when the UPS switches to battery mode. Users can define credentials and associate the UPS with NUT clients on the same network to relay status and trigger automated shutdowns once the battery reaches a predefined threshold. Although the review highlighted the lack of USB connectivity, which restricts plug-and-play use with devices expecting a traditional USB UPS handshake, the Ethernet management layer compensates by offering wider network-based communication. However, features such as per-device runtime configuration or selective port control are not yet implemented, leaving shutdown scheduling dependent on firmware updates or future model revisions.

The control and monitoring interface remains minimalistic, relying heavily on UniFi’s centralized GUI rather than onboard interaction. LEDs on the chassis provide a clear visual indication of status—covering power mode, adoption state, and battery level—but all deeper telemetry must be accessed through UniFi Network. Once paired, users can also configure email or push notifications for voltage irregularities, battery health alerts, and firmware updates. It is important to note that the current firmware does not support pure sine wave operation or lithium-ion battery upgrades, though UniFi has stated that future models will expand the portfolio to include these higher-end options. In its present form, the UPS-Tower and UPS-2U focus on stability, ease of deployment, and unified management within a single software environment, making them efficient for UniFi users seeking automation without added complexity.

The UniFi UPS-Tower UPS Review – Conclusion and Verdict

The UniFi UPS-Tower and UPS-2U represent the brand’s first foray into managed backup power systems, designed primarily to extend the reliability and consistency of the broader UniFi ecosystem. Both units share the same line-interactive architecture, simulated sine wave output, and Ethernet-based monitoring, offering a predictable and easily managed experience for users already invested in UniFi infrastructure. Their minimalist design, compact footprint, and seamless adoption through the UniFi Network Controller make them suitable for environments where simplicity, remote monitoring, and integration outweigh the need for advanced runtime management or pure sine wave output. For most small network or NAS setups, either model will provide adequate protection during short outages and brownouts, while ensuring systems are safely powered down when battery capacity is depleted.

However, their appeal remains closely tied to the UniFi ecosystem. The absence of USB connectivity, PoE passthrough, and lithium-ion battery options limits their usefulness in heterogeneous or high-performance environments. Users seeking pure sine wave support, longer runtimes, or advanced per-device control will likely need to wait for the next generation of UniFi UPS models, which the company has already suggested will expand to include these options. As they stand, the UPS-Tower and UPS-2U are well-built, tightly integrated, and cost-effective for UniFi users, but less compelling for those operating outside that ecosystem. They function precisely as intended: reliable, network-aware power backups for UniFi-managed systems, providing foundational stability rather than feature innovation.

Should You Upgrade Your Synology from DSM 7.2 to DSM 7.3?

DSM 7.3 represents Synology’s final major release under the DSM 7 platform before the expected transition to DSM 8, and it introduces a mix of refinements, policy reversals, and new enterprise tools that signal both the maturity and the approaching end of this software generation. The update arrives after an extended rollout period that began in mid-2025 and has been deployed gradually across supported NAS models to ensure stability. It brings several notable changes, most prominently the revision of the company’s restrictive hard drive policy under the new HCL 5.0 standard, allowing a broader range of third-party drives on 2025 Plus series systems. Other additions include the Synology Tiering package, designed to automate storage management between multiple NAS devices, and the introduction of the AI Console, a framework that integrates external AI and LLM providers into Synology’s productivity applications. Alongside these new components, DSM 7.3 also adds incremental updates such as native exFAT support, more flexible encryption handling, improved domain and directory management, and several kernel-level security patches.

However, for most existing users running DSM 7.2, the decision to upgrade should not be automatic. Many of the most visible features in DSM 7.3, including Synology Drive 4.0 and early versions of Synology Tiering, can already be accessed through separate beta packages on DSM 7.2 without performing a full system upgrade. Moreover, DSM 7.3 has arrived without a public beta phase, leading to mixed community feedback on compatibility issues and minor application regressions reported during early adoption. The release is stable for general use, but it represents an incremental refinement rather than a fundamental reinvention of Synology’s operating environment. For many users, DSM 7.3 serves as both a capstone for the current platform and a preparatory step toward the next-generation DSM 8 ecosystem expected to follow in 2026.

Should You Upgrade to Synology DSM 7.3? The TL;DR

For most existing Synology users, DSM 7.3 is a cautious, incremental update rather than a transformative one. It refines several areas—particularly in data security via vulnerability patches, encrypted storage handling, and drive compatibility—but few of these changes are critical for stable systems already running DSM 7.2. The improved drive policy on 2025 Plus models is a welcome reversal of the restrictive compatibility introduced earlier, yet older systems benefit little beyond quality-of-life improvements. Similarly, the new Synology Tiering and AI Console frameworks show potential but are limited in scope, requiring multi-system deployments or external AI integrations that do not suit typical home or small business users. In short, DSM 7.3 is reliable and functionally solid, but it introduces no must-have feature for those already content with DSM 7.2. Users with newer 2025 Plus series hardware, or those who need to take advantage of the new tiering, encryption, or administrative tools, can confidently upgrade once their model is supported. However, administrators running mission-critical workloads, media servers, or older legacy devices may prefer to wait until early 2026 for further stability updates or the initial DSM 8 previews. The release feels transitional—a final, polished step for the DSM 7 generation rather than a defining milestone—so unless your deployment directly benefits from one of its headline features, remaining on DSM 7.2 remains a perfectly reasonable choice.

Will Upgrading to DSM 7.3 Remove My Ability to Hardware Transcode?

Upgrading to DSM 7.3 does not remove hardware transcoding support on systems that already possess compatible integrated graphics or dedicated GPU functionality. The removal of hardware transcoding drivers occurred earlier, during the rollout of DSM 7.2.2, and affected only specific 2025-generation NAS models where Synology chose to disable HEVC (H.265) hardware acceleration for licensing and driver maintenance reasons. For all older devices—such as the DS920+, DS423+, and DS224+—the upgrade to DSM 7.3 preserves existing transcoding capabilities, including both H.264 and H.265 conversions, assuming these were functional in DSM 7.2. Users can continue to use hardware-assisted video conversion in applications such as Synology Video Station (if you still have it!), Plex, and Jellyfin without additional configuration. No drivers are removed or replaced by the DSM 7.3 upgrade process, and GPU-accelerated workloads remain fully accessible. The only cautionary point applies to future NAS models that will ship with DSM 7.3 preinstalled, as these may already reflect Synology’s newer driver policy, but existing systems upgrading from DSM 7.2 retain their transcoding performance entirely unchanged. Just remember that Synology 2025 series devices that have an integrated graphics CPU do NOT have the graphics driver by default. Watch the video below to learn more:

Will Upgrading to DSM 7.3 Result in My M.2 SSDs Becoming Unsupported or Unusable?

For most users, upgrading to DSM 7.3 will not cause any change to M.2 SSD functionality. Systems that already have existing cache or storage configurations using M.2 NVMe drives in DSM 7.2 will continue to operate normally after the upgrade, with no data loss or drive disconnection. The update does not remove support for previously installed third-party NVMe SSDs, nor does it alter existing caching or volume structures.

However, DSM 7.3 maintains Synology’s restrictive stance on creating new NVMe-based storage pools (i.e only their own bradned drives currently) or caches using unverified drives. While the broader HCL 5.0 policy restores open drive usage for SATA HDDs and SSDs on the 2025 Plus series, it does not extend to M.2 NVMe media, which still require official validation to be initialised in new roles. Users upgrading from DSM 7.2 who already have third-party M.2 drives configured will see no functional difference, but those attempting to add or reassign new NVMe devices after the upgrade will remain subject to the same compatibility enforcement introduced in DSM 7.2.

Is Synology Drive 4.0 Worth Upgrading to DSM 7.3 For?

Synology Drive 4.0 introduces a collection of small but practical improvements that enhance team collaboration and file management, but none of these changes require DSM 7.3 to function. The new version adds improved file labelling and categorisation tools, making it easier for teams to assign colour-coded or custom tags to shared content.

It also refines file request functionality, allowing users to specify reasons for requesting access and to track these submissions more transparently. File locking has also been expanded, now supporting manual control in addition to automatic version locking, which prevents conflicts when multiple users are editing the same document.

Together, these updates improve workflow precision and traceability, particularly in shared office environments or remote teams using Drive as a private alternative to cloud collaboration platforms such as OneDrive or Google Drive.

Beyond these refinements, Synology Drive 4.0 also brings stronger integration with Synology Account authentication, a requirement for accessing its newest collaborative features. This includes cross-user label sharing, improved audit tracking, and the option to enforce identity binding for Drive users in larger deployments.

However, all of these capabilities remain accessible to DSM 7.2 users via Synology’s beta package program, meaning there is no requirement to upgrade to DSM 7.3 to test or use them. Unless you specifically need tighter Drive account linkage or plan to adopt other DSM 7.3-only features such as Tiering or AI Console integration, the Drive 4.0 update alone does not justify upgrading your NAS operating system.

Is Synology Tiering Worth Upgrading to DSM 7.3 For?

Synology Tiering is one of the most significant new features in DSM 7.3, introducing an automated data management system designed to move infrequently accessed files from fast “hot” storage to lower-cost “cold” storage across multiple NAS devices. The concept is similar to hierarchical storage management in enterprise systems, but unlike QNAP’s QTier, it does not operate within a single NAS.

Instead, it requires two or more Synology NAS units running DSM 7.3, with the hot tier hosting the primary, frequently used data, and the cold tier configured as a secondary vault where less active files are migrated. Administrators can create tiering plans that determine how long a file remains in the hot tier based on modification or access frequency, with policies ranging from one day to several years. Transfers occur automatically over encrypted HTTPS connections, and stub files are left behind in the hot tier to preserve accessibility, allowing users to recall files seamlessly when needed.

However, despite its potential, Synology Tiering remains a beta-stage feature with limited configuration depth and hardware support. Not all NAS systems qualify for hot-tier deployment, and the supported model lists are inconsistent. For example, the DS425+—a system without M.2 slots—supports hot-tier operation, whereas the DS923+, which features greater performance and expandability, does not. Likewise, several older Plus-series models and most rackmount units are limited to cold-tier functionality only.

The service currently lacks integration with Synology Drive, encrypted folders, or other key DSM services, meaning many shared folders cannot participate in tiering policies. While the feature offers promise for businesses managing distributed sites or large archives, it is still early in development and unsuitable as the sole reason to perform a DSM 7.3 upgrade. It can also be tested independently on DSM 7.2 via the beta package, allowing administrators to evaluate its practicality before committing to a full system migration.

It is worth noting that Synology’s allocation of which NAS systems qualify as hot-tier and cold-tier devices under DSM 7.3 results in some unusual distinctions between models. Several systems with similar or even higher technical specifications are listed only as cold-tier devices, while others with more modest hardware are fully approved for hot-tier functionality.

For example, the Intel Celeron-based DS225+, which supports only SATA HDDs and lacks M.2 NVMe or 10GbE connectivity, is officially designated as a hot-tier system. In contrast, the AMD Ryzen R1600-based DS923+, which includes dual M.2 NVMe slots and 10GbE upgradability, appears only on the cold-tier list.

This creates a noticeable mismatch between capability and feature assignment across both desktop and rackmount systems, suggesting that Synology’s tiering support matrix has been determined on a per-model basis rather than by hardware class.

Model Listings (as defined under DSM 7.3):

• Hot-tier supported systems:
  FS6400, FS3600, FS3410, FS3400, FS2500, FS200T, HD6500, SA3400D, SA3200D, SA6400, SA3610, SA3600, SA3410, SA3400, RS4021xs+, RS3621xs+, RS3621RPxs, RS2825RP+, DS3622xs+, DS1823xs+, DS1621xs+, DS1825+, DS1525+, DS925+, DS725+, DS425+, DS225+.

• Cold-tier supported systems:
  HD6500, FS6400, FS3600, FS3410, FS3400, FS2500, FS200T, SA3400D, SA3200D, SA6400, SA3610, SA3600, SA3410, SA3400, RS4021xs+, RS3621xs+, RS3621RPxs, RS2825RP+, RS2423RP+, RS2423+, RS2821RP+, RS2421RP+, RS2421+, RS1221RP+, RS1221+, RS822RP+, RS822+, RS820RP+, RS820+, RS422+, DS3622xs+, DS1823xs+, DS1621xs+, DS2422+, DS1825+, DS1821+, DS1621+, DS1525+, DS1522+, DS1520+, DS925+, DS923+, DS725+, DS723+, DS920+, DS720+, DS620slim, DS425+, DS423+, DS420+, DS225+, DS224+, DS220+, DVA1622, DVA3221.

The division between these two groups highlights some unexpected choices, where NAS models with more advanced configurations—such as integrated NVMe storage or faster network options—are limited to cold-tier participation, while smaller, SATA-only systems are permitted full hot-tier operation.

Are Synology AI Admin Console Services Worth Upgrading to DSM 7.3 For?

The Synology AI Console is a new administrative framework introduced in DSM 7.3 that allows NAS administrators to connect external artificial intelligence and large language model (LLM) services, such as OpenAI, Azure OpenAI, Google Gemini, and Amazon Bedrock, directly into select Synology productivity applications. Its purpose is to enhance tools like Synology MailPlus and Synology Office with text summarisation, translation, and content generation capabilities.

Rather than hosting AI workloads locally, the Console acts as a bridge between the NAS and third-party AI providers through user-supplied API keys. Administrators can control who can access these features, set daily or per-minute token limits to manage consumption, and monitor all requests via detailed transaction logs.

A privacy-focused de-identification mechanism can also be enabled to mask sensitive data—such as names, IP addresses, or account details—before it leaves the NAS for external processing, restoring it upon return.

While these controls demonstrate a well-considered security approach, the AI Console remains divisive. Because all AI requests are processed externally rather than on-device, the system sends portions of MailPlus and Office text content to third-party cloud providers for analysis and response generation.

Even with encryption and masking in place, this design conflicts with the expectations of users who adopt a NAS precisely to maintain full local control over data.

Moreover, the Console currently supports only text-based functions and does not provide local inference, on-device LLM hosting, or GPU-accelerated processing, which limits its appeal to professional or privacy-conscious users. For most home and small-business owners, the AI Console is an optional enhancement rather than a compelling reason to upgrade.

It may benefit organisations already running MailPlus or Office in a collaborative environment, but its dependence on external AI infrastructure means its inclusion in DSM 7.3 is unlikely to justify a system-wide update on its own.

A Pre-emptive Warning about DSM 7.3 and Synology RS / Rackstation and NVR / DVA Surveillance Systems

While DSM 7.3 restores third-party hard drive flexibility on the 2025 DiskStation Plus range, this policy change does not extend to RackStation (RS) or DVA/NVR systems. These models continue to enforce Synology’s restricted compatibility framework, requiring officially verified HAT, HAS, or SAT series drives for full SMART monitoring, health data reporting, and warranty-backed operation. Unverified drives may still function but typically appear with degraded status indicators, limited temperature or lifespan data, and persistent “incompatible” warnings within Storage Manager.

This limitation remains particularly relevant to surveillance deployments, as Synology has yet to certify common NVR-grade drives such as Seagate IronWolf, Seagate SkyHawk, or WD Purple series models. At the time of writing, only one 2025-generation RackStation has been released under this policy, but Synology is expected to expand the line-up significantly into Q1 2026, with new models such as the DVA7400, DVA3000, and additional 4- and 8-bay RS systems all expected to ship with DSM 7.3 pre-installed and to follow the same verified-drive enforcement. As such, administrators planning future rackmount or surveillance deployments should confirm drive support in advance, as Synology shows no signs of relaxing its enterprise compatibility standards for these product tiers.

Should You Upgrade to DSM 7.3? VERDICT

For most existing Synology users, DSM 7.3 stands as a careful, incremental evolution of the platform rather than a major overhaul. It introduces refinements in data protection, encryption handling, and administrative control while restoring a more open stance on third-party hard drive use under the new HCL 5.0 policy. These adjustments address several long-standing user concerns, particularly on the 2025 Plus series, where Synology has finally reintroduced full flexibility for HDD and SSD compatibility. However, outside of that reversal, DSM 7.3’s core updates—such as minor kernel improvements, user interface refinements, and system efficiency tweaks—represent evolutionary stability rather than innovation. The release also marks Synology’s first attempt to integrate AI-based administrative tools and multi-tier storage, but both features remain optional, niche in scope, and better suited to advanced users or multi-NAS deployments. For those running stable DSM 7.2 environments, the upgrade is beneficial but not essential, as few of the new capabilities materially alter day-to-day operations.

That said, DSM 7.3 remains a worthwhile step forward for users who want to align their systems with Synology’s next-generation framework before DSM 8’s eventual release. Owners of newer 2025 models such as the DS925+, DS1525+, or RS2825RP+ will likely find the update unavoidable, as it forms the baseline for upcoming package releases and extended security support. Administrators managing large data environments may also appreciate the improved directory integration, enhanced file versioning, and native exFAT support included in this release. Still, those relying on older Plus or XS-class devices for media, backup, or general storage tasks may prefer to wait for a few minor revisions before upgrading, allowing early adopters to expose any unforeseen issues. DSM 7.3 is polished and well-structured, but it feels transitional—a bridge between legacy DSM 7.2 deployments and the more modern, AI-aware infrastructure Synology is preparing for DSM 8. Unless you specifically require its new storage policies, tiering capabilities, or AI integration, remaining on DSM 7.2 remains a stable, low-risk option for the foreseeable future.

Which Systems Support the DSM 7.3 Upgrade? (Updated List)

The DSM 7.3 (version 7.3-81180) update is available as a manual download for an extensive range of Synology NAS systems, spanning the Plus, XS, SA, FS, HD, Value, and J series. Rollout continues in stages, meaning some users will not yet receive an automatic update notification. Once installed, DSM 7.3 cannot be downgraded to a previous version, and for many older models, it will be the final feature-bearing update, with future maintenance limited to security and stability patches.

The complete set of DSM 7.3 installation files, as listed in Synology’s October 2025 release, confirms support for virtually all NAS models released between 2016 and 2025. Key model families include:

DiskStation desktop systems:
DS1019+, DS116, DS118, DS119j, DS120j, DS124, DS1517+, DS1517, DS1520+, DS1522+, DS1525+, DS1618+, DS1621+, DS1621xs+, DS1817+, DS1817, DS1819+, DS1821+, DS1823xs+, DS1825+, DS216+, DS216, DS216+II, DS216j, DS216play, DS218+, DS218, DS218j, DS218play, DS220+, DS220j, DS223, DS223j, DS224+, DS225+, DS2419+, DS2419+II, DS2422+, DS3018xs, DS3617xs, DS3617xsII, DS3622xs+, DS416, DS416j, DS416play, DS416slim, DS418, DS418j, DS418play, DS419slim, DS420+, DS420j, DS423+, DS423, DS425+, DS620slim, DS716+, DS716+II, DS718+, DS720+, DS723+, DS725+, DS916+, DS918+, DS920+, DS923+, DS925+.

RackStation and enterprise systems:
RS1219+, RS1221+, RS1221RP+, RS1619xs+, RS18016xs+, RS18017xs+, RS217, RS2416+, RS2416RP+, RS2418+, RS2418RP+, RS2421+, RS2421RP+, RS2423+, RS2423RP+, RS2818RP+, RS2821RP+, RS2825RP+, RS3617RPxs, RS3617xs+, RS3617xs, RS3618xs, RS3621RPxs, RS3621xs+, RS4017xs+, RS4021xs+, RS422+, RS816, RS818+, RS818RP+, RS819, RS820+, RS820RP+.

Data-centre and performance platforms:
FS1018, FS2017, FS2500, FS3017, FS3400, FS3410, FS3600, FS6400, HD6500, SA3200D, SA3400, SA3400D, SA3410, SA3600, SA3610, SA6400.

Video analytics and surveillance models:
DVA1622, DVA3219, DVA3221.

Virtual DSM package:
VirtualDSM 7.3-81180.

This dataset confirms that DSM 7.3 has been compiled for almost every currently supported platform, with file sizes ranging from roughly 300 MB for entry-level systems (such as the DS120j and RS217) up to 430 MB for enterprise and FlashStation devices. Users operating 2025-generation systems such as the DS225+, DS425+, DS725+, DS925+, DS1525+, DS1825+, RS2825RP+, and SA3410 will receive DSM 7.3 pre-installed or as part of first-release firmware. For older devices dating back to 2016–2018, DSM 7.3 will act as the final major update before DSM 8 arrives in 2026.

Which Synology NAS will See DSM 7.3 as their LAST Major Synology Update?

The DSM 7.3 (version 7.3-81180) update is available for a wide range of Synology NAS models, though rollout is staged and certain older systems will remain on DSM 7.2 or earlier. It is important to note that DSM 7.3 will be the final major upgrade for many devices, after which they will continue to receive only security and maintenance patches. Users should also be aware that once installed, DSM 7.3 cannot be downgraded.

Models eligible for DSM 7.3 upgrade:
FS Series: FS3017, FS2017, FS1018
XS Series: RS18016xs+, RS4017xs+, RS3617xs+, RS3617xs, RS3617RPxs, RS18017xs+, DS3617xs, DS3617xsII, DS3018xs
Plus Series: RS2416RP+, RS2416+, DS916+, DS716+II, DS716+, DS216+II, DS216+, DS1817+, DS1517+, RS2818RP+, RS2418RP+, RS2418+, RS818RP+, RS818+, DS1618+, DS918+, DS718+, DS218+, RS1219+
Value Series: DS116, DS216, DS216play, DS416, DS416play, DS1517, DS1817, DS418play, RS217, RS816
J Series: DS216j, DS416j, DS416slim, DS419slim, DS418j, DS218j, DS119j

For these devices, DSM 7.3 represents the end of the feature update cycle, effectively marking the transition point toward DSM 8, which will accompany newer 2026 and later hardware. Users operating 2025-series NAS systems that are produced by Synology in 2026 (the DS225+, DS425+, DS725+, DS925+, DS1525+, DS1825+, and RS2825RP+) will receive DSM 7.3 by default and will likely be among the first to transition to DSM 8 once available.

Is the Synology DS925+, DS1825+, DS1525+, etc NAS OK to Buy Now?

As this change in unverified hard drive support policy by Synology seems to be rolled out in the DSM 7.3 update, that means that currently if you buy and deply a Synology x25 generation NAS, you will still be subject to the restricted HDD deployment status of DSM right now (i.e cannot initialize, cannot RAID build, Rebuild, hot spare, etc unless using a Synology labelled drive or one that eventually might arrive on the compatibility list). So, if you buy the new Synology DS925+, DS1825+ or DS1525+ – unless you were already going to buy Synology hard drive and SSD media, you won’t be able to do very much out the box! So, if you are only considering a Synology NAS right now IF it can be used with 3rd party and/or unverified storage media – DO NOT BUY until the DSM 7.3 update rolls out! You will just be wasting some of your 3 year included warranty whilst you wait!

The Synology Hard Drive and SSD Support Change in DSM 7.3 Explained – What You Can/Cannot Do

With the release of DSM 7.3, Synology has formally introduced its latest and most detailed round of storage compatibility policies to date, outlining exactly which hard drives and solid-state drives are supported across its growing NAS product ecosystem. These updates arrive after several years of gradual tightening in Synology’s hardware validation process, which began in 2021 with the introduction of the HAT5300 and HAT3300 drives and became fully enforced in the 2024–2025 generation of devices. Under DSM 7.2, many of these newer systems—in particular the Plus series—were restricted to using Synology-branded drives only, effectively preventing users from creating storage pools with unverified third-party disks. This limitation led to considerable backlash from the community and power users who had relied on flexible drive choices for mixed or repurposed storage builds.

DSM 7.3 introduces a new structure to this policy, known internally as the HCL 5.0 framework, which partially relaxes those restrictions for 2025 model-year DiskStation Plus and J series NAS systems. It reinstates the ability to use non-listed hard drives and SATA SSDs for pool creation, while maintaining a degree of verification for higher-end systems such as the XS, SA, FS, and HD series. The update is significant because it rebalances Synology’s approach to drive validation, aligning reliability goals with user flexibility. In addition, DSM 7.3’s drive-handling system now displays clearer notifications within Storage Manager, differentiating between listed, unlisted, and incompatible drives, helping users understand the operational impact of their hardware choices before deploying them into active volumes or caches.

For professionals managing larger deployments, DSM 7.3 also provides expanded transparency on what Synology considers “verified reliability,” listing the precise categories of tests that certified drives undergo—thermal stress, power cycle endurance, and abnormal shutdown simulation—before being added to the official compatibility list. These details are especially relevant for IT administrators planning storage upgrades or migrations, as the new compatibility tables make it clear which drive types can be used in different Synology product families. This article breaks down the logic behind these changes, explains how Synology’s updated system reacts to various drive types, and clarifies which NAS lines now support third-party drives under DSM 7.3.

Why Synology Has Changed Hard Drive and SSD Support in DSM 7.3?

When the Synology 2025 PLUS series launched in spring 2025, Synology’s decision to restrict many newer NAS models to officially approved Synology-branded drives marked a major turning point in the company’s storage policy, triggering widespread criticism across its user base. Systems like the DS923+ and DS1522+ suddenly required drives from Synology’s HAT or SAT ranges for creating new storage pools, leaving long-time users frustrated that they could no longer use trusted third-party disks from vendors such as Seagate or Western Digital. Synology’s explanation at the time centered on reliability: they claimed a growing number of support incidents were linked to unverified drives with unstable firmware, inconsistent temperature readings, or poor power recovery behavior. The aim was to unify performance standards across the portfolio and ensure that every supported configuration met enterprise-grade validation tests already used in their FS and SA lines. However, as the backlash grew throughout 2024 and early 2025, it became clear that many customers—especially small businesses and home users—felt alienated by this rigid policy. Some migrated to alternative NAS ecosystems, while others publicly voiced concerns about the long-term openness of Synology’s platform. In response, Synology developed a new compatibility framework known as HCL 5.0, introduced in DSM 7.3, to strike a balance between reliability and flexibility. This new approach reinstates the ability to use unlisted hard drives and 2.5-inch SATA SSDs for storage pool creation on 2025 DiskStation Plus, Value, and J series models, provided the drives are not explicitly marked as incompatible. Meanwhile, enterprise systems such as the FS, SA, XS, and HD ranges continue to enforce strict compatibility for mission-critical stability. Synology described this as a pragmatic evolution of its policy, aligning with customer expectations while continuing to collaborate with major drive manufacturers to validate additional models under its new testing program. The result is a hybrid policy that protects Synology’s enterprise reliability standards but restores much of the flexibility and user confidence that defined the brand’s earlier systems.

What Happens When a User Installs a Hard Drive That Is Not on the Compatibility List but Is Not on the Incompatibility List Either?

Under DSM 7.3, Synology has overhauled how its NAS systems handle drives that are not officially listed in the compatibility database but are also not explicitly marked as incompatible. This new policy, part of the HCL 5.0 framework, restores the flexibility that was largely lost with DSM 7.2. For users of 2025 DiskStation Plus models, including systems such as the DS1525+, DS925+, and DS725+, these drives are now treated as fully functional and supported for installation, storage pool creation, and volume management. When a non-listed HDD or SATA SSD is installed in these units, DSM 7.3 accepts it without generating warnings, restrictions, or “unverified” messages. The drive behaves identically to a fully approved model, and users can create new RAID arrays, expand existing volumes, and use all standard DSM features such as snapshots, encryption, and Hyper Backup. This marks a significant shift from DSM 7.2, which blocked pool creation entirely if the installed drive was not verified by Synology.

The only distinction that remains is on the support side rather than the user interface. While DSM 7.3 operates normally with these drives, Synology’s technical support team may limit assistance for issues proven to be caused by non-listed hardware. This distinction allows experienced users to use mixed or legacy drives at their discretion while maintaining a clear boundary of responsibility. From a practical standpoint, performance, drive telemetry, and reliability monitoring remain fully available, including S.M.A.R.T. analysis, temperature reporting, and bad sector scanning. Storage pools built with these drives are indistinguishable from those using Synology-validated models, which means users can freely upgrade or migrate without worrying about feature loss.

The only exceptions to this open policy involve M.2 NVMe drives and systems outside the Plus, Value, or J series. NVMe SSDs used for caching or storage pools still require official validation because they endure heavier sustained write loads and generate more heat under continuous NAS workloads. As a result, only listed M.2 models can be used for new cache or pool creation, though previously configured drives can still be migrated. Meanwhile, enterprise-oriented NAS lines such as the RS, FS, SA, and XS series continue to operate under stricter compatibility rules, where only officially listed drives can be used for new storage pool creation. In these systems, non-listed drives can sometimes be recognized for migration, but cannot participate in new arrays or cache volumes.

For most users, this means that DSM 7.3 on the 2025 Plus series finally restores the traditional Synology experience: the ability to use virtually any NAS-grade hard drive or 2.5-inch SSD without restriction. It also removes the previous generation’s unnecessary barriers that alienated long-term customers. Synology has positioned this change as a response to community feedback, reaffirming that flexibility can coexist with reliability. The HCL 5.0 framework is now the baseline for all new consumer and prosumer systems, signaling Synology’s partial return to an open and more user-friendly storage policy.

How Is Hard Drive Compatibility in DSM 7.3 on the Rackstation/RS and NVR/DVA Surveillance NAS Systems?

While the original restrictions are expected (though not wholy welcome) for enterprise-grade units, DSM 7.3 also applies similar limitations to rackmount Plus (RS+) and DVA/NVR models, which has generated frustration among users expecting parity with desktop Plus series devices. Systems such as the RS2423RP+, RS422+, and DVA1622 remain governed by a more conservative policy, where only drives on the compatibility list can be used for new pool creation, and unlisted HDDs are accepted only for migration. In contrast to the new, flexible policy introduced for 2025 DiskStation Plus models, these rackmount and surveillance systems do not yet benefit from the same relaxed rules. This distinction is particularly disappointing given that many surveillance-optimized HDDs—such as Seagate’s SkyHawk or IronWolf ranges—have not yet been verified by Synology for DVA or NVR units, leaving buyers with fewer officially supported choices despite these drives being purpose-built for similar workloads.

The DVA and NVR product lines further complicate matters because their operating environments rely heavily on consistent write performance and power management behavior. Synology’s internal reasoning is that drive validation for continuous surveillance recording requires more predictable I/O latency and lower error recovery times than typical NAS workloads. However, the practical impact is a reduced range of compatible disks, even when many third-party NAS or CCTV-specific drives are known to perform reliably under similar conditions. Until Synology expands its verification program to include these models, administrators deploying rackmount Plus or DVA systems must continue to rely exclusively on officially listed drives or accept limited migration-only functionality.

These restrictions highlight an ongoing inconsistency in Synology’s product ecosystem. DSM 7.3 offers broad flexibility and open drive use on desktop Plus series systems but maintains enterprise-grade rigidity across rackmount Plus and surveillance-focused models. For now, this gap means that users deploying DSM 7.3 on RS or DVA systems cannot benefit from the same simplified, user-friendly drive policy available to standard DiskStation Plus NAS units.

How Is Hard Drive Compatibility in DSM 7.3 on the FS, HD, SA, UC, XS+, XS, and DP Series?

In DSM 7.3, Synology continues to apply the most stringent validation rules across its enterprise and datacenter-class NAS platforms, which include the FS, HD, SA, UC, XS+, XS, RS, and DP series. These systems are built for environments where sustained uptime, predictable throughput, and long-term data integrity are non-negotiable. As a result, they rely entirely on Synology’s Enterprise Compatibility Framework, which only permits the use of drives that have been formally validated and listed on the official compatibility database. These listed drives undergo intensive reliability testing, including extended read/write stress cycles, multi-node redundancy simulations, and controlled recovery from power or network failures. DSM 7.3 enforces this framework to guarantee consistent behavior across RAID arrays and to ensure that firmware-level optimizations, such as error recovery timing and caching algorithms, work as designed with Synology’s proprietary storage stack.

For users of these enterprise models, drives fall into three possible states: listed, not listed, and incompatible. Listed drives are fully supported for installation, storage pool creation, caching, and migration. Drives that are not listed may still appear in Storage Manager but are limited to migration-only use, meaning they can be mounted if they come from an existing Synology system but cannot be initialized for new volumes or RAID groups. This allows data recovery or transition from legacy setups without granting full functionality. Meanwhile, drives on the incompatibility list are blocked entirely and cannot be used in any capacity. These restrictions are designed to prevent firmware mismatches or mechanical inconsistencies that could undermine array stability. In practice, this means that enterprise and rackmount models remain tied to the official drive ecosystem, often limited to Synology’s own HAT or HAS series drives or verified OEM equivalents.

In these product classes, DSM 7.3 also maintains a strict policy for cache and SSD usage. M.2 NVMe drives can only be used for caching or storage pools if they appear on the official compatibility list. Unlisted M.2 drives are detected by the system but cannot be assigned to any cache operation, even for testing purposes. Similarly, 2.5-inch SATA or SAS SSDs that are not verified cannot participate in new array creation, even though they may mount for migration. This conservative approach reflects Synology’s focus on maintaining data integrity over flexibility in its upper-tier systems, where downtime or data corruption can carry substantial business costs. DSM communicates these restrictions clearly during setup: any attempt to use an unsupported drive for new pool creation will trigger a warning explaining that the operation cannot proceed due to compatibility enforcement.

What are the benefits of Buying Synology-branded Hard Drives and SSDs?

In parallel with the policy adjustments introduced in DSM 7.3, Synology has also begun expanding a series of benefits and incentives aimed at customers who purchase Synology NAS systems together with Synology-branded storage media. These initiatives are part of the company’s ongoing effort to strengthen its vertically integrated ecosystem, ensuring optimal performance and reliability when all components come from the same source. In selected markets, buyers who purchase Synology HAT, HAS, or SAT series drives on the same invoice as their NAS hardware now receive extended warranty coverage of up to five years, administered directly through authorized distributors and resellers. In addition, Synology has introduced an Express Replacement program, allowing for immediate drive swaps during the warranty period without waiting for the defective unit to be shipped and inspected, effectively mirroring the convenience of a premium RMA service. These benefits are available at no extra cost when drives are purchased through approved channels. The initiative is designed to make Synology’s validated ecosystem more appealing to businesses seeking predictable lifecycle management and faster recovery in the event of hardware failure, while also providing an incentive for users to standardize on Synology-branded components rather than mixing third-party storage.

DSM 7.3 and Hard Drive / SSD Support Conclusion

DSM 7.3 might well represent the most comprehensive and transparent storage compatibility framework Synology has released to date (after years of obviscation and unclear messaging), but it also reinforces a clear divide between its consumer and enterprise platforms. The introduction of the HCL 5.0 policy marks a pragmatic shift from the heavily restricted DSM 7.1/7.2 model, restoring the flexibility that long-time users had relied on for more than a decade. On the 2025 DiskStation Plus series, users can once again install and operate any third-party NAS-grade HDD or SATA SSD without limitation, bringing back the open and adaptable system design that helped define Synology’s reputation. This balance between openness and validation shows the company’s recognition of user feedback and its effort to rebuild trust after widespread criticism of its earlier drive-locking policy. By maintaining full functionality for unlisted drives while still reserving strict validation for high-end hardware, DSM 7.3 offers a compromise that keeps consumer-grade systems practical and professional-grade systems predictable. Not ideal, but better than what was already in place.

However, DSM 7.3 also underlines the growing separation between Synology’s desktop Plus models and its rackmount Plus, DVA, and enterprise systems. While home and small-business users benefit from restored flexibility, administrators working with rackmount or surveillance solutions remain tied to tightly controlled drive lists. The continued exclusion of common NAS and NVR-grade drives—such as Seagate IronWolf and SkyHawk or WD Purple series—from the verified list limits adoption and drives up deployment costs, particularly for surveillance users who require high-capacity, continuous-write storage. Until Synology expands its validation program or aligns its rackmount Plus systems with the same drive-handling rules as its desktop equivalents, this divide will remain a sticking point. DSM 7.3 is therefore both a meaningful correction and a reminder that Synology’s storage policy continues to evolve in response to user pressure. It moves the platform back toward flexibility without abandoning its enterprise reliability philosophy, but the differences between product tiers are now more visible than ever.

Synology (FINALLY) Gives In to 3rd Party HDD Support in 2025 PLUS Series NAS

7/10/25 – Updated with information supplied by Synology on how verifications and product ranges will support different HDD/SSD in DSM 7.3

Of all the stories of 2025, very few had the level of impact on the NAS industry that the Hard Drive support policy change by Synology did. Arguably THE name in the world of turnkey NAS, Synology enjoyed a fairly spotless reputation up until recent years, but when their gradual first-party support stance took a very drastic acceleration in April 2025 with a complete lockout of HDDs from Seagate and WD for their 2025 generation of hardware, the industry responded very, very unfavourably (Ed – understatement of the YEAR). Over the months that followed, even some of the biggest tech platforms and consumer rights focused media outlets on the internet made damning statements about the brand’s actions, previously very Synology-friendly outlets either criticised the move or simply ceased covering Synology, and even typically heavily supportive Synology-associated platforms such as the Synology subreddit and yes even here at NASCompares were keen to highlight every inconsistent turn of this story. After six months of heavy fire, undoubtedly poor sales of the 7–8 released Synology 2025 generation hardware launches in that time (eg DS925+, DS1825+, DS425+, etc), repeated missteps by the brand in user engagement (such as disabling comments on videos, contradictory press statements and baffling justifications around hardware)… now… NOW the brand has announced that you will once again be able to use Seagate and WD Hard Drives on the Synology 2025 generation of devices – and importantly, this time without the level of shouted alerts and warnings. So, let’s discuss when this WD and Seagate Hard Drive media support is coming back, what are the limits, is this too little too late and whether all this was ever worth it for Synology.

When and How Will Third-Party Hard Drive Support Return to the 2025 Synology NAS?

Synology has detailed that third-party hard drive support will return to 2025 devices alongside the rollout of DSM 7.3, the next major update to the Synology software platform. Unlike previous statements earlier this year, this U-turn now means that Seagate and WD drives will not only be usable again but also with a significant reduction (possibly even complete removal – still awaiting exact testing of DSM 7.3 ourselves) from the constant “unverified drive” and “at risk” warnings that plagued users. This represents a return to the compatibility model users were familiar with before 2025. Exact rollout dates of the DSM 7.3 update are still pending (likely Q4 2025 or early Q1 2026), but this will mark the point where Synology’s 2025 NAS systems no longer block unsupported drives at installation. Until that update arrives and users proceed with it’s installation, Synology 2025 systems will of course still not allow unconfirmed media to initialise DSM. Likewise, it remains unclear how the update will interact with users who have already employed community scripts to bypass restrictions – whether these fixes will still be needed, or whether DSM 7.3 will overwrite them entirely.

Another important detail is how far this reinstated compatibility extends. According to Synology’s new position in the DSM 7.3 rollout, users will again be able to initialise DSM, create storage pools, volumes, run disk checks, expand pools, perform RAID repairs and create hot spare disks – essentially restoring the same functionality that was lost earlier this year. Crucially, the obtrusive warning messages that previously accompanied unsupported drives will be removed, which means the user experience should be indistinguishable from older Synology generations. Synology has stated that testing of specific Seagate and WD drives was still “ongoing” in the last 6 months, but this appears largely academic now, since DSM 7.3 will no longer enforce the same restrictions. Which brings into question the validity of those claims. In practice though, this means users can once again choose from the wider drive market, without fear of blocked features or disruptive alerts. It is still not 100% clear on what the position regarding M.2 NVMe SSDs and Storage Pool use will be, as well as if this is going to be completely brand wide – or just affecting the PLUS series new and old that are eligible for the DSM 7.3 update.

The Alerts and ‘Warnings’ that users have gotten used to up tll now (i.e pre DSM 7.3 roll out):

To confirm, the current 2025 systems that primarily this Synology U-turn on Hard Drive compatibility in DSM would affect are:

• Synology DS925+
• Synology DS1525+
• Synology DS725+
• Synology DS1825+
• Synology DS425+
• Synology DS225+
• Synology RS2825RP+

Previous PLUS series devices did not arrive with the exceedingly strict ‘no verified = no initialization’ rule that the above system’s had, so although these will benefit in DSM 7.3 with lessened warnings that they currently had, it is not the deal breaker proposition that it is/was in the x25 series.

However, let’s return to the point. Was ALL of this chaos by Synology worth it? Was there actually a coherent strategy in place here? Let’s discuss the damage that the last 6 months have caused.

What Happens When a User Installs a Hard Drive That Is Not on the Compatibility List but Is Not on the Incompatibility List Either?

Under DSM 7.3, Synology has overhauled how its NAS systems handle drives that are not officially listed in the compatibility database but are also not explicitly marked as incompatible.

When a non-listed HDD or SATA SSD is installed in these units, DSM 7.3 accepts it without generating warnings, restrictions, or “unverified” messages. The drive behaves identically to a fully approved model, and users can create new RAID arrays, expand existing volumes, and use all standard DSM features such as snapshots, encryption, and Hyper Backup. This marks a significant shift from DSM 7.2, which blocked pool creation entirely if the installed drive was not verified by Synology.

The only distinction that remains is on the support side rather than the user interface. While DSM 7.3 operates normally with these drives, Synology’s technical support team may limit assistance for issues proven to be caused by non-listed hardware. This distinction allows experienced users to use mixed or legacy drives at their discretion while maintaining a clear boundary of responsibility. From a practical standpoint, performance, drive telemetry, and reliability monitoring remain fully available, including S.M.A.R.T. analysis, temperature reporting, and bad sector scanning. Storage pools built with these drives are indistinguishable from those using Synology-validated models, which means users can freely upgrade or migrate without worrying about feature loss.

The only exceptions to this open policy involve M.2 NVMe drives and systems outside the Plus, Value, or J series.

For most users, this means that DSM 7.3 on the 2025 Plus series finally restores the traditional Synology experience: the ability to use virtually any NAS-grade hard drive or 2.5-inch SSD without restriction. It also removes the previous generation’s unnecessary barriers that alienated long-term customers. Synology has positioned this change as a response to community feedback, reaffirming that flexibility can coexist with reliability. The HCL 5.0 framework is now the baseline for all new consumer and prosumer systems, signaling Synology’s partial return to an open and more user-friendly storage policy.

How Is Hard Drive Compatibility in DSM 7.3 on the FS, HD, SA, UC, XS+, XS, and DP Series?

In DSM 7.3, Synology continues to apply the most stringent validation rules across its enterprise and datacenter-class NAS platforms, which include the FS, HD, SA, UC, XS+, XS, RS, and DP series. These systems are built for environments where sustained uptime, predictable throughput, and long-term data integrity are non-negotiable. As a result, they rely entirely on Synology’s Enterprise Compatibility Framework, which only permits the use of drives that have been formally validated and listed on the official compatibility database.

Is it Too Little, Too Late? Is the Damage to the Synology Brand Already Done?

It’s a valid point. As mentioned in the intro, Synology has been a brand that, short of a few knocks along the way, has had a sterling reputation. Although their hardware has often been a little underwhelming, the software and services have been largely A1. But the move by Synology in restricting the use of drives from brands such as Seagate and WD burned A LOT of bridges. One cannot imagine that Western Digital or Seagate Technology were especially pleased by the rebuke either. The backlash was immediate and huge. Numerous sources I have spoken to in Europe and the U.S regarding Synology PLUS series sales (even for the 2023/22/21 ranges) confirmed the same sentiment: “Synology Diskstation sales were at a fraction of the previous year.” How much these support changes impacted enterprise solutions is unconfirmed, but given the number of sys-admins who quietly admitted to changing their buying plans, and sales teams who admitted recommending other vendors when Synology quotes became less competitive, the damage over the last 6 months has been palpable.

However, what about the next six months? Or the next 12 or 24? The timing of Synology’s disastrous hard drive support policy flip-flop could hardly have been worse. Alongside tech buyers (home and business) having tighter budgets due to rising costs, international trade tariffs being debated, new players entering the NAS industry, and rising expectations of what a system should do, Synology could not have chosen a worse moment for an unpopular policy. Many users who saw the way the policy was rolled out interpreted it as “the writing on the wall” and changed their stance on the brand. Some already jumped ship to alternative vendors, and others opted for older Synology hardware from pre-2025 ranges to avoid the lockout. For those buyers, the fact that the restrictions are now being removed will feel like a bitter twist – they could have had the newer hardware with the same freedom if they had simply waited a little longer.

How much of this shift can be attributed to public and media backlash is hard to quantify, but the scale of the U-turn speaks for itself. This is not the first time Synology has reversed course under pressure. Back in 2021/22, when DSM 7.0 introduced the earliest versions of its compatibility enforcement with red critical warnings, the outcry forced a retreat in DSM 7.1 to amber warnings instead (read here). History has now repeated itself on a much bigger stage. The difference is that this time, months of poor reviews, negative coverage, and lost sales will remain part of the public record, and Synology will struggle to erase that damage.

Much like QNAP and its long-running association with Deadbolt ransomware attacks, Synology may find that users do not easily forget this saga. For months, the internet has been awash with angry comments, critical reviews, and valid frustration at the brand’s direction. Even with DSM 7.3 restoring full drive freedom, the stigma of this six-month debacle will linger. Some users will never return. Others will approach Synology with renewed caution, mindful that the company could change course again in the future. The reaction from existing and potential Synology PLUS series NAS users was loud enough that I felt compelled to make two videos SPECIFICALLY because users were DM’ing and commenting about why I/NASCompares was continuing in our coverage of this brand:

Is the Synology DS925+, DS1825+, DS1525+, etc NAS OK to Buy Now?

As this change in unverified hard drive support policy by Synology seems to be rolled out in the DSM 7.3 update, that means that currently if you buy and deply a Synology x25 generation NAS, you will still be subject to the restricted HDD deployment status of DSM right now (i.e cannot initialize, cannot RAID build, Rebuild, hot spare, etc unless using a Synology labelled drive or one that eventually might arrive on the compatibility list). So, if you buy the new Synology DS925+, DS1825+ or DS1525+ – unless you were already going to buy Synology hard drive and SSD media, you won’t be able to do very much out the box! So, if you are only considering a Synology NAS right now IF it can be used with 3rd party and/or unverified storage media – DO NOT BUY until the DSM 7.3 update rolls out!

Prime Big Deal Day Bargains on Synology, QNAP, UGREEN, Terramaster, Seagate and More to Watch

That’s right, it’s that time once again—Amazon Prime Big Deal Day 2025 has arrived. The biggest e-retail giant in the world is rolling out its annual mega sale, and for those of us with a Prime subscription quietly siphoning cash every month, now’s the time to get something back. Whether you’re a home user looking to back up your devices or a business admin in need of robust storage solutions, Prime Day has consistently proven to be a great opportunity to upgrade your setup without breaking the bank. Unlike Black Friday—which tends to sprawl out across weeks and multiple platforms—Prime Day is a more concentrated event. That means the window to make a decision is often brief, and the best deals can vanish in hours, sometimes even minutes. So if you’re eyeing that NAS you’ve been meaning to buy or hoping to expand your RAID array with some fresh HDDs or SSDs, now’s the time to act fast. Today, we’re rounding up as many of the best Amazon Prime Day deals on NAS and storage tech as we can find. That includes offers on popular brands like Synology, QNAP, WD, Seagate, Terramaster, and others. Alongside the real-time deals that we (me and Eddie—yes, still working double shifts!) track throughout the event, we’ve also put together a list of recommended hardware to watch for. Many of these devices pop up on lightning deals with limited stock, so having a shortlist in mind can really help.

Important Note – Every year, we run these Prime Day and Black Friday deal pages the same way: by personally curating the offers we believe are genuinely worth it. If it’s not something we’d buy ourselves, we won’t include it. You can also contribute and share any bargains you come across using the community deal-sharing tool below. We do this for a couple of reasons. First, to help people make smarter decisions with their tech purchases. Second, because every time someone clicks a deal link and makes a purchase, we receive a small commission from Amazon—no extra cost to you. That affiliate income directly supports the site and allows us to keep producing NAS guides, reviews, and how-to content every single day. So, whether you’re looking to finally set up your first Plex server, expand your surveillance system, or just secure a better backup routine—there’s a good chance something will be on offer during Prime Day 2025.

UGREEN DXP4800 PLUS vs DH4300 NAS – Which Should You Buy?

UGREEN’s emergence into the NAS market has been notably rapid, expanding from its early DXP series Kickstarter campaigns in 2024 to a full retail presence in 2025. Among its growing portfolio, two models now define the entry and mid-range segments of the company’s lineup: the DH4300 Plus and the DXP4800 Plus. Both are 4-bay NAS systems built around UGREEN’s in-house UGOS Pro operating system, offering cross-platform client access, RAID options, and remote synchronization. However, beneath their similar exteriors lie significant differences in design philosophy, hardware architecture, and expandability. The DH4300 represents the brand’s low-power ARM-based solution focused on simplicity and efficiency, while the DXP4800 Plus adopts an Intel x86 platform that aims to deliver higher throughput, broader software compatibility, and long-term scalability. This comparison examines each system in detail to identify where their strengths diverge and which one may better align with different user priorities.

DH4300 vs DXP4800 PLUS – Design and Storage

Both the DH4300 Plus and DXP4800 Plus are 4-bay NAS systems, yet their physical execution and approach to storage differ substantially. The DH4300 Plus adopts a compact vertical cube form, measuring just 155mm per side, prioritizing low noise and minimal desk footprint. It uses plastic top-loading trays that can house either 2.5-inch SSDs or 3.5-inch HDDs. Drives are inserted vertically from the top, secured internally via SATA connectors. This layout helps keep the system small and easy to position in tighter setups but limits front-access servicing and restricts the unit’s suitability for hot-swap drive replacement. The DXP4800 Plus, by contrast, uses a more conventional front-loading 4-bay metal chassis that resembles traditional NAS systems from Synology or QNAP. Each tray includes a locking mechanism, supports hot-swapping, and accepts both 3.5-inch and 2.5-inch media. The metal body contributes to improved heat dissipation and rigidity, though it also results in higher weight and slightly higher fan noise. The chassis design clearly targets users expecting long-term durability and easier drive maintenance.

Beyond the drive trays themselves, the DXP4800 Plus expands the internal storage configuration by adding two M.2 NVMe slots. These can be assigned for SSD caching or as additional high-speed storage pools. This flexibility is absent in the DH4300 Plus, which is limited to its four SATA bays. The M.2 capability allows the DXP4800 Plus to create tiered storage setups that combine large-capacity HDDs with SSD acceleration, a feature relevant to media libraries or multi-user data environments requiring rapid retrieval. A key architectural distinction lies in their system drives. The DH4300 Plus relies on a 32GB eMMC flash module, while the DXP4800 Plus integrates a 128GB NVMe SSD dedicated to UGOS Pro. The SSD delivers faster system responsiveness, reduced latency, and provides enough capacity to install alternative operating systems if the user chooses. The eMMC module, while efficient, is considerably slower and less flexible for advanced tasks such as dual-boot environments or virtualized OS installations.

Both systems officially support up to 30TB drives per bay, giving the DH4300 Plus a theoretical ceiling of 120TB, while the DXP4800 Plus extends to 136TB when the NVMe bays are included. The practical implication is straightforward: the DXP4800 Plus provides more room to grow, both in capacity and performance scaling. For users seeking long-term expandability and tiered storage, the Intel-based unit presents the more adaptable platform. Meanwhile, those prioritizing compactness, lower power draw, and quiet operation may find the DH4300 Plus’ simplified vertical design sufficient for modest home or small-office workloads.

DXP4800 PLUS vs DH4300 – Internal Hardware

The UGREEN DH4300 Plus is powered by a Rockchip ARM processor built on a big.LITTLE configuration consisting of four Cortex-A76 and four Cortex-A55 cores, clocked at up to 2.0GHz. This eight-core design is efficient and well-suited for basic NAS tasks such as file sharing, backups, and light multimedia use. The processor is paired with 8GB of LPDDR4X memory that is soldered to the mainboard and non-upgradable. Power efficiency is a major strength of this configuration, typically consuming less than half the power of Intel-based systems when idle. However, its ARM architecture inherently restricts compatibility with x86 applications, virtual machines, and certain Docker containers, limiting its scope for heavier workloads.

By contrast, the DXP4800 Plus employs an Intel Pentium Gold 8505, a five-core, six-thread processor from Intel’s 12th Generation “Alder Lake” family. This hybrid x86 chip combines a single Performance core and four Efficient cores, supporting hardware virtualization, AVX2 instruction sets, and Intel UHD Graphics. Paired with 8GB of DDR5 memory, expandable up to 64GB, the DXP4800 Plus accommodates far more demanding tasks, including Docker deployments, Plex hardware transcoding, and multiple concurrent user operations. The use of DDR5 not only increases bandwidth but also introduces on-die error correction (ODECC) for improved data integrity, especially under sustained workloads.

Thermally, the two models are built with different cooling philosophies. The DH4300 Plus relies on its plastic housing and a single rear fan to quietly manage airflow, maintaining modest heat output even under continuous drive access. The DXP4800 Plus uses a metal chassis with enhanced thermal conduction and larger active cooling components to handle its higher power draw and CPU thermal output. As a result, it operates at a higher baseline wattage but sustains performance under extended heavy loads without throttling.

The difference between these platforms is clear: the DH4300 Plus targets efficiency and affordability, while the DXP4800 Plus prioritizes raw performance, expandability, and compatibility. The ARM-based model functions effectively as a quiet, low-cost personal cloud, whereas the Intel-powered alternative transitions closer to a professional or prosumer NAS capable of handling heavier workloads and future expansion.

DH4300 vs DXP4800 PLUS – Connectivity

The connectivity options on these two NAS systems reinforce their differing design priorities. The UGREEN DH4300 Plus offers a minimal, streamlined interface aimed at simplicity. It features a single 2.5GbE LAN port, sufficient for small network environments or home setups. This port provides adequate throughput for multi-user file access, media streaming, and backups, but limits scalability for link aggregation or 10GbE network integration. On the front, the DH4300 Plus includes one USB-C (5Gb/s) and two USB-A (5Gb/s) ports for connecting external storage or peripheral devices. Around the back, a 4K HDMI 2.0 output is provided, allowing direct media playback or access to the NAS desktop interface through a monitor and keyboard. Although compact and functional, the absence of additional network interfaces or expansion options means the DH4300 Plus is a closed system with limited upgrade flexibility.

The DXP4800 Plus presents a markedly broader I/O profile. Networking is handled by both a 2.5GbE and a 10GbE RJ45 port, enabling dual-network configurations, link aggregation, or high-speed connectivity to 10GbE switches and workstations. This combination provides a clear advantage for environments with large data transfers, such as video editing, virtualization, or backup synchronization across multiple systems. USB connectivity is also improved, with a front USB-C and USB-A port (each 10Gb/s), plus three additional rear USB-A ports—one at 5Gb/s and two at USB 2.0 speeds for legacy devices. The inclusion of an SD 3.0 card reader on the front panel enhances convenience for photographers or media professionals who regularly import content.

Both models offer HDMI output supporting 4K display, but only the DXP4800 Plus benefits from Intel’s integrated UHD Graphics, allowing smoother playback and better compatibility with third-party applications such as Plex, Jellyfin, or VLC in a connected display mode. The DH4300’s ARM GPU can output a graphical interface but struggles with higher bitrates and complex codec formats. Neither system includes PCIe or Thunderbolt expansion, although the DXP4800 Plus is more likely to support future USB-based expansion storage, given its higher USB bandwidth and processing headroom.

The result is a distinct separation in capability: the DH4300 Plus offers the essentials for simple network storage and direct access, while the DXP4800 Plus is engineered to serve as a central node in more advanced home or office networks, handling high-speed workflows and multi-interface operations with ease.

DH4300 vs DXP4800 PLUS – Software and Services

Both NAS systems operate on UGREEN’s UGOS Pro, the company’s in-house Linux-based operating system that has evolved considerably since its debut. UGOS Pro delivers a browser-accessible interface and companion apps for desktop and mobile devices, providing cross-platform file management, media streaming, and remote synchronization. Both the DH4300 Plus and DXP4800 Plus share the same core software experience, including snapshot protection, multi-tier backup utilities, RAID configuration tools, and cloud synchronization with popular platforms such as Google Drive, Dropbox, and OneDrive. Remote access can be achieved through relay services or secure connections such as Tailscale VPN, enabling users to maintain access without direct port forwarding.

Where the differences begin to emerge is in application scope and performance. The ARM-based DH4300 Plus supports a subset of the total UGOS Pro app library, running core services such as file sharing, photo management, and music/video playback, but it is limited when it comes to containerization and virtualization. Its CPU architecture prevents the use of virtual machines and restricts Docker to lightweight ARM-compatible containers. This makes it a suitable platform for personal data hosting or small-scale media libraries but less appropriate for professional or experimental use cases.

The DXP4800 Plus, leveraging its Intel x86 CPU and larger memory capacity, unlocks the full UGOS Pro ecosystem. It supports Docker for containerized applications and a dedicated Virtual Machine Manager, allowing users to run Windows, Ubuntu, or Android environments directly on the NAS. This hardware advantage extends to AI-based services integrated into UGOS Pro, including facial and object recognition within the Photo app. The DXP4800 Plus processes these functions locally at higher speed and with greater precision, while the DH4300 Plus delivers only basic recognition due to its lower AI compute capability.

Media handling is another clear differentiator. Both NAS units can run the native UGREEN Theater app for video playback, but the DXP4800 Plus benefits from hardware-accelerated 4K transcoding via Intel UHD Graphics. This enables smooth playback across Plex, Jellyfin, and Emby, even for HEVC or high-bitrate formats. The DH4300 Plus lacks equivalent hardware decoding support and therefore relies on software rendering, which can lead to stuttering or incompatibility when streaming demanding media.

Overall, UGOS Pro maintains functional parity across both systems at the surface level, yet the DXP4800 Plus unlocks a broader range of use cases—from virtualization to heavier AI and multimedia workloads. The DH4300 Plus remains best suited to users seeking a straightforward, reliable network storage environment without advanced compute or scalability expectations.

DXP4800 PLUS vs DH4300 – Verdict & Conclusion

The UGREEN DH4300 Plus and DXP4800 Plus ultimately cater to two very different categories of users, despite sharing the same UGOS Pro ecosystem and similar 4-bay configurations. The DH4300 Plus is built for simplicity, energy efficiency, and quiet continuous operation. Its ARM-based design consumes far less power and generates minimal heat, which is appealing for users who want a NAS that can run 24/7 in a home or office without significant energy cost or noise impact. It handles standard NAS duties—file storage, scheduled backups, photo management, and light multimedia playback—without issue. However, its hardware limitations restrict its suitability for more advanced workloads such as containerized apps, virtual machines, or high-resolution video transcoding. This makes the DH4300 Plus ideal for users seeking dependable, local network storage that functions as a personal cloud or central backup hub, not as an extensible compute platform.

The DXP4800 Plus, on the other hand, occupies a very different space in UGREEN’s product strategy. Its x86 Intel processor, DDR5 memory, dual-network connectivity (including 10GbE), and support for NVMe caching elevate it closer to what many would consider a professional-grade NAS system. It offers faster response times, wider compatibility with third-party applications, and a platform that supports future scalability through additional storage, memory, and software deployments. This system also opens the door to real virtualization, Docker-based workloads, and higher performance in media services thanks to Intel’s hardware-accelerated graphics. While it requires more power and a higher upfront investment, it delivers a measurable leap in flexibility, stability under heavier loads, and long-term performance headroom.

In practical terms, the DH4300 Plus will satisfy users who simply want to move away from cloud reliance, consolidate data locally, and maintain low running costs. The DXP4800 Plus suits those who expect their NAS to perform as both a data server and an active processing node for AI indexing, 4K media handling, or business-level file operations. Both systems are well-built, and UGOS Pro continues to mature into a stable operating environment, but the DXP4800 Plus clearly represents the more capable and future-ready choice. The DH4300 Plus fulfills its role as a compact, accessible entry into local network storage, while the DXP4800 Plus defines UGREEN’s current benchmark for serious, performance-oriented users.

Minisforum MS-01 vs MS-A2 – Which Should You Buy?

Minisforum has steadily earned recognition in the compact workstation space, and the MS-01 stands as one of its most prominent entries. Released with a focus on balancing high-performance hardware in a small chassis, the MS-01 quickly found popularity among professionals needing powerful networking and scalable internals without the bulk of a full-sized desktop. It supports CPUs up to the Intel Core i9-13900H, includes dual 10GbE SFP+ ports, and provides expansion via a PCIe 4.0 x16 slot (operating at x8 speed), giving users access to discrete graphics or high-performance cards if needed. With three internal M.2 slots and support for up to 64GB of DDR5 memory, the MS-01 became a go-to mini workstation for users who value connectivity and component flexibility at a relatively modest price point.

In early 2025, Minisforum introduced the MS-A2 — a system clearly designed as a next-generation counterpart to the MS-01, but one that leans into AMD’s latest advancements. Featuring the Ryzen 9 9955HX processor based on the Zen 5 architecture, the MS-A2 offers more cores, more threads, faster base and boost clocks, and higher supported memory capacity, reaching up to 96GB DDR5 at 5600MHz. It also brings upgrades in memory bandwidth, M.2 storage speed (with all three slots supporting PCIe 4.0 x4), and internal thermal design. From a feature standpoint, the MS-A2 is positioned to meet or exceed the MS-01 in most categories — but it does so with a noticeable bump in price. Still, for users prioritizing top-end performance and storage throughput, the MS-A2 might justify the premium. The sections below break down how these systems stack up in real-world terms — not just on paper, but in actual deployment.

Minisforum MS-A2 vs MS-01 – Hardware Specifications Compared

At a glance, both the MS-01 and MS-A2 share a near-identical chassis, measuring 196×189×48mm and following Minisforum’s signature small form factor aesthetic. Internally, however, there are several notable differences that affect both systems’ expandability and long-term utility. Both devices feature three M.2 slots for high-speed NVMe SSDs, but only the MS-A2 supports full PCIe 4.0 x4 lanes on all three slots. By contrast, the MS-01 includes a single PCIe 4.0 x4 slot, one PCIe 3.0 x4 slot, and one limited PCIe 3.0 x2 slot. This directly impacts storage performance, especially for users aiming to run multiple high-throughput drives in parallel. In real terms, the MS-A2 allows up to three SSDs each capable of saturating 7,000MB/s read speeds, whereas the MS-01 will bottleneck in its second and third storage bays.

Both systems include a PCIe 4.0 expansion slot, which is a rare and welcome inclusion in mini PCs. On the MS-01, this slot is x16 physically but electrically operates at x8 speed and is suitable for half-height, single-slot PCIe cards. The MS-A2 retains this format but introduces PCIe bifurcation support, enabling more advanced setups with compatible cards — a notable advantage for developers or users building niche use cases like NVMe RAID or multi-GPU compute tasks in an edge environment. Additionally, memory support is slightly more capable on the AMD model, with the MS-A2 supporting up to 96GB of DDR5-5600 via two SO-DIMM slots, compared to the MS-01’s 64GB ceiling at DDR5-5200. This can make a tangible difference in virtualization or memory-intensive creative workflows.

In terms of connectivity, both units are very well equipped: dual 10GbE SFP+ ports, dual 2.5GbE RJ45, HDMI output, USB 3.2 Gen1/Gen2 Type-A ports, and USB4 (or USB-C with DisplayPort alt mode). The MS-A2 takes a slight lead in display output capabilities, supporting HDMI 2.1 and DisplayPort 2.0 over USB-C, compared to HDMI 2.0 and DisplayPort 1.4a on the MS-01. This means the AMD system supports 8K60 and 4K144 video streams natively. Wireless capability is also a step ahead on the MS-A2 with Wi-Fi 6E and Bluetooth 5.3, compared to the MS-01’s Wi-Fi 6 and Bluetooth 5.2. Altogether, while the MS-01 still holds up well a year after release, the MS-A2 offers clearly improved throughput, higher bandwidth components, and better display and wireless standards.

Minisforum MS-01 vs MS-A2 – CPUs Compared

The defining difference between the Minisforum MS-01 and MS-A2 lies in their processor choices: the Intel Core i9-13900H and the AMD Ryzen 9 9955HX, respectively. While both CPUs are built for high-end mobile performance and boast identical peak boost clocks of up to 5.4GHz, the underlying architecture and core configurations are markedly different. The i9-13900H uses a hybrid architecture with 6 performance cores and 8 efficiency cores, totaling 14 cores and 20 threads. In contrast, the Ryzen 9 9955HX employs 16 full-fledged performance cores and 32 threads based on AMD’s latest Zen 5 architecture. For users engaged in parallel processing tasks—such as 3D rendering, large-scale compilation, or virtualization—the extra cores and threads in the AMD chip deliver a tangible performance uplift.

Zen 5 is a notable advancement over its predecessors, built on TSMC’s 4nm process and optimized for both performance and power efficiency. This gives the Ryzen 9 9955HX a structural advantage in multithreaded scenarios, with improved instruction throughput, cache handling, and memory bandwidth. The Intel Core i9-13900H, based on Raptor Lake and fabricated using Intel’s “7” process (a refinement of their 10nm SuperFin node), holds its own with mature thread management and strong single-thread performance. Its support for Intel’s Thread Director technology ensures efficient scheduling across its mixed-core layout, which can be beneficial in workloads like content creation and lightly-threaded business apps. However, the Ryzen chip’s unified core design tends to yield more predictable and consistent scaling when all threads are pushed simultaneously, reducing thermal spikes and improving overall sustained performance.

Thermal and power characteristics further highlight the gap between the two systems. Intel’s i9-13900H has a base power of 45W but can boost up to 115W under load, while AMD’s Ryzen 9 9955HX has a configurable TDP ranging from 55W to 75W. Although the Intel chip has a higher upper limit, in practice it tends to spike power draw during short workloads and then throttle back. In comparison, the Ryzen CPU maintains a steadier thermal and power profile over longer tasks. This behavior was reflected in sustained tests over one-hour and 24-hour windows under mixed network and compute usage: the MS-A2’s CPU performed more consistently, with lower long-term thermal build-up, aided by its upgraded internal fan design. Combined with support for up to 96GB of DDR5 memory versus 64GB on the MS-01, the MS-A2’s CPU configuration offers better overall headroom for demanding, sustained workstation use.

Minisforum MS-A2 vs MS-01 – Graphics and Processing Power Compared

Although the Minisforum MS-01 and MS-A2 are positioned as compact workstations rather than gaming rigs, integrated graphics performance still plays a role in determining their suitability for visual workloads, media playback, and GPU-accelerated tasks. The MS-01 leverages Intel’s Iris Xe graphics, which includes 96 execution units running at up to 1.5GHz. The MS-A2, on the other hand, features AMD’s Radeon 610M — a lightweight RDNA2-based iGPU with 2 compute units operating at 2.2GHz. While the AMD GPU has a higher clock speed on paper, the significantly larger number of execution units in the Iris Xe gives the Intel system a considerable edge in real-world performance. In benchmarks such as the Steel Nomad Light test, the MS-01 consistently delivered higher frame rates and better render completion times, particularly during prolonged sequences that tax the GPU.

This performance advantage was also evident in media encoding and general GPU-accelerated workloads. Intel’s integrated graphics tend to benefit from better driver maturity, wider codec support (particularly for Quick Sync Video), and improved handling in professional apps with Intel-optimized pipelines. Users working in environments involving light 3D rendering, accelerated video encoding, or virtual display compositing are more likely to see stable and consistent results from the MS-01’s iGPU. However, it’s important to note that neither device is intended to replace a discrete GPU for high-end graphical workflows. Their iGPUs are best suited for media playback, multi-monitor output, light rendering tasks, and as fallback units for headless server use.

That said, the MS-A2 reclaims ground when it comes to video output capabilities. While the MS-01 supports HDMI 2.0 and DisplayPort 1.4a via USB4, the MS-A2 steps forward with HDMI 2.1 and DisplayPort 2.0 over Type-C. This enables support for up to 8K at 60Hz and 4K at 144Hz, offering tangible benefits for users who rely on ultra-high-resolution displays or high refresh rate monitors in productivity setups. Professionals in video editing, CAD work, or photography may find that this broader standard support gives the AMD model a longer shelf life as display technologies advance. In broader processing terms, the MS-A2’s superior CPU — the Ryzen 9 9955HX — delivers more overall compute performance, particularly in multi-threaded applications. But for users with GPU-reliant workloads or who value stability across legacy software environments, the MS-01’s Iris Xe graphics make a compelling case. Ultimately, choosing between the two comes down to workload distribution: CPU-heavy environments favor the MS-A2, while mixed or GPU-skewed tasks lean toward the MS-01.

Minisforum MS-01 vs MS-A2 – Conclusion and Verdict

After evaluating both systems across CPU architecture, internal connectivity, storage bandwidth, and thermal performance, it becomes clear that the Minisforum MS-01 and MS-A2 cater to slightly different segments of the same professional user base. The MS-01, despite being over a year old, still offers a well-balanced configuration with mature Intel performance, reliable thermal behavior, and excellent compatibility with existing Intel-optimized software. Its Intel Core i9-13900H processor delivers solid single-core performance and responsive handling in mixed-load scenarios, particularly when combined with Iris Xe graphics that outperform AMD’s 610M in general GPU-accelerated tasks. When paired with dual 10GbE SFP+ ports, 2.5GbE RJ45, and PCIe expansion, the MS-01 provides considerable functionality in a highly compact chassis — all at a more affordable starting price than its AMD counterpart.

However, the MS-A2’s specification gains are more than just incremental. It introduces a newer CPU platform with significantly higher multi-threaded performance, better storage throughput via triple PCIe 4.0 x4 M.2 slots, and wider memory support scaling up to 96GB at 5600MHz. These improvements position the A2 as a clear upgrade in raw compute potential. Enhanced display output support, including HDMI 2.1 and DP 2.0 over USB-C, adds flexibility for users deploying ultra-high-resolution or high-refresh-rate monitors in content creation, design, or data visualization environments. Furthermore, the updated internal cooling system — subtle in layout but effective in long-term thermal consistency — ensures the AMD-based system maintains sustained performance under extended workloads. While the MS-A2 demands a higher upfront investment, it delivers longer-term value for users running multi-threaded software stacks, high-speed storage arrays, or heavy virtual machine workloads. In essence, the MS-01 is still a dependable and well-priced workstation that meets the needs of a wide user base. But the MS-A2 redefines Minisforum’s performance ceiling with broader bandwidth, more compute power, and enhanced scalability. For users focused on future-proofing, heavier workloads, or maximizing hardware capability within a small form factor, the MS-A2 is the more capable — if more expensive — option. Your choice ultimately comes down to whether cost or capability is the higher priority in your deployment.

Jonsbo N10 NAS Case Review – A REAL M-ITX NAS Enclosure?

The Jonsbo N10 is a purpose-built NAS enclosure tailored for Mini-ITX builds that prioritizes a compact footprint, flash-based storage, and low-power operation. Announced at Computex 2025, the N10 represents a significant design departure from Jonsbo’s earlier N5 chassis by reducing overall dimensions to just 205mm in width and depth, and 108mm in height. This change reflects a broader trend in DIY NAS building—especially among users deploying SSD-only arrays or compact motherboards with embedded CPUs—who value minimal space usage without sacrificing component access or build quality. The enclosure supports up to four 2.5-inch SATA SSDs or HDDs mounted along its internal base, along with a FLEX 1U power supply (up to 150mm) and a low-profile CPU cooler not exceeding 38mm in height. Constructed from thick 3.3mm aluminum alloy panels and a 1.0mm steel interior frame, it offers durability alongside a neutral, industrial aesthetic that blends well in home and office environments. Given the increasing popularity of MITX NAS boards from brands like Topton and CWWK, which often include soldered CPUs and compact layouts, the Jonsbo N10 enters the market as a focused option for builders who need efficient thermal performance, portability, and enough internal expansion to support a hybrid SSD/M.2 architecture in a space-conscious package.

Jonsbo N10 NAS Enclosure Review – Quick Conclusion

The Jonsbo N10 is a compact, purpose-built Mini-ITX NAS enclosure designed for users prioritizing SSD-based storage in a low-power, space-efficient build. With a footprint of just 205mm square and 108mm tall, it offers four 2.5-inch drive bays, FLEX PSU support, and a solid aluminum-steel construction that balances durability with minimalism. Its layout is well-suited for embedded CPU boards and hybrid storage configurations, but tight internal spacing, a 38mm CPU cooler height limit, and the lack of PCIe card support require careful component selection. While cooling is handled by two built-in 40mm fans and ventilation across multiple panels, airflow in the upper cavity remains passive and somewhat restricted—posing thermal challenges for high-performance CPUs or 10GbE NICs. Setup is straightforward, though users must manually route all SATA data and power cables, as no backplane is included. The inclusion of helpful accessories such as a Molex-to-SATA adapter and magnetic top panel adds value, and the minimalist I/O—with a single USB Type-C—reinforces its role as a headless NAS unit. Ultimately, the N10 is not a catch-all solution, but for users building SSD-centric NAS systems with efficient MITX boards, it offers a tightly focused and well-executed platform with a strong balance of features and size.

Jonsbo N10 NAS Enclosure Review – Case Design, Ventilation and Cooling

The exterior design of the Jonsbo N10 emphasizes minimalism and space efficiency. Measuring just 205mm wide, 205mm deep, and 108mm high, the case is almost a perfect cube in footprint, but with a shallow vertical profile that makes it easy to deploy on desks, shelves, or tight AV cabinets. The use of 1mm thick aluminum alloy on the outer panels not only provides a premium feel but also contributes to structural integrity without excessive weight.

Combined with the internal steel chassis, the enclosure remains sturdy under load while keeping its overall weight to just 1.6kg. From a visual standpoint, the clean lines and brushed finish—available in black or silver—are devoid of branding or unnecessary ornamentation, which suits its role as a discrete server or quiet storage box in professional or home setups.

Ventilation is a core part of the external layout, with venting present on nearly every surface of the chassis. Perforations on the side panels, rear, and base allow for passive air movement across internal components, helping to reduce thermal buildup. While the compact size limits the scope of airflow paths, Jonsbo has attempted to compensate by ensuring that each major face includes some form of ventilation.

The top panel, held in place magnetically, can be removed easily for additional airflow during installation or servicing. However, this panel itself includes no fan mounts or perforations, which may limit vertical heat dissipation unless the lid is removed or modded.

Cooling is primarily handled by two built-in 40mm x 20mm exhaust fans mounted on the rear panel, each rated at 5000 RPM. These fans are positioned to draw hot air away from the internal drive bay and motherboard area, effectively pulling air in through the side and base perforations and pushing it out the back.

While the fans are small, their high RPM ensures a reasonable volume of air is cycled through the chassis. During testing, this design produced moderate acoustic output—peaking at around 43-45 dBA at load when measured from the rear—and noise levels were generally acceptable for typical NAS operation, particularly with low-TDP motherboards and embedded CPUs.

That said, airflow through the top cavity of the enclosure is limited. While the base panel and lower chamber benefit from fan-assisted cooling directed over the SSDs and PSU, the upper portion—where the CPU cooler and any on-board NICs are located—relies entirely on passive convection.

This can lead to hot air stagnation around components like 10GbE controllers or active M.2 heatsinks, particularly in long uptime scenarios. In your testing, surface temperatures on the top panel reached 31–33°C after 24 hours of deployment, with internals climbing higher toward 55–56°C, especially around passive heatsinks with limited surrounding airflow.

The absence of additional fan mounting options or top-mounted exhaust fans means users have little room to expand the cooling setup. While some users may consider modding the top panel to add extra fans or mesh inserts, the stock configuration offers no support for such upgrades.

This makes thermal planning crucial, especially for users deploying more powerful CPUs like Intel’s i5-1240P or using motherboards with multiple onboard NVMe drives and high-speed networking. For more passive deployments, like those with low-power N305 or N355 CPUs and minimal drive activity, the default setup should be sufficient—though tight airflow margins should always be considered during build planning.

Jonsbo N10 NAS Enclosure Review – Internal Design

Internally, the Jonsbo N10 is laid out to support only the essentials, reflecting its role as a NAS-first chassis with limited internal expansion. The Mini-ITX motherboard tray sits centrally within the lower half of the enclosure, flanked on one side by the FLEX PSU bracket and on the other by the horizontal drive cage. Despite the symmetrical exterior, internal space is tightly constrained, and components must be carefully selected and installed in a deliberate sequence to avoid obstructing airflow or cabling paths.

The steel frame keeps the motherboard tray stable, but there’s little clearance between installed components, which becomes immediately apparent when routing power and SATA data cables across the system. Most of the case’s internal volume is claimed by either the drive cage or power supply, leaving minimal open airspace.

The four 2.5-inch drive bays are arranged in a single, fixed cage at the base of the unit. This cage does not feature any kind of backplane or hot-swap system—instead, users must manually screw each SSD into place using traditional mounting trays. Drives are accessed from the underside of the top panel after removing the magnetic lid, and their power/data cabling must be routed individually.

In small builds, this can quickly become a challenge. The case includes a Molex-to-SATA power adapter, which is a thoughtful addition for budget FLEX PSUs that lack four dedicated SATA power leads. However, data cable management remains the user’s responsibility. In builds using motherboards without breakout SATA connectors (such as SFF-8643 or SlimSAS), this results in a dense bundle of SATA leads running through an already cramped enclosure.

Clearance around the CPU socket is equally limited. The N10 supports CPU coolers up to 38mm in height, restricting users to ultra-low-profile models. This makes it well-suited for embedded CPU motherboards like the CWWK N150 or N355, which come with passive or ball-bearing heatsinks under 30mm.

However, builders looking to use socketed CPUs like the i5-1240P will need to carefully select compatible coolers and be mindful of airflow choke points. There is no room for PCIe devices internally, and although some MITX boards have slots, they are effectively unusable due to chassis constraints. Any notion of using riser cards or external PCIe breakouts (such as M.2 to OCuLink) is largely impractical within this case’s physical limits.

Connectivity on the Jonsbo N10 is intentionally minimal. The front I/O panel includes a single USB Type-C port positioned on the top-right edge of the chassis, routed internally via a standard front-panel header. There are no additional USB-A ports, audio jacks, or buttons present, in keeping with the case’s clean exterior aesthetic.

While this simplicity reinforces the N10’s focus as a headless or remote-managed NAS system, it does reduce options for users who might want to connect external drives, peripherals, or configure the system locally without reaching behind the unit. Builders relying on initial direct access may need to route peripheral cabling through the rear motherboard I/O or temporarily remove the top lid for setup.

The power supply format supported is strictly FLEX 1U, with units up to 150mm in length permitted. This rear-mounted PSU bracket is placed above the motherboard tray and next to the SSD cage, and the power supply’s fan helps assist with rear airflow in conjunction with the two pre-installed 40mm exhaust fans.

While FLEX PSUs are well-suited to compact enclosures, they can be noisy under load and tend to cost more than SFX or ATX equivalents—especially if aiming for 80+ Gold or higher efficiency ratings. The internal wiring must be routed carefully due to spatial limitations, and although the case does include a Molex-to-SATA power adapter, it does not include any SATA data cables, which users must supply themselves. PSU airflow is indirectly beneficial to nearby components, but cooling requirements should be factored into PSU selection to avoid thermal bottlenecks.

The N10’s primary storage capability comes from its four internal 2.5-inch drive bays. Positioned in a fixed steel cage, the bays are arranged horizontally and mounted via screws without any vibration dampening or tool-less features. As noted earlier, there is no backplane, so each drive requires a dedicated SATA data and power cable, which must be routed manually through tight internal spaces.

While the design clearly targets SSD usage due to thermal and vibration limitations, there is potential for 2.5-inch HDDs as well—though builders should be cautious of heat and noise. Some modders may consider fitting up to two 3.5-inch drives with minor modifications, but this would require bypassing manufacturer recommendations and limits compatibility to 8TB drives or smaller due to physical height constraints.

When paired with modern MITX boards featuring multiple onboard M.2 slots, the N10 can accommodate hybrid storage setups—though again, thermal planning remains crucial.

The Jonsbo N10 delivers on its objective: to offer a compact, purpose-built NAS enclosure for Mini-ITX systems focused on SSD-based storage. It embraces the growing trend of low-power, embedded CPU platforms and caters directly to users building quiet, energy-efficient NAS devices for tasks like media serving, remote backups, or personal cloud storage. Its clean exterior design, robust aluminum-steel construction, and compact footprint make it appealing for constrained environments or unobtrusive desktop deployment. The inclusion of pre-installed fans, a Type-C front I/O, and even minor accessories like a Molex-to-SATA adapter add value to the out-of-box experience. However, its internal layout requires deliberate component choice and build planning due to significant space limitations and tight thermal margins.

While not designed for broad flexibility, the N10 excels in its niche. There is no support for PCIe add-ons or active top-panel cooling, and the absence of hot-swap bays or bundled SATA data cables may frustrate some users expecting turnkey solutions. That said, for those familiar with small form factor NAS building, these limitations are expected trade-offs for a case that prioritizes minimalism and focused utility. As pre-built NAS units continue to integrate soldered CPUs and non-upgradable memory, enclosures like the N10 offer a rare chance for builders to retain full control over their hardware stack—provided they’re willing to work within the tight confines of the design. In short, the N10 is not for everyone, but for those building compact SSD-focused NAS systems, it strikes a well-executed balance between form, function, and footprint.

Review of the UGREEN NAS UPS – Is the US3000 120W UPS Any Good?

The UGREEN US3000 is a 120 W DC uninterruptible power supply developed specifically for UGREEN NAS devices that rely on an external DC power brick. Unlike conventional UPS systems that convert AC to DC, this model outputs direct 12 V DC power with a zero-second transfer time, ensuring there is no interruption during a power loss. It is equipped with a 12,000 mAh lithium-ion battery pack made up of four 3000 mAh cells, providing a rated energy of 43.2 Wh and up to around ten minutes of backup time depending on workload. Measuring 120.6 × 80.5 × 29.6 mm and weighing approximately 439 g, the US3000 is compact enough for desktop environments where space is limited. Beyond supplying short-term emergency power, it integrates with UGOS Pro software via a USB communication cable, allowing automated shutdown, timed standby, and restart once power is restored. This focus on seamless hardware and software compatibility makes the US3000 notable for users running UGREEN NAS systems that need to mitigate risks of data corruption caused by sudden outages.

UGREEN US3000 UPS Review – Quick Conclusion

The UGREEN US3000 is a purpose-built DC UPS that prioritizes seamless integration with UGREEN NAS systems over broad flexibility. Its compact aluminum chassis houses a 12,000 mAh lithium-ion battery pack capable of delivering 120 W output with zero-second transfer time, ensuring that a connected NAS continues running long enough to perform a safe shutdown.

Why the UGREEN US3000 UPS is Important/Interesting

Uninterruptible power supplies are not new, but most consumer models are designed for general computing and rely on bulky lead-acid batteries with AC pass-through. The UGREEN US3000 differs by offering a DC-to-DC solution that matches the external power design of UGREEN NAS units. This means it eliminates the inefficiency of double conversion and avoids the audible transfer delays that can occur with traditional UPS hardware. With a 120 W output ceiling, it is tailored for single-device use rather than multiple systems, but that specificity ensures closer integration with the NAS’s power and shutdown controls. From a technical perspective, its lithium-ion battery pack offers greater energy density than lead-acid, allowing the device to remain compact while still covering several minutes of safe system operation during an outage.

The importance of this UPS becomes clearer when examining how it interacts with UGOS Pro. Unlike generic solutions, the US3000 communicates directly with the NAS operating system via a USB connection, exposing monitoring and automation options in the control panel. Users can configure automatic shutdown after a set period, trigger standby to conserve remaining charge, or enable auto-restart once mains power returns. These features are not just convenient but directly address the risks of corrupted writes, incomplete backups, or damaged RAID arrays during sudden power loss. Given that UGREEN NAS systems are designed for small offices and home use, where environments may not include larger enterprise-grade UPS equipment, the US3000 effectively bridges that gap by offering a purpose-built, compact, and integrated safeguard.

UGREEN US3000 UPS Review – Design

The UGREEN US3000 follows a compact, rectangular form factor with dimensions of 120.6 mm in length, 80.5 mm in width, and 29.6 mm in thickness. Its weight of just under 440 g makes it relatively lightweight for a UPS, reflecting its focus on portability and single-device deployment rather than large-scale power protection. The outer chassis is made from anodized and sandblasted aluminum alloy, which gives it improved durability compared with plastic housings and also aids in passive heat dissipation. The choice of materials ensures a consistent finish that aligns visually with UGREEN’s NAS enclosures, providing an integrated appearance when the two devices are used together on a desktop.

Connectivity is handled entirely through DC and USB ports positioned on a single side of the device. The panel includes a DC input, a DC output, a USB-C port for data communication, and a power button. The fixed DC cable has a length of approximately 28 cm, while the included USB-A to USB-C cable measures around 53 cm, allowing flexible placement next to a NAS system without excess cabling. Each port and control is clearly labeled with printed icons, reducing the likelihood of incorrect setup. Unlike conventional UPS systems that feature multiple AC sockets, the US3000 focuses on a single dedicated output, reflecting its intended role as a companion unit for UGREEN NAS models rather than a general-purpose UPS.

The packaging of the device mirrors UGREEN’s approach with its NAS line, offering clear product imagery and specification highlights on the box exterior. Inside, the unit is provided with a base stand for stable positioning, the aforementioned data cable, and basic documentation. This is a minimalist package compared to conventional UPS units, which often include multiple adaptors or accessories, but the streamlined approach ensures that setup remains straightforward for the intended NAS integration. The inclusion of a stand is particularly useful given the slim design, as it helps keep the UPS stable in vertical placement while maintaining airflow around the chassis.

From a design perspective, the emphasis is on simplicity and integration rather than flexibility. The device does not feature multiple voltage outputs, nor does it support powering unrelated devices such as routers or switches. Instead, its DC pass-through design, small footprint, and single-device orientation mark it as a specialized tool. This aligns with UGREEN’s approach of building a controlled ecosystem around its NAS systems, where accessories are engineered for direct compatibility. The US3000 therefore sits between consumer-grade battery packs and enterprise UPS units, offering a focused solution that fits into a narrow but clearly defined usage scenario.

UGREEN US3000 UPS Review – Internal Power Design

Inside the UGREEN US3000 is a straightforward but carefully constructed layout built around a 12,000 mAh lithium-ion battery pack. The pack consists of four SunPower INR18650-3000 cells, each rated at 3000 mAh and 11.1 Wh, connected in series to deliver a combined rated energy of 43.2 Wh at 14.4 V. The cells are wrapped in foam insulation and secured with adhesive to minimize movement, with spot-welded nickel strips linking them. Additional barley paper insulation is applied around the terminals for added protection. This design choice allows the UPS to maintain compact dimensions while ensuring sufficient runtime for controlled NAS shutdowns.

Battery management is handled by a Chipsea CBM8580KV6NT protection IC. This chip monitors voltage, current, and temperature across the pack, ensuring safe charging and discharge cycles. It communicates with the system host via SMBus 3.1, which enables the UPS to relay real-time status to the NAS when connected through USB. Supporting components include current sense resistors, thermistors, and MOSFETs for switching and power regulation. Together, these ensure not only that the battery operates safely but also that the UPS can reliably deliver 120 W maximum output without voltage instability.

Voltage conversion is performed by a dual-stage arrangement. A Texas Instruments TPS55289 synchronous buck-boost converter handles a wide input range up to 30 V and can output between 0.8 V and 22 V. Alongside this, a SouthChip SC8002 synchronous buck controller manages current limiting and efficiency across dual channels. Power MOSFETs from CR MICRO and NCEPower are used for pass-through control and output switching, while a GigaDevice GD32F303RCT6 Cortex-M4 microcontroller coordinates the overall system, including communication with the NAS. Passive cooling, adhesive reinforcement on inductors and capacitors, and fuses at both input and battery ends further underline the design focus on stability and safety.

UGREEN US3000 UPS Review – Testing with UGREEN NASync Systems

To evaluate the UGREEN US3000, three operational scenarios were simulated: immediate power loss with continued operation, automatic shutdown under UPS control, and timed shutdown with automatic restart when power returned. In each case, the NAS was connected to the UPS using both the DC input and USB communication cable to ensure full integration with UGOS Pro. The first test involved disconnecting mains power to replicate an outage. The NAS continued running without interruption, with the transfer to battery occurring instantly. System logs registered the event in under two seconds, and normal file access, media playback, and downloads remained available until the battery level dropped to the configured threshold.

In the second test, the system was configured to shut down automatically as soon as the UPS switched to battery mode. Once power was removed, the NAS immediately began its shutdown process. This test showed that the UPS integration with UGOS Pro allowed a fast and orderly shutdown sequence, preventing data corruption or incomplete writes. The reaction time was near instantaneous, and the system was powered down safely without user intervention. This mode may be best suited for environments where uptime during an outage is less critical than ensuring rapid data protection.

A third test focused on timed shutdown, with the UPS set to keep the NAS running for five minutes before initiating a safe power-off. Once mains power was disconnected, the NAS continued operating for the specified period, then shut down as configured. After power was restored, the UPS automatically triggered a restart of the NAS, returning it to full operation within a few minutes. This confirmed the UPS’s ability not only to handle outages but also to manage recovery without manual restart, which is beneficial for users who may not be present during a power failure.

During all tests, the device’s limitations became apparent. With a 120 W maximum output and battery capacity limited to 43.2 Wh, it cannot sustain extended operation. Its role is restricted to ensuring controlled shutdowns and short bridging periods rather than providing long-term backup. Furthermore, it supports only one NAS system via DC pass-through, so it cannot protect additional hardware such as routers or switches. Nevertheless, within its defined parameters, the UPS consistently delivered seamless transitions and executed software-triggered events reliably, confirming that its functionality matches its intended scope.

UGREEN US3000 UPS Review – Conclusion & Verdict

The UGREEN US3000 fills a specific role: protecting UGREEN NAS devices from sudden power loss. Its design avoids the bulk and inefficiency of conventional AC-based UPS units by delivering DC pass-through power with zero transfer time. In practice, it provides just enough runtime for the NAS to perform a controlled shutdown, while its software integration ensures automation of both power-off and restart processes. With lithium-ion cells, a compact aluminum chassis, and close alignment with UGOS Pro features, it is engineered as a dedicated accessory rather than a universal power backup solution.

As a result, its usefulness is limited to scenarios where a single UGREEN NAS is the priority. It does not offer multiple outputs or extended backup duration, making it unsuitable for wider network coverage or enterprise requirements. Instead, the US3000 should be viewed as a narrowly focused safeguard that addresses one problem reliably: preventing data corruption and incomplete writes during outages. For users within the UGREEN ecosystem, it is an effective solution, but for broader applications, its scope remains intentionally constrained.

Get Graphics Drivers and Hardware Transcoding BACK for Plex/Jellyfin/Emby on your Synology NAS

Note – the video on this fix will be published soon and I will update this article with images ASAP.

Synology’s 2025 refresh brought the DS225+ and DS425+ with the familiar Intel Celeron J4125, but it also quietly removed the kernel graphics driver support that Plex, Jellyfin, and Emby use for hardware transcoding of H.264 and HEVC. This guide explains what changed, why it matters for real-world streaming, and how you can restore GPU-accelerated transcoding on these models using an unofficial SSH method shared by the community. If you rely on your NAS to reshape 4K or high bitrate files for phones, tablets, hotel TVs, or limited connections, this walkthrough will help you get that efficiency back.

IMPORTANT – Massive credit to RROrg group over on Github for ‘cracking the nut’ on this with their latest repo HERE 

Additionally, credit to Luka @ Blackvoid, who made this great article, covered this first and gave me permission to use his guide here and in my upcoming video. Read his article HERE

What Happened to Hardware Transcoding on the Synology 2025 NAS, and Why Is This a Problem

When Synology launched the 2025 “x25” lineup, users expected a minor refresh of familiar models like the DS225+ and DS425+. Instead, they discovered that Synology had removed the i915 graphics driver from DSM, effectively disabling hardware transcoding on the Intel Celeron J4125 CPU. This meant that Plex, Jellyfin, and Emby could no longer tap into the iGPU’s Quick Sync Video capabilities. Synology confirmed the change in support tickets, explaining that both H.264 (AVC) and H.265 (HEVC) transcoding had been deliberately blocked at the kernel driver level. The company cited licensing costs for HEVC, even though AVC is license-free, and argued that most client devices already support native playback. The earliest and longest discucssions on this topic are HERE on this Plex Forum thread.

The result is a significant downgrade for users who bought these models expecting the same multimedia performance as their predecessors. Instead of 10–20% CPU usage during hardware-accelerated transcoding, users now see 80–100% CPU utilization when reshaping video on the fly. For remote streaming, converting 4K to 1080p or 720p becomes slow, inefficient, and often unworkable. This change undermines the value proposition of the J4125 platform and leaves Plex and Jellyfin users with hardware that is technically capable but artificially restricted, creating frustration across the Synology community.

Disclaimer: This Is Unofficial – Know the Risks!

Before diving into the workaround, it is important to understand that this method is not supported by Synology and involves altering core system modules via SSH. These steps rely on community-compiled drivers and are provided “as is,” without warranty. Making changes at the kernel level can cause instability, break after DSM updates, or in the worst case, lead to data loss if mistakes are made. You should always keep verified backups of your data before proceeding, and only attempt this if you are comfortable working with the command line and root-level access. Proceed entirely at your own risk.

Step By Step Guide to Get J41225  Graphics Drivers Hardware Transcoding Back

1. Download the Source Code

   • Go to Dave Russell’s GitHub repo (007revad) and download the Source Code (.zip) for the graphics driver fix.

   • 

   • Do not unpack the archive on your computer.

2. Create a Folder on Your NAS

   • Log into DSM and create a new Shared Folder (e.g. scripts) on your main volume.

   • 

   • Make sure your DSM account has full access, since root privileges will be needed later.

3. Upload the Archive

   • Use File Station or SMB to upload the .zip file into the new scripts shared folder.

   • 

   • Once uploaded, extract it on the NAS by right-clicking and selecting Extract Here.

   • 

   • If extraction creates subfolders, move the relevant script files (such as transcode_4_x25.sh) directly into the main scripts directory for easier referencing.

   • 

4. Create a Scheduled Task

   • Open Control Panel > Task Scheduler.

   • 

   • Select Create > Triggered Task > User-defined Script.

   • 

   • Give the task a name (e.g. Synogfx).

   • 

   • Set the User to root.

   • Set the event to Boot-up so the script runs every time the NAS restarts.

   

5. Point to the Script

   • In the task settings, paste the full path to the script file, for example:

     sh /volume1/scripts/transcode_4_x25.sh


   • If unsure, right-click the .sh file in File Station, select Properties, and copy the full directory path.

   • 

6. Confirm and Save

   • DSM will warn you about using root and non-standard scripts. Acknowledge this and proceed.

   • 

   • Enter your DSM admin password when prompted.

   • The scheduled task will now appear in the list.

   • 

7. Run the Script

   • Right-click the new task and select Run to execute it immediately.

   • 

   • Optionally, reboot your NAS to confirm that the driver loads automatically on startup.

   • 

8. Verify Hardware Transcoding

   • Open Plex (or Jellyfin/Emby) and play a file requiring transcoding.

   • 

   • Check playback statistics: you should now see HW (hardware transcoding) instead of CPU-only usage.

• 

Conclusion

Synology’s decision to remove iGPU drivers from the 2025 DS225+ and DS425+ left many users frustrated, especially those who rely on Plex or Jellyfin for remote streaming. While the company cites licensing costs and client-side decoding as justification, the hardware itself remains fully capable of transcoding. Thanks to community-driven efforts, it is possible to re-enable Quick Sync on these models with an SSH-based workaround. This fix restores the efficiency and functionality users expected, though it comes with risks and requires maintenance after reboots. For multimedia enthusiasts who value hardware transcoding, this unofficial solution may be the only way to unlock the true potential of these NAS systems.

fnOS Beta Review – Should You Keep an eye on Feiniu NAS OS?

Feiniu Private Cloud, better known by its system name fnOS, is a closed-source Chinese NAS operating system currently in public beta. Developed by a small team of self-described NAS enthusiasts, fnOS is marketed as a “genuinely free” NAS solution for domestic users in China and is designed to run on standard x86 PC and NAS hardware. It offers media management tools, AI-powered photo categorization, Docker container support, RAID configurations, and an app ecosystem — all within a graphical user interface that resembles several other recent Chinese NAS solutions. The system is rooted in a Debian-based Linux distribution and aims to provide plug-and-play functionality for users seeking an alternative to more established platforms like DSM, QTS, or TrueNAS.

However, fnOS arrives with notable caveats. As a closed-source system with minimal public documentation, there is currently no way to verify its internal processes, telemetry behaviour, or long-term data integrity protections. Moreover, its security architecture lacks advanced features like two-factor authentication, iSCSi, ZFS or hardened remote access protocols that have fast become an industry standard of many other NAS software options in the market.

Language support outside of Simplified Chinese is also not fully implemented, creating potential navigation barriers for international users. While the interface and features may seem appealing on the surface, fnOS is still in a formative stage — and with it come the usual risks of data loss, unpatched vulnerabilities, and limited user support. As this review will show, fnOS represents a curious blend of innovation, imitation, and potential. But its closed nature, beta status, and regionally restricted development raise several questions about its readiness for use beyond a testing environment.

Disclaimer for Users Considering fnOS Right Now

Anyone considering the use of Feiniu Private Cloud (fnOS) should do so with full awareness of the risks inherent in testing an early-stage, closed-source operating system. Although the software is being actively developed and presents a relatively complete GUI with numerous features, it remains in public beta. The system has not yet undergone broad public scrutiny, independent code audits, or transparent vulnerability testing, making its real-world reliability uncertain. The developers themselves have issued formal cautions, explicitly stating that the beta version may cause system crashes, compatibility problems, or data loss. Users should avoid deploying fnOS on primary NAS systems, in business environments, or on any hardware storing valuable or irreplaceable data. Thorough offline backups should be made prior to installation, and any testing should be performed in a non-critical sandbox environment. The system’s UI is currently presented almost entirely in Simplified Chinese, with no comprehensive English language support available at this stage. Translation tools such as Google Lens or Microsoft Edge’s built-in translation functions may offer partial usability, but navigation and configuration still present challenges for non-Chinese speakers.

Security considerations are especially important. fnOS lacks industry-standard safeguards such as two-factor authentication, secure portal client tools, and deeper role-based access controls. There is also no detailed public disclosure about how the system handles network traffic, cloud synchronization, or metadata collection, which is a point of concern given its integration with AI services and remote access features. At present, it is unclear whether any telemetry or user analytics are sent back to the developers, and the absence of source code prevents community verification. In summary, fnOS should be treated as experimental software. While it may offer a glimpse into emerging trends in the Chinese NAS market and present intriguing ideas around media organization and local AI integration, users must approach it with caution and a strong understanding of the security and stability limitations that accompany early-stage, proprietary platforms.

Design and UI

The user interface of fnOS is visually structured and attempts to emulate the layout seen in many modern NAS operating systems, with clear menu segmentation and app-like modularity. Upon installation, users are presented with a desktop-style environment that includes access to system configuration, storage management, multimedia tools, and containerized applications.

Navigation is conducted through a web browser, and the interface features icon-driven panels that mirror the design language of platforms like DSM (Synology) or QTS (QNAP), albeit with some localization quirks. Despite its early-stage development, the UI demonstrates a coherent structure that is functional, if not yet polished.

However, the current implementation suffers from language accessibility issues. The interface is only available in Simplified Chinese, and efforts to translate the interface using automated tools like Google Translate are mostly ineffective, as it relies on dynamic rendering elements that these tools cannot parse. Microsoft Edge’s translation feature performs better but still results in fragmented grammar and partially translated system prompts. This creates a substantial usability barrier for non-Chinese speakers, particularly when trying to configure advanced settings such as RAID arrays, user permissions, or application environments.

In terms of responsiveness and performance, the UI behaves relatively smoothly even on modest hardware. Common actions such as creating storage volumes, configuring shares, or launching apps execute without visible lag. While some buttons and system prompts may feel incomplete or imprecise due to beta status, core layout principles like logical menu placement and centralized settings are well applied. The overall experience suggests that while fnOS is clearly designed with user convenience in mind, it is not yet refined enough for a wide international audience.

Services and Features

fnOS provides a wide array of features targeting home media consumption, local data storage, and remote accessibility. One of its most promoted capabilities is its media handling, with built-in applications for organizing video, music, and photos. The system includes automatic metadata scraping for movies and TV shows, AI-driven facial and object recognition for photo libraries, and a basic music playback utility.

These media apps mimic the functionality of solutions like Plex or Jellyfin, offering poster walls, subtitle downloads, and transcoding options. However, it should be noted that many of the multimedia tools are proprietary adaptations or containers wrapping existing open-source tools rather than purpose-built innovations.

The system also integrates AI-driven services at the local level. The photo application includes features like character-based photo aggregation and image search via text input. Users can select from multiple AI models depending on resource availability and desired recognition accuracy, though it’s not entirely clear whether these models run exclusively offline or leverage external processing. While the integration appears functional, it is not yet well-documented, and the practical use cases are still limited by the interface’s language barriers and overall beta stability.

fnOS includes standard NAS features such as RAID configuration (supporting levels like RAID 0, 1, and 5), SSD caching, and storage expansion. It uses BTRFS or EXT4 as file system options, with support for snapshot creation on BTRFS volumes. Network protocols such as SMB3, NFS, FTP, and WebDAV are available, with multi-channel SMB enabled by default.

There is also a built-in file manager allowing basic copy, move, download, and sharing functions, including time-limited and password-protected links. While ZFS is not supported, the storage tools provided are sufficient for basic to intermediate users familiar with RAID and shared folder management.

The included App Center is container-based and supports various community and utility applications. Notable entries include Qbittorrent, Jellyfin, Transmission, Alist, Portainer, and Chromium, alongside more region-specific tools like 115 Network Disk and Baidu Cloud integration.

The application store largely reflects popular Dockerized solutions and offers minimal documentation on integration specifics. fnOS also includes a rudimentary virtual machine manager, which allows for Windows VM creation via ISO files, though functionality is basic.

Backup tools support both local folder sync and remote NAS replication, but third-party cloud sync is limited in scope and likely tied to domestic Chinese services.

 

Pros and Cons of fnOS?

One of the most notable strengths of fnOS is its broad feature coverage for a beta-stage NAS operating system. Despite being early in its development, it includes many of the core functions expected from a modern NAS platform: multi-tiered RAID support, snapshot capabilities (via BTRFS), Docker-based application hosting, multimedia indexing, and even virtual machine support.

For home users interested in media storage, the built-in tools for automatic metadata scraping and subtitle acquisition, combined with basic transcoding support, make it a practical solution for centralized media access — particularly when paired with a TV interface or mobile app.

The inclusion of AI-powered image recognition and customizable AI models in the photo management application is another area where fnOS differentiates itself. Users can configure local facial and object recognition models to assist in organizing large photo libraries, and even perform text-based image searches. While this isn’t entirely unique in the NAS market, the ability to select from different AI models and the implementation of geolocation tagging and facial clustering demonstrates that the development team is thinking beyond basic storage functionality. It suggests potential for future expansion into smart content management if development continues at pace.

However, fnOS also presents several clear drawbacks. Security remains underdeveloped, with no support for two-factor authentication, no publicly available information on encryption practices, and limited visibility into how data is handled or transmitted over the network.

While SSL certificates and basic firewall tools are present, the absence of fine-grained user permission structures or auditing functionality makes it unsuitable for multi-user environments or deployments where data privacy is a primary concern. Additionally, remote access services built into fnOS are proprietary and undocumented, which raises further questions for users concerned about trust and control over their network.

Another key limitation is the lack of proper language support and international readiness. At the time of writing, the UI is only available in Simplified Chinese, and the developers have not confirmed a timeline for multilingual support, also highlighting that this will be phased into a paid/commercial use version. This, combined with limited documentation and forum discussion outside of Chinese-speaking communities, makes troubleshooting and adoption by non-Chinese users significantly more difficult. Moreover, as a closed-source system, fnOS cannot benefit from the auditing, forking, and community patching practices that open-source NAS platforms rely on to maintain user trust and long-term sustainability.

Conclusion and Verdict of fnOS NAS Software

fnOS represents an ambitious attempt to build a full-featured, home-friendly NAS operating system from the ground up, targeting a domestic Chinese audience first and foremost. Its functionality is surprisingly broad for a beta, covering storage management, AI-powered media organization, Docker app deployment, and local VM hosting. However, its closed-source nature, limited language support, and undeveloped security framework make it unsuitable for deployment outside controlled test environments. For users within China who are technically confident, aware of the risks, and seeking a free, self-managed solution, fnOS may have appeal. For international users, particularly those prioritizing transparency, privacy, or robust security, fnOS remains a curiosity—not yet a contender.

UniFi MASSIVELY Scale up their NAS Portfolio with the UNAS Pro 8, UNAS Pro 4, UNAS 4 and UNAS 2

Note, the UNAS Pro 2 is NOW LIVE on the UniFi Store . The UNAS 4, UNAS Pro 4 and UNAS Pro 8 are now in the site, but are not available till October.

Ubiquiti is preparing to significantly broaden its NAS product line in late 2025 with the introduction of four new systems under the UNAS branding. The new lineup follows the launch of the original UNAS Pro in 2024, which gained attention as a low-cost, seven-bay rackmount appliance that introduced UniFi into the NAS sector. With the release of the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8, the company is moving into what it describes as its “phase two” of NAS development, aiming to cover both desktop and rackmount form factors while integrating closely with the wider UniFi ecosystem. This expansion arrives at a time when established NAS vendors are tightening drive compatibility and raising prices, leaving a gap for alternatives that emphasise affordability, simplified deployment, and ecosystem consistency.

The UNAS Pro 8 NAS

4-Core ARM, 16GB RAM, 3x 10GbE, 8x SATA Bays, 2x M.2 Bays (trays required), Redundant PSU (2nd Sold Seperately) $799 – HERE

The UNAS Pro 8 will serve as the top-end model of the range, positioned in a 2U rackmount chassis and built to deliver higher capacity and redundancy. It features eight front-facing 2.5″/3.5″ SATA bays alongside two rear-mounted M.2 NVMe slots, accessible through modular trays.

The Pro 8 is powered by a quad-core ARM Cortex-A57 processor running at 1.7 GHz and paired with 16 GB of LPDDR4 memory. Unlike many entry-level ARM systems, the Pro 8 includes three 10-gigabit network interfaces: two SFP+ and one RJ45 supporting multi-gig speeds down to 100 MbE. Redundant hot-swappable 550W PSUs are supported, though only one is included by default, with seamless failover tested successfully under load.

The system uses SGCC steel for the enclosure, weighs 11.5 kg, and includes rack rails in the box, a detail rarely seen in turnkey solutions. Performance tests have demonstrated sequential reads close to 850 MB/s on HDDs in RAID 5, with expectations of saturating a 10GbE link when using SSDs or RAID 0.

The UNAS 2 NAS

4-Core ARM, 4GB RAM, 1X 2.5GbE PoE+++, 2x SATA Bays, Power Over Ethernet delivery (PoE+++ Adapter Included) $199 – HERE

At the opposite end of the spectrum is the UNAS 2, UniFi’s smallest NAS to date. This desktop unit measures just 13.5 x 12.9 x 22.37 cm and weighs 1.3 kg, with a polycarbonate chassis designed to keep cost and weight down.

The device supports two 3.5″ SATA drives housed in a shared tray, a design that requires both drives to be removed together and does not permit hot-swapping. This approach raises concerns about handling healthy drives during replacement but reduces the mechanical complexity of the system.

The UNAS 2 runs on a quad-core ARM Cortex-A55 at 1.7 GHz with 4 GB of LPDDR4 memory. Networking is provided by a single 2.5 GbE RJ45 port, which also delivers PoE++ power, with a maximum system budget of 60W (52W for drives). A 60W PoE++ injector is included for users without a suitable switch. A 1.47-inch colour LCM display on the front provides status updates, though it is non-interactive. A USB-C port rated at 5 Gbps adds external storage capability, addressing an omission noted in the original UNAS Pro, but it does not support UPS integration or networking adapters.

The UNAS Pro 4 NAS

4-Core ARM, 16GB RAM, 10GbE, 4x SATA Bays, 2x M.2 Bays (trays required), Redundant PSU (2nd Sold Seperately) $499 – HERE

Between these two extremes sits the UNAS Pro 4, a 1U rackmount unit designed for users who want the resilience of redundant PSUs and NVMe support without committing to an eight-bay chassis.

It includes four SATA bays and two M.2 NVMe slots, sharing the same ARM Cortex-A57 CPU and 16 GB of memory as the Pro 8. Like its larger counterpart, it is built for rack environments where redundancy and compact form factor are key priorities.

While exact dimensions and weight have not yet been confirmed (with the UNAS 2 and UNAS Pro 8 being the main focus of this new launch), the design is expected to follow Ubiquiti’s established rackmount conventions. Its specification profile makes it an option for smaller businesses or branch offices that need rack integration but do not require the capacity of an eight-bay system.

Category	Specification
Form Factor	Rackmount NAS (1U)

The UNAS 4, meanwhile, extends the desktop line and mirrors the design philosophy of the UNAS 2 but doubles the bay count.

It provides four 3.5″ SATA bays along with two M.2 slots, making it the only desktop model in the range to support NVMe caching or tiered storage.

It retains the same ARM Cortex-A55 CPU and 4 GB of fixed memory as the UNAS 2, positioning it as a modest but slightly more versatile desktop option.

Like the smaller model, it uses PoE+++ for power delivery and 2.5 GbE for connectivity, though it remains unconfirmed whether it will also include a secondary network interface for failover or link aggregation. As with other desktop models, the chassis is constructed from polycarbonate, with compact dimensions intended for office or home use rather than data centre deployment.

UniFi Drive 3.3 Update?

Alongside the hardware announcements, UniFi will also release UniFi Drive 3.3, a major update to its NAS management software.

This version introduces expanded RAID configuration options, broader support for third-party cloud platforms, enhanced fan control, and improved analytical tools for monitoring system health and performance.

Snapshots and backups remain central features, with cloud and LAN targets supported, while the update also improves scheduling flexibility and introduces additional reporting features.

Although iSCSI remains absent, UniFi Drive continues to mature from the limited platform released with the first UNAS Pro, and the 3.3 update is expected to improve usability across the entire new range.

The introduction of these four models demonstrates Ubiquiti’s intent to build a full family of NAS solutions rather than rely on a single experimental release. By offering both rackmount and desktop systems at varying capacities, the company is positioning itself to compete more directly with established NAS vendors, albeit with a more streamlined and ecosystem-focused approach. The UNAS 2 and UNAS 4 are targeted primarily at existing UniFi users seeking simple storage that integrates seamlessly with PoE switches, while the Pro 4 and Pro 8 are built to appeal to businesses looking for redundancy, higher bay counts, and greater throughput. The use of ARM processors across the line reflects UniFi’s efficiency-first design, even though it places limits on heavy workloads such as virtualisation or multimedia transcoding.

Detailed performance reviews and comparisons of the new models are expected in the weeks ahead, assessing how each device performs within its target segment. Particular attention will focus on how the Pro units handle sustained 10GbE workloads with HDD and SSD configurations, how the PoE-driven desktop models cope with thermal and power constraints, and how UniFi Drive 3.3 stacks up against more mature operating systems. With Ubiquiti steadily fleshing out its NAS portfolio one year on from the first UNAS Pro, the company’s ability to deliver consistent updates and address early hardware and software limitations will determine whether it can establish a lasting position in the NAS market.

The UniFi UNAS Pro 8 NAS Review – The Difficult 2nd Album…

Note, the UNAS Pro 2 is NOW LIVE on the UniFi Store . The UNAS 4, UNAS Pro 4 and UNAS Pro 8 are now in the site, but are not available till October.

The UniFi UNAS Pro 8 is the latest rackmount NAS in Ubiquiti’s gradually expanding storage lineup and serves as a direct successor to the UNAS Pro released in late 2024. That earlier seven-bay system introduced UniFi’s first attempt at a prosumer-class NAS with 10GbE connectivity and integration into the UniFi ecosystem, but it was limited in scope by its unusual drive count, absence of fan control, and lack of redundant power options. The Pro 8 addresses many of those concerns by standardising the layout to a full eight 3.5-inch bays, adding dedicated M.2 NVMe slots, and adopting a 2U rackmount form factor with hot-swappable dual power supplies. It also includes a set of rails in the box, something not always seen in turnkey solutions of this scale.

From a technical perspective, the UNAS Pro 8 remains anchored to an ARM-based architecture, employing a quad-core Cortex-A57 processor at 1.7 GHz paired with 16 GB of non-upgradeable memory. This positions it differently from x86 alternatives from Synology or QNAP, limiting its scope for high-end virtualisation or transcoding tasks but keeping overall efficiency high. Network expansion is one of its more striking features, with three 10GbE connections — two SFP+ and one copper port — included by default, offering redundancy and multi-channel potential well beyond the capacity of eight SATA drives. Taken together with the dedicated M.2 NVMe caching support and optional redundant PSUs, the Pro 8 represents an incremental but deliberate step forward in UniFi’s second phase of NAS development.

UniFi UNAS Pro 8 Review – Quick Conclusion

The UniFi UNAS Pro 8 is a clear refinement over the first-generation UNAS Pro, standardising the design to eight bays, introducing hot-swappable dual PSU support, and improving cooling and fan control, while also including rack rails for easier deployment. It delivers solid storage functionality with RAID up to level 6, clustered pools, snapshots, encryption, and read/write caching via NVMe modules, though the caching remains limited to automated policies and the required trays are sold separately. Networking is unusually strong for an eight-bay ARM system, with three 10GbE interfaces providing flexibility for aggregation or failover, even if the storage media is unlikely to saturate that bandwidth. Performance testing showed read speeds close to 850 MB/s in RAID 5 with HDDs, with lower write speeds reflecting the ARM Cortex-A57 processor’s constraints, and SSD arrays would likely achieve closer to 10GbE saturation. The operating system has matured but remains more streamlined than established platforms, with no iSCSI, limited protocol support, and basic backup tools, making it more suitable for straightforward file storage than advanced workloads. Ultimately, the Pro 8 fits best for users already invested in UniFi infrastructure or those seeking a rackmount NAS with strong connectivity and efficiency, but it is not yet a direct alternative to feature-rich solutions from long-standing NAS vendors. That said, if you want an incredible value and solid ‘storage-focused’ rackmount NAS solution – this might well be one of the best examples in 2025!

UniFi UNAS Pro 8 Review – Design & Storage

The UNAS Pro 8 adopts a 2U rackmount form factor, measuring 442.4 x 480 x 87.4 mm and weighing 11.5 kg. The enclosure is constructed from SGCC steel, giving it a sturdy industrial build aimed at rack deployments rather than desktop placement. The system ships with rack rails included, which is uncommon among turnkey NAS appliances in this class, reducing the need for additional accessories when integrating it into an existing rack setup. The front panel presents a uniform layout of eight drive bays, standardising the design over the previous model’s unconventional seven-bay configuration and providing a more predictable arrangement for enterprise or prosumer storage planning.

Each of the eight bays supports both 3.5-inch and 2.5-inch HDDs or SSDs, with tool-less trays supplied for ease of installation. Drives slot in securely with a lockable motion, though there is no key-based locking mechanism on the trays themselves, limiting physical access protection. Installation is simple, with trays accommodating both large-capacity HDDs and smaller SSDs through included screws for 2.5-inch drives. While the bays can be partially populated for smaller-scale deployments, the absence of an expansion chassis option means users must fully plan around the eight-bay limit from the outset.

Cooling has been reworked compared with the earlier UNAS Pro. The system now features multiple fans with improved airflow across the drive bays and system board, supplemented by passive ventilation at the front and central areas of the chassis. Fan control has been integrated into the management software, allowing administrators to adjust fan speeds dynamically, a feature missing from the 2024 model. This provides more direct management of system acoustics and thermal balance, which is important given that high-density SATA arrays can run warm under sustained load.

In addition to the primary SATA storage, the rear of the chassis houses two M.2 NVMe slots. These are integrated into removable tray modules with thermal pads and heatsinks designed to dissipate heat from 2280 or 22110 length SSDs. However, the trays are not included by default, requiring a separate purchase if users wish to install their own NVMe drives.

The implementation is mechanically well thought out, but functionally limited: the NVMe drives can currently only be used for read and write caching.

They cannot be assigned to storage pools or volumes, restricting their utility for users seeking to leverage them as a high-speed tier alongside the eight SATA bays.

From a capacity perspective, the eight 3.5-inch bays allow the use of large modern drives, with confirmed compatibility during testing with 30 TB Seagate IronWolf units as well as UniFi-branded re-labelled Western Digital drives. The total maximum capacity therefore depends on the drives chosen, but the system power budget allocates up to 175W for drives, sufficient to support a full complement of high-capacity HDDs.

In practice, UniFi recommends their own labelled drives but does not enforce vendor lock-in, leaving flexibility for users to select from available NAS-grade HDDs and SSDs on the market. This more open stance is in contrast to the drive validation policies adopted by some established NAS vendors, and it provides an important degree of freedom in deployment.

UniFi UNAS Pro 8 Review – Internal Hardware

At the core of the UNAS Pro 8 is an ARM-based processor, specifically a quad-core Cortex-A57 running at 1.7 GHz. This architecture is consistent with UniFi’s approach in the earlier UNAS Pro, prioritising efficiency and lower power draw over raw computational performance. The choice of an ARM SoC means the device is well-suited for file storage, backups, and network-attached services, but it does not provide the same level of support for virtualisation, multimedia transcoding, or container workloads that x86-based systems can deliver. For users considering this system, the hardware direction underlines its positioning as a straightforward storage platform rather than an all-purpose server.

Memory is supplied in the form of 16 GB of LPDDR4, which is soldered to the board and cannot be upgraded. This is a relatively high baseline for an ARM-powered NAS, offering enough headroom for multi-user file access, caching operations, and handling larger RAID arrays without memory saturation. The allocation proved sufficient during array synchronisation tests, though high memory utilisation was observed when building an eight-drive RAID. This suggests the hardware has been provisioned carefully to meet expected workloads, albeit without scope for user expansion if requirements increase later.

The operating system is stored internally on dedicated flash storage, reported within the software as 25.2 GB, likely provisioned as a 32 GB module with some over-provisioning. This design ensures that installed drives remain fully dedicated to storage and that the system can boot independently of the data array. Storage management supports multiple RAID levels up to RAID 6, as well as clustered RAID groupings, providing some flexibility for mixed drive sizes. Combined with hot-swap support and optional failover protection through dual PSUs, the hardware configuration strikes a balance between basic efficiency and the inclusion of some enterprise features.

UniFi UNAS Pro 8 Review – Connectivity & Throughput

The UNAS Pro 8 is equipped with three 10-gigabit network interfaces, consisting of two SFP+ 10G ports and one RJ45 10GbE port with multi-gigabit fallback to 5G, 2.5G, 1G, and 100 MbE. This level of connectivity is notable for a system limited to eight SATA bays, as even high-performance HDDs or SSDs in aggregate are unlikely to saturate more than a single 10GbE link under typical workloads.

While the inclusion of three ports may appear excessive, the arrangement allows for link aggregation, redundancy, and separation of traffic across multiple networks. In practice, this provides administrators flexibility in how the NAS integrates with existing switching hardware, though the real-world performance ceiling remains constrained by the storage media.

Power connectivity is handled through two hot-swappable AC/DC 550W power modules, though only one is included in the base configuration. Installing a second unit enables redundancy, ensuring uninterrupted operation in the event of PSU failure. Testing confirmed seamless failover when one module was removed during sustained read/write operations, with no observable disruption in data availability. However, the absence of USB or UPS integration ports limits external redundancy options, leaving users reliant solely on the dual-PSU configuration for power protection.

In terms of general I/O, the device is closed in design, with no USB ports, HDMI output, or PCIe expansion available. This reflects UniFi’s approach of positioning the system as a dedicated, self-contained appliance managed exclusively via network interfaces and the UniFi OS console. While this reduces versatility for use cases such as direct-attached backups or third-party hardware upgrades, it aligns with the brand’s ecosystem-driven philosophy.

Performance testing with eight 8TB drives in a RAID 5 configuration produced throughput in the region of 800–850 MB/s during sequential read operations. Write speeds were lower, reflecting both the RAID type and the limitations of the ARM Cortex-A57 processor, but still sufficient for multi-user file access and standard NAS workloads. Tests with larger 30TB Seagate IronWolf drives confirmed compatibility, though extended stress testing was not undertaken. With SATA SSDs or a RAID 0 array, the system would likely be capable of saturating a single 10GbE connection, though fully exploiting the three available ports remains unrealistic under the current hardware constraints.

The inclusion of two M.2 NVMe slots, limited to use as read/write cache, provides some performance enhancement. Caching can accelerate frequently accessed data reads or speed up ingest of new data before it is written to the HDD array. However, the caching mechanism is automated, with no user control over cache policies, and the NVMe drives cannot currently be used for storage pools. During operation, thermal imaging recorded SSD module temperatures in excess of 50°C, indicating adequate but stressed cooling under load. This reinforces the importance of active fan management, now included in UniFi’s updated software.

• Networking: 2 x 10G SFP+, 1 x 10GbE RJ45 (5G/2.5G/1G/100M supported)

• Power Supply: 2 x 550W hot-swappable AC/DC modules (1 included)

• Management: Ethernet and Bluetooth 4.1 setup/admin

• Other I/O: None (no USB, HDMI, or PCIe expansion)

• Drive Support: 8 x 2.5″/3.5″ SATA HDD/SSD, 2 x M.2 NVMe (cache only)

• Tested Performance: ~800–850 MB/s sequential reads (RAID 5, HDDs)

• Write Performance: Lower than reads, limited by ARM CPU overhead

• Cache Functionality: NVMe SSDs limited to automated read/write caching

UniFi UNAS Pro 8 Review – Software and Services

The UNAS Pro 8 runs on UniFi’s NAS management platform, designed to integrate with the broader UniFi ecosystem while remaining usable as a standalone system. Administration can be carried out through the UniFi OS console in a web browser or via the ui.com cloud portal, with optional remote access that can be enabled or disabled depending on security requirements.

The platform aims to provide a single interface for storage management, user access, and system monitoring. It is less feature-rich than mature alternatives such as Synology DSM or QNAP QTS, but it retains a streamlined design that prioritises ease of setup and centralised administration.

Storage management supports common RAID levels up to RAID 6, with the additional ability to cluster groups of drives into combined pools. Snapshots are available at the folder level, allowing users to roll back to earlier revisions of files. Encryption is supported, requiring a password to mount encrypted volumes after reboot, which ensures data protection in the event of device theft or unauthorised access.

NVMe SSDs can be assigned to caching, though as noted earlier, they cannot be added to storage pools. File access is available through SMB and NFS, but the range of supported protocols is narrower than on established NAS operating systems.

Backup functionality is split into two categories: system configuration backups and file-level backups. System configuration backups can be stored locally or uploaded to a ui.com account, allowing settings and structures to be restored to the same or another UniFi NAS device.

File-level backups extend to cloud services and other NAS units, with support for scheduled routines and basic rules such as overwrite or versioned backups. Cloud integration is functional but limited compared to established platforms, and external synchronisation features such as continuous sync or third-party plug-ins are not yet available.

User management is relatively straightforward, with the option to bind accounts to the wider UniFi ecosystem or create standalone local users. Access can be restricted to LAN-only connections, while two-factor authentication is available through UniFi’s identity and verification tools. At present, some advanced functions common to other platforms, such as iSCSI target creation or scheduled power management, remain absent.

The software continues to evolve, with updates adding features incrementally, but its current focus is on providing reliable core storage, backup, and access management rather than competing directly with the broad feature sets of long-established NAS vendors.

UniFi UNAS Pro 8 Review – Verdict and Conclusion

The UniFi UNAS Pro 8 represents a measured but important step forward compared with the earlier UNAS Pro model released in 2024. By moving to a uniform eight-bay arrangement, it avoids the odd seven-bay design that limited the practicality of the previous system and brings it in line with industry expectations for rackmount storage. The addition of dual hot-swappable power supply modules, though only one is supplied by default, introduces a level of redundancy that was absent in the earlier generation and proved reliable during testing with seamless failover. Improvements to cooling and fan control further distinguish it, with administrators now able to actively manage system noise and temperature rather than relying on fixed presets. UniFi has also bundled rack rails and a robust accessory kit, which simplifies installation and deployment. At the same time, the reliance on an ARM Cortex-A57 processor keeps the platform efficient but restricts its performance ceiling, limiting its suitability for high-throughput tasks such as large-scale virtualisation, multimedia transcoding, or environments where sustained multi-gigabyte per second throughput is essential.

On the software side, UniFi’s NAS operating system has matured since the first-generation release but still prioritises simplicity over feature breadth. The UNAS Pro 8 includes key storage capabilities such as RAID up to level 6, clustered pools, snapshots, encryption, and read/write caching via the rear-mounted NVMe modules. However, those same M.2 slots remain limited to caching only, and the trays required for installation must be purchased separately, which may be seen as an unnecessary barrier. Network protocol support is limited to common services such as SMB and NFS, with no iSCSI implementation, reducing its appeal for professional editing environments or enterprise applications that depend on block-level storage. Cloud and LAN backups are supported with basic scheduling and rules, but the absence of broader synchronisation features or third-party integration keeps it behind more mature platforms. The Pro 8 therefore delivers dependable core NAS functions but does not yet challenge the established ecosystems of Synology or QNAP. For organisations already invested in UniFi’s infrastructure or those requiring a straightforward rackmount storage system with multiple 10GbE connections, it offers a compelling option, but it remains best suited to use cases focused on file storage and backup rather than advanced workloads.

Kind of insane actually, for a 8x SATA drive machine Dual PSU and Failover hugely welcome, after it’s omission on the UNAS Pro 2024 16GB RAM out the box is a significant upgrade over the UNAS Pro from 2024 Benefits from almost a year of development of the UNAS Pro by UniFi, resulting in a much more complete solution in both hardware and software Rackmount rails are included in the UNAS Pro 8 retail box, and are of a high quality Exceptionally appealing price point Supports complete network/local access if preferred, as well as full remote connectivity with the UI.com account and site manager services Wide Hard Drives and SATA SSD Support (UniFi branded drives and those from 3rd parties such as Seagate Ironwolf, WD Red and Toshiba N300) Ditto for the m.2 NVMe support, though you will need to m.2 adapter trays Comprehensive network storage software in UniFi NAS OS and Drive. Latest OS updates have included fan control, flexible RAID configurations, encrypted drive creation, customizable snapshots, more backup client choices/targets ‘Single Pane of Glass’ management and monitoring screen is very well presented! One of the fastest to deploy turnkey NAS solutions I have ever personally used!

Lack of USB connectivity for convenient plug and share storage drives, network upgrades, 3rd party UPS support and more Very modest base hardware, but understandable relative to the price HDD injection is very unique, but prevents hot swapping Still a lack of client applications native to the NAS services for Windows, Mac, Andoid and Linux Shame about the LCD/LCM control panel being absent M.2 NVMes are not usable for storage pools, just read/write caching – which is a shame, given the large network connectivity available here

The UniFi UNAS 2 NAS Review – Value vs Scale

Note, the UNAS Pro 2 is NOW LIVE on the UniFi Store . The UNAS 4, UNAS Pro 4 and UNAS Pro 8 are now in the site, but are not available till October / Q4 2025

The UniFi UNAS 2 is a compact, entry-level two-bay desktop NAS introduced as part of Ubiquiti’s second phase of NAS development, following the debut of the UNAS Pro in 2024. That earlier seven-bay rackmount system was notable for its low $499 price and integrated 10GbE connectivity, but it had an unconventional design, limited fan control, and no support for USB expansion. By contrast, the UNAS 2 shifts away from rackmount hardware and into the desktop market, adopting a much smaller form factor and prioritising simplicity over raw performance. Measuring 13.5 x 12.9 x 22.37 cm and weighing only 1.3 kg, it is one of the smallest systems in the UniFi NAS range and is constructed from polycarbonate rather than steel, reinforcing its role as an affordable, lightweight device.

The hardware is designed primarily for modest storage requirements, supporting two 3.5-inch hard drives with a maximum combined power budget of 52W and an overall consumption ceiling of 60W. The device operates on a single 2.5 GbE RJ45 interface, which also functions as a PoE++ input, removing the need for a conventional power supply unit but requiring either a compatible PoE++ switch or the included 60W injector. This approach marks a clear departure from the UNAS Pro, which included a standard power connector and optional redundancy through additional PSU modules. In practice, the reliance on a single port for both power and data streamlines installation within UniFi networks, but it also introduces a single point of failure and reduces flexibility compared with larger systems.

UniFi UNAS 2 Review – Quick Conclusion

The UniFi UNAS 2 is a compact, entry-level NAS that prioritises simplicity and integration within the UniFi ecosystem over flexibility or raw performance. Its use of PoE++ for both power and connectivity makes installation straightforward in environments with compatible UniFi switches, but it introduces reliance on a single port and limits deployment outside that infrastructure, even with the included injector in the retail kit. The system supports two 3.5-inch drives in a shared non–hot-swappable tray, with RAID 1, or single-disk setups available, but there is no option for expansion or NVMe caching. Hardware consists of a quad-core ARM Cortex-A55 processor with fixed 4 GB of LPDDR4 memory, which is efficient but imposes clear limits on throughput and application scope. Performance testing produced read speeds up to 260 MB/s and writes in the 160–180 MB/s range, sufficient for the 2.5 GbE interface but reflective of the modest hardware and thermal constraints, with CPU temperatures often approaching 80°C under load. Software provides a clean interface with snapshots, RAID tools, backups to other UniFi NAS or cloud services, and user management tied to UniFi identity, but features such as iSCSI, encryption, and granular backup rules are absent. As a result, the UNAS 2 is best suited as a secondary or edge storage device, particularly for UniFi users seeking easy integration, but it lacks the scalability and depth of established NAS platforms needed for primary or enterprise deployments.

UniFi UNAS 2 Review – Design

The UNAS 2 adopts a small desktop form factor, measuring 135 x 129 x 223.7 mm and weighing 1.3 kg. Its enclosure is constructed from polycarbonate, which makes it lighter and less industrial than the steel-based rackmount models in UniFi’s NAS range. The compact build is suited for environments where space is limited, and it operates within an ambient temperature range of -5 to 40°C and a humidity tolerance of 10–90% non-condensing. With only two drive bays, the UNAS 2 positions itself as an edge device for simple storage and backup, rather than a primary data management system.

Drive installation is handled through a single removable cage that holds both 3.5-inch drives. Each drive clips into place using a shared tray design, with both units inserted in opposite orientations to align with the SATA connectors. While this arrangement is functional, it has some limitations.

There is no support for hot swapping, meaning the system must be powered down before drives can be replaced. Additionally, the shared cage design requires both drives to be handled together, which increases the risk of disturbing a healthy drive when removing or replacing a failed one.

Cooling is managed by a small fan located at the rear, supported by passive ventilation channels at the base of the unit. Air is drawn in from underneath and expelled from the top section, ensuring airflow across the drives and the system board. Thermal tests recorded CPU temperatures in the range of 75–80°C during higher utilisation, with the chassis surface reaching around 39–50°C depending on workload.

The fan is adjustable via UniFi’s management interface, offering a choice between balanced operation and higher cooling at the expense of noise.

Noise levels ranged from 31–32 dBA in idle to 35–38 dBA under load, influenced heavily by the vibration of installed drives.

At the front of the unit, UniFi has integrated a 1.47-inch colour LCM display for system information. This provides basic details such as network status, storage health, and system alerts, but it is not touchscreen and cannot be used for configuration.

The lack of interactive control means that most management tasks still need to be handled through the UniFi OS console. LED indicators are also present for system status, and a physical locking mechanism is built into the drive cage, preventing accidental removal.

From a storage perspective, the UNAS 2 supports a simple RAID configuration for two drives, namely RAID 1, in addition to single-disk setup. Given the limitations of two-bay devices, RAID 1 is the most practical option, prioritising data protection over capacity.

The system officially supports large-capacity HDDs, with tests confirming compatibility up to 30 TB drives. However, there is no expansion capability through additional enclosures, and the single USB-C port on the front is limited to attaching external drives for storage or backups. This means users are confined to the internal two-bay maximum, making long-term planning important for deployment.

UniFi UNAS 2 Review – Internal Hardware

The UNAS 2 is built around a quad-core ARM Cortex-A55 processor clocked at 1.7 GHz. This CPU architecture is designed for efficiency rather than high computational output, which makes it suitable for low-power storage operations, but less capable for advanced workloads such as virtualisation, heavy encryption, or on-the-fly media transcoding.

During testing, CPU temperatures generally remained in the 75–80°C range under sustained use, dropping closer to 50–60°C when idle or under light activity. While these figures fall within operating limits, they reflect the modest cooling design of the enclosure and the limited thermal headroom of the ARM-based hardware.

The device includes 4 GB of LPDDR4 memory, which is soldered to the board and cannot be expanded. This fixed allocation is sufficient for handling RAID 1 synchronisation, snapshots, and standard multi-user file operations, but it sets a ceiling on the system’s multitasking capability.

Unlike larger UniFi NAS models that feature 16 GB of memory, the UNAS 2’s hardware is intended only for light to moderate workloads. Memory use during testing reached high utilisation during RAID synchronisation but did not exceed available capacity, suggesting that UniFi has provisioned enough for the intended use case, while keeping the system constrained to its role as an entry-level solution.

The operating system is stored internally and runs independently of the installed drives, leaving both bays available for data. This separation ensures that the system can still boot even if both drives are removed or replaced. Storage management is limited to the basic RAID levels supported by two-bay systems, and no M.2 NVMe slots are included for caching or tiered storage, a feature reserved for larger UniFi NAS models. As such, the internal hardware of the UNAS 2 reflects its role as a secondary or edge device, designed primarily for straightforward storage and backup within a UniFi-managed network.

UniFi UNAS 2 Review – Connectivity & Performance

The UNAS 2 relies on a single 2.5 GbE RJ45 port for both data and power, with PoE++ providing up to 60W of combined budget. This integration reduces cabling and eliminates the need for an external power brick, but it introduces a single point of failure. That said, the UNAS 2 retail kit DOES include a PoE mains adapter, so ultimately the end user does have the option of deploying in a traditional manner (though power and network connectivity are still funnelled into the same connector).

If the cable or port fails, both power and connectivity are lost. A 60W PoE++ injector is included in the package for users without a compatible PoE++ switch, but this approach remains less flexible than traditional dual-port NAS designs. There is no secondary network interface, Wi-Fi connectivity (rare in a system of this scale, but would allow for failover if it was), support of a USB network adapter or option for link aggregation, which makes the system dependent on one connection for all network and power needs.

In addition to the Ethernet port, the front of the device includes a USB-C interface rated at 5 Gbps. This provides the ability to attach external storage devices, enabling data import, backups, or temporary storage expansion. However, the USB port is limited to storage and does not support network adapters, UPS integration, or official expansion enclosures. While the addition of USB-C addresses one omission from the UNAS Pro, its functionality is constrained and focused solely on external drive access.

Network throughput reflects the limitations of a dual-drive ARM-based NAS. In testing with two 8TB HDDs in RAID 1, sequential read speeds reached around 260 MB/s, while write speeds varied between 160–180 MB/s depending on workload. Benchmarks such as AJA and CrystalDiskMark confirmed this pattern, with read performance consistently higher than write due to the processor’s handling of RAID and data caching. These figures make effective use of the 2.5 GbE interface but leave no capacity to challenge higher multi-gigabit standards.

Power consumption aligns with UniFi’s published specifications, averaging 16–17W in idle, 18–20W during light activity, and 23–24W under heavier use. Peak usage during sustained transfers with RAID synchronisation reached approximately 25W, well below the 60W ceiling. Thermal monitoring showed the CPU rising toward 79–80°C under stress, though the chassis fan helped bring temperatures back into the 50–60°C range once load reduced. These results indicate that while the system operates within its defined limits, sustained workloads push the ARM processor and cooling system close to their maximum operating range.

Noise levels were modest, with idle operation producing around 31–32 dBA and workloads raising this to 35–38 dBA. The shared dual-drive cage design contributed to additional vibration, particularly when placed on a hard surface. Rubberised feet help dampen this effect, but vibration noise was noticeably reduced when the device was placed on softer material such as foam. Overall, while the system remains relatively quiet, its acoustic profile is closely tied to the drives selected and the surface it rests on.

• Network Interface: 1 x 2.5 GbE RJ45 (PoE++)

• USB Ports: 1 x USB-C (5 Gbps, storage only)

• PoE Power Budget: 60W (52W available for drives)

• Power Supply: 60W PoE++ injector included

• Max Consumption: 60W (typical 16–25W during use)

• Tested Performance: ~260 MB/s reads, 160–180 MB/s writes (RAID 1, HDDs)

• Noise Levels: 31–32 dBA idle, up to 38 dBA under load

• Temperature Range (Observed): 75–80°C CPU under stress, 50–60°C idle/light use

UniFi UNAS 2 Review – Software and Services

The UNAS 2 runs on UniFi’s NAS management platform, which follows the same single-pane-of-glass interface design seen in the UNAS Pro and UNAS Pro 8. Administration is carried out via a web browser or through a ui.com account, with the option to disable cloud access and operate the system entirely on a local network.

The interface consolidates system status, storage health, user accounts, and backup management into one dashboard. While straightforward to use, it does not provide the same level of customisation or feature depth offered by longer-established NAS operating systems such as Synology DSM or QNAP QTS.

Storage management is limited by the two-bay architecture. Users can create RAID 1 volumes, or operate drives independently. Drive health monitoring, temperature reporting, and snapshot scheduling are all included, allowing basic resilience and file recovery options.

Snapshots can be created and managed at the folder level, with the ability to lock snapshots to prevent deletion. Encryption, however, does not appear to be available on the UNAS 2, in contrast to larger UniFi NAS models where encrypted volumes are supported.

Backup functionality includes both system configuration and file-level options. Configuration backups can be stored locally or uploaded to a ui.com account, allowing the system to be restored quickly if reset or replaced. File-level backups extend to other UniFi NAS systems and selected cloud services, including Google Drive, with scheduling available for automation.

Local LAN backups to other storage devices via SMB are also supported, though filtering and exclusion rules are limited. The system is therefore capable of basic backup routines but lacks the more granular tools available on competing platforms.

User and access management is integrated into the UniFi ecosystem. Administrators can create local accounts or bind accounts to UniFi’s identity services, with two-factor authentication supported via the UniFi Verify app.

Permissions can be set at the folder level, and users can be restricted to LAN-only access if required. Supported protocols include SMB and NFS, but there is no iSCSI target functionality, limiting its application in virtualisation or editing workflows.

The software also includes fan control and system monitoring tools, but resource reporting is basic, with only CPU and memory utilisation graphs available.

Overall, the software reflects UniFi’s effort to balance simplicity with integration, but it remains less comprehensive than that of established NAS vendors.

UniFi UNAS 2 Review – Verdict and Conclusion

The UniFi UNAS 2 is presented as a compact and affordable two-bay NAS designed for straightforward storage and backup tasks, particularly within environments already using UniFi networking hardware. Its PoE++ design is distinctive, allowing both power and connectivity to be delivered over a single cable, simplifying installation where compatible PoE switches are available. This approach aligns with UniFi’s strategy of reducing external hardware requirements, though it also means that a failed port or damaged cable will disable both power and network access simultaneously. For non-UniFi users, the reliance on PoE++ creates an additional barrier, as adoption requires either compatible infrastructure or the included 60W injector. The shared dual-drive tray, lack of hot-swap support, and absence of expansion options further reinforce the system’s role as a fixed-capacity solution, best suited to smaller or secondary deployments. With a maximum drive budget of 52W and overall consumption limited to 60W, the device is power-efficient, but its architecture prioritises simplicity over flexibility.

On the software side, the UNAS 2 provides a user-friendly interface with access to snapshots, RAID configuration, system backups, and integration into the UniFi identity ecosystem. However, the limited hardware constrains the range of features available, and certain tools seen in UniFi’s larger NAS models are absent, such as encrypted volumes or extended network protocol support. Performance testing showed sequential read speeds up to 260 MB/s and write speeds around 160–180 MB/s, which make full use of the 2.5 GbE interface but leave little headroom for more demanding tasks. Thermals during extended use regularly pushed the CPU into the high 70s Celsius, and although fan management can be adjusted, sustained workloads highlight the limits of the system’s cooling design. The software’s omission of iSCSI and advanced backup filters also narrows its role, making it less competitive against established vendors in professional or virtualisation scenarios.

Ultimately, the UNAS 2 is most appropriately positioned as an edge or secondary NAS, providing basic networked storage for existing UniFi users who value plug-and-play deployment and ecosystem consistency, but it is not equipped to serve as a primary system in larger or more demanding environments (VMs, Containers, etc). A great and unique NAS that will nbe at it’s most appealing if you are already invested in the UniFi ecosystem, or have a NAS already that needs a network backup.

Why are NAS Systems not 10GbE as Standard Right Now?

It is 2025, yet the majority of NAS systems on the market continue to ship with 1GbE or, at best, 2.5GbE networking, leaving many users questioning why 10GbE has not become a standard feature. Over the past decade, the cost of 10GbE networking equipment, including switches, NICs, and adapters, has steadily declined, and the technology has long since moved from being an enterprise-only option into mainstream availability. Home labs, creative professionals, and small businesses are increasingly working with 4K and 8K media, large VM environments, and multi-terabyte datasets, all of which can easily saturate a 1GbE or even 2.5GbE connection. Despite this shift, when browsing the portfolios of Synology, QNAP, Asustor, TerraMaster, or even newer DIY-friendly NAS brands, the entry-level and mid-tier systems remain locked at bandwidth speeds that are already dwarfed by modern SSD arrays and multi-bay RAID configurations.

asdasd

This gap between user expectations and manufacturer offerings has become more striking as affordable consumer motherboards and even some mini-PCs now integrate 5GbE or 10GbE as standard. By contrast, NAS vendors still tend to position 10GbE as a high-end add-on or restrict it to flagship models, often requiring costly proprietary NIC upgrades. For the average buyer, this creates the perception that NAS devices are lagging behind broader networking trends and are artificially constrained to maintain price tiers. The reality is more complex. The question of why 10GbE has not become universal in NAS hardware cannot be answered solely by pointing to falling market prices of controllers and switches. Instead, the explanation lies in a mix of economics, hardware design limitations, CPU lane allocations, and the fact that networking itself is evolving beyond 10GbE into alternatives like 25GbE and USB4. All of these factors together show why the integration of 10GbE into NAS devices remains more complicated than it may first appear.

Discussing the Issue / Barriers to Manufacturers

One of the most persistent barriers to universal 10GbE adoption in NAS systems is the economic reality of how these devices are positioned. Vendors like Synology, QNAP, and Asustor operate in a layered product ecosystem, where each tier is designed to push customers toward more expensive models. Entry-level devices often compete on affordability rather than raw performance, meaning that features like 10GbE are deliberately held back to differentiate mid-range and enterprise systems. The actual bill of materials (BOM) cost for including 10GbE hardware is lower than it was five years ago, but manufacturers still view it as a premium feature that justifies higher price points. By holding 10GbE in reserve for upper tiers, vendors protect their margins, avoid cannibalising sales of more profitable models, and keep upgrade paths clear for customers as their needs grow. This is not simply technical gatekeeping but a conscious market segmentation strategy.

A second, more technical challenge comes from CPU and chipset design. The processors used in affordable NAS devices are almost always low-power embedded models—Intel Celeron, Atom, or entry-level AMD Ryzen Embedded chips—which provide only a limited number of PCIe lanes. These lanes must be distributed across storage controllers, NVMe slots, expansion slots, and network interfaces. Introducing 10GbE requires not only dedicating at least two, and often four, PCIe lanes, but also ensuring that the CPU can handle the higher throughput without becoming the bottleneck. If a vendor reallocates lanes to add 10GbE, they may have to reduce the number of NVMe slots, cut down on SATA ports, or compromise expansion card bandwidth. For many manufacturers, it is simpler to leave 10GbE out of the base design than to risk producing a system that looks good on paper but struggles to deliver in practice.

Beyond lane allocation, there is also the issue of power, thermals, and board layout. 10GbE controllers typically draw more power and generate more heat than 1GbE or 2.5GbE chips. In compact NAS enclosures designed for low-noise operation, this can force more aggressive cooling solutions or tighter thermal management. For brands already working within strict acoustic and energy efficiency limits, especially in home or small office NAS devices, the integration of 10GbE becomes a balancing act between speed and stability. Higher thermal load can also reduce the overall lifespan of components or require larger enclosures, both of which erode the appeal of entry-level systems where buyers expect compact and efficient designs.

Another factor that discourages widespread 10GbE adoption is ecosystem alignment. NAS vendors are keenly aware that a large percentage of their target audience does not yet operate in 10GbE-ready environments. Even though 10GbE switches and NICs are more affordable in 2025, many households and small offices still rely on routers and switches with 1GbE or 2.5GbE uplinks. For these users, the inclusion of 10GbE would have little practical benefit, since the rest of the network infrastructure cannot support it. From the manufacturer’s perspective, bundling 10GbE into a device that will simply be throttled by the customer’s network backbone risks making the feature look pointless, or worse, “non-functional.” As such, 10GbE tends to be reserved for prosumer and enterprise segments, where it is more likely that users already have or are willing to invest in compatible infrastructure.

Finally, there is a subtle but important business factor at play: vendor ecosystems and upsell opportunities. Many NAS brands sell proprietary 10GbE upgrade cards or branded NICs, which can only be used with their systems. By omitting onboard 10GbE but providing expansion slots, vendors create an additional revenue stream while giving customers flexibility to upgrade later. This model also ensures that users who truly require 10GbE end up spending more within the brand’s ecosystem, while casual buyers stick to lower-cost systems that do not overdeliver. In this sense, the absence of 10GbE on affordable NAS units is not only about technical limitations, but also about preserving a staged upgrade model that aligns with each brand’s long-term revenue strategy.

The Solution – How Can 10GbE Be More Accessible?

The landscape for 10GbE networking hardware has improved significantly in the last few years, with controllers becoming cheaper, more efficient, and easier to integrate into consumer systems. Early 10GbE relied heavily on costly Intel or Mellanox chipsets designed primarily for enterprise servers, often priced in the hundreds of dollars per card. Today, vendors such as Realtek, Aquantia (now under Marvell), and Broadcom produce consumer-focused 10GbE controllers that are smaller, run cooler, and consume less power. These newer chipsets are also designed to integrate more smoothly with mainstream CPUs and motherboards, reducing the need for complex PCB layouts. The result has been a marked reduction in the cost of standalone NICs and USB-to-10GbE adapters, which now frequently sell for under $100, making them accessible even for home users experimenting with faster networking.

Even with this progress, manufacturers remain hesitant to make 10GbE a baseline feature across all NAS devices. Part of the reason lies in how modern NAS systems must juggle limited resources. As CPUs have shifted to PCIe Gen 4 and Gen 5, the available bandwidth has increased, but vendors are also using these lanes to expand NVMe storage pools, enable GPU acceleration, or add AI-focused co-processors for surveillance, indexing, or media analysis. In many cases, vendors see greater value in offering more M.2 slots, dual PCIe expansion options, or flexible NIC bays than in permanently dedicating space to 10GbE. This explains why hybrid designs are now common: devices shipping with 2.5GbE or 5GbE onboard, with a dedicated slot for an optional 10GbE card. Such configurations give users a faster-than-gigabit baseline, but also keep upgrade paths open for power users who truly need multi-gigabit networking.

The state of 10GbE is also being influenced by the rapid adoption of adjacent technologies. 2.5GbE has become the de facto standard in new consumer motherboards and mid-tier switches, offering a cheap and widely compatible upgrade path for everyday users who want more than 1GbE without changing their cabling. At the other end of the spectrum, higher-speed networking such as 25GbE or 40GbE is filtering down from data centres to advanced prosumer setups, while direct-connect solutions like Thunderbolt 4 and USB4 offer bandwidth well beyond 10GbE with less CPU overhead and simpler plug-and-play deployment. Software optimisation is also playing a role: modern NAS operating systems increasingly support IP over Thunderbolt or USB4, which provides a parallel path to multi-gigabit performance without the traditional reliance on Ethernet standards. As a result, 10GbE finds itself squeezed in the middle—too expensive to be a no-brainer at the entry level, but increasingly overshadowed by faster alternatives at the top end. It remains a critical sweet spot for small businesses and creative professionals, but its window of dominance is being challenged by the pace of networking innovation.

Verdict and Conclusion – Buy a 10GbE NAS Now or Wait?

The question of why 10GbE has not become a standard feature across NAS devices in 2025 does not have a single answer, but rather a convergence of factors. Manufacturers face technical challenges in CPU lane allocation, thermal management, and system design, while also making deliberate market choices to protect product segmentation and encourage upsell opportunities. At the same time, 10GbE sits in an awkward position within the networking landscape: cheaper and more efficient than ever, yet increasingly bypassed by the widespread adoption of 2.5GbE on the low end and the emergence of 25GbE, Thunderbolt, and USB4 on the high end. For now, this means that 10GbE remains reserved for higher-tier NAS systems where the hardware can genuinely sustain its throughput and where the user base is prepared to invest in compatible infrastructure. While prices will continue to fall and adoption will grow, it is unlikely that every NAS will adopt 10GbE as standard before other technologies begin to replace it as the next performance baseline.

5 affordable Turnkey 10GbE NAS Solutions (Between $499 and $699)

For years, 10GbE networking has been seen as a premium feature reserved for high-end or enterprise-grade NAS devices, often pushing total system costs well beyond the reach of home users and small businesses. However, as controller prices have dropped and demand for faster data transfers has grown, a new wave of affordable NAS solutions has started to appear with built-in 10GbE. These systems no longer require expensive proprietary upgrade cards or third-party NICs, and many sit comfortably below the $699 / £599 price point. They cover a range of use cases, from compact SSD-based NAS devices to rackmount storage appliances and versatile desktop units. Below is a selection of some of the most notable options currently available, each offering a balance of performance, connectivity, and affordability for users who want to move beyond 1GbE or 2.5GbE without breaking the bank.

UniFi UNAS Pro (7-Bay, Rackmount)

I keep coming back to two words for the UniFi UNAS Pro—fundamentals and consistency. UniFi has clearly focused on making this system a strong addition to their ecosystem, prioritizing the essential storage needs of a NAS. They’ve succeeded in this, but comparisons with long-established competitors are inevitable. While solid, reliable, and stable, the UniFi UNAS Pro will take time to be competitive on the software front. If you’re deeply invested in the UniFi ecosystem, you’ll appreciate its ease of use and integration. However, outside of a UniFi network, it may feel feature-light compared to alternatives. The pricing is competitive for a launch product at $499, and while it’s not the best NAS on the market, it’s the most user-friendly and UniFi-ready. It will likely satisfy many users’ needs. I can certainly see this being integrated into existing UniFi networks as a 2nd stage backup alongside their already existing 3rd party NAS solution, with the potential to graduating to their primary storage as Ubiquiti continue to evolve this platform above and beyond the fundamentals their have nailed down in the UNAS Pro system.

• Approx. Price: $499 / £400

• Specs: ARM Cortex-A57 quad-core CPU, 8 GB RAM, seven 2.5″/3.5″ SATA bays, 1×10GbE SFP+ and 1×1GbE.

• Why It Stands Out: Exceptional price-to-performance for pure storage needs. Lacks advanced multimedia or container apps but ideal for high-speed backups in a rackmount setup.

UGREEN NASync DXP4800 Plus

BOTTOM LINE – The UGREEN NASYnc DXP4800 Plus does not feel ‘finished’ yet and still needs more time in the over, but UGREEN have been very clear with me that this product is not intended for release and fulfilment till summer 2024 and improvements, optimization and product completion is still in progress. Judging the UGREEN NAS systems, when what we have is a pre-release and pre-crowdfunding sample, was always going to be tough. The DXP4800 PLUS is a very well put-together NAS solution, arriving with a fantastic launching price point (arguably even at its RRP for the hardware on offer). UGREEN has clearly made efforts here to carve out their own style, adding their own aesthetic to the traditional 4-bay server box design that plagues NAS boxes at this scale. Equally, although they are not the first brand to consider Kickstarter/Crowdfunding for launching a new product in the NAS/personal-cloud sector, this is easily one of the most confident entries I have seen yet. The fact that this system arrives on the market primarily as a crowdfunded solution (though almost certainly, if successful, will roll out at traditional retail) is definitely going to give users some pause for thought. Equally, the UGREEN NAS software, still in beta at the time of writing, although very responsive and nailing down the basics, still feels like it needs more work to compete with the bigger boys at Synology and QNAP. Hardware architecture, scalability, and performance are all pretty impressive, though the performance of the Gen 4×4 M.2 NVMe slots didn’t seem to hit the numbers I was expecting. Perhaps a question of PCIe bottlenecking internally, or a need for further tweaking and optimization as the system continues development. Bottom line, with expected software updates to roll out closer to launch and fulfillment, such as an expanded App center and mobile client, the UGREEN DXP4800 Plus is definitely a device worth keeping an eye on in the growing Turnkey and semi-DIY NAS market. As an alternative to public cloud services, this is a no-brainer and worth the entry price point. As an alternative to established Turnkey NAS Solutions, we will hold off judgment till it is publicly released.

• Approx. Price: $595 / £475

TerraMaster F4-424 Max / F6-424 Max

The TerraMaster F4-424 Max is a robust 4-bay NAS system that offers a powerful mix of features and flexibility for a wide range of tasks. Powered by the Intel i5-1235U CPU with 10 cores and 12 threads, the F4-424 Max excels at resource-intensive applications such as Plex media streaming, 4K hardware transcoding, and virtual machine hosting. Its dual M.2 NVMe slots running at PCIe Gen 4 speeds significantly improve storage performance, especially when used for caching, while the two 10GbE ports offer high-speed networking environments, allowing for 20Gbps throughput via link aggregation.

In terms of software, TOS 6 brings notable improvements, although it still lags behind the more polished ecosystems of Synology DSM and QNAP QTS. That said, TerraMaster’s continuous software evolution with each new version of TOS ensures that users have access to more robust tools and security features. For its price point of $899.99, the F4-424 Max is a compelling option for those seeking high-performance NAS solutions with scalability in mind. While the Pro model offers competitive performance, the Max takes it a step further with advanced networking, making it ideal for environments where speed is a priority.

• Approx. Price: $675 / £550 (F4-424 Max, during sale) – $899 / £700 (F6-424 Max, regular)

• Specs: Intel Core i5-1235U (10-core), 8 GB RAM, dual 10GbE ports, dual M.2, with 4 or 6 SATA bays depending on model.

• Why It Helps: The F4-424 Max frequently drops below the $800 mark in promotions, offering unusually strong CPU performance and dual 10GbE at a mid-range price point.
