The Terramaster F4-425 PLUS NAS Review – Design & Storage

The exterior design of the TerraMaster F4-425 Plus maintains the brand’s familiar compact metal chassis but introduces small refinements that improve both usability and thermals. Measuring 150 by 181 by 219 millimeters and weighing just under 3 kilograms, it fits comfortably into a home office or studio setup without generating significant heat or noise. The enclosure is almost entirely metal, with a brushed silver finish that enhances rigidity and passive cooling compared with earlier plastic-faced designs. Four individual drive trays occupy the front panel, each featuring a simple click-and-load mechanism for 3.5-inch or 2.5-inch drives. Although there are no locking latches or LCD displays, the trays are tool-free and straightforward to handle. A single 120mm fan at the rear provides adjustable cooling across smart, low, and high-speed profiles, maintaining an operational noise level as low as 20.9 dB(A) when idle with drives installed, according to TerraMaster’s own test figures.

From a structural perspective, the F4-425 Plus has clearly benefited from improved thermal management. The metal shell acts as a heat spreader, with typical external temperatures ranging from 25 to 27°C across the enclosure after extended operation, even under multi-day workload testing. Internal drive bays were observed to maintain around 27 to 29°C, while the rear ports and fan area registered between 36 and 38°C during prolonged use. These figures indicate an efficient heat dissipation design, aided by the more conductive chassis material and smart fan calibration. For users concerned with energy efficiency, the power draw remains modest thanks to the Intel N150 processor’s low TDP, allowing the system to idle at roughly 13 watts with SSDs installed and scale to around 60 watts under sustained load with four enterprise-class HDDs spinning.

In terms of drive configuration, the NAS supports up to four SATA 6Gb/s drives and three M.2 2280 NVMe SSDs. This combination provides a theoretical maximum raw capacity of 144TB, assuming four 30TB HDDs and three 8TB SSDs. The inclusion of three NVMe slots rather than the more typical one or two is a notable strength. Each operates on a PCIe 3.0 x1 lane, delivering real-world throughput of approximately 800 to 900 MB/s per SSD, suitable for caching or storage pools. This setup makes it possible to allocate two drives for cache acceleration while dedicating the third to an independent SSD-based pool for high-speed operations like video editing or database hosting. Such flexibility is rare at this price point and broadens the system’s appeal to users with both large data sets and high-performance requirements.

Storage management is handled through TOS 6, TerraMaster’s web-based operating system, which supports a wide range of RAID configurations including TRAID, TRAID+, JBOD, and traditional RAID 0, 1, 5, 6, and 10. TOS 6 also enables SSD caching, snapshots, and HyperLock write-once-read-many functionality for data integrity. Users can assign storage pools to specific workloads, such as separating SSD-based scratch space from HDD archival volumes. Combined with the new graphical interface and more detailed health monitoring tools, it provides a much more transparent overview of drive temperatures, utilization, and S.M.A.R.T. status.

This approach aligns with the unit’s target demographic of small offices, creators, and advanced home users who want server-grade responsiveness without enterprise complexity.

Storage connectivity within the system is distributed between four SATA III 6Gb/s interfaces managed by an ASMedia controller and three PCIe 3.0 x1 lanes dedicated to M.2 NVMe SSDs. This configuration ensures balanced throughput for simultaneous HDD and SSD activity. Internally, the layout is straightforward, providing easy access to both the memory slot and M.2 bays via the removable top panel. The power supply is a single 90W external brick, keeping internal temperatures lower and simplifying maintenance.

Together, the hardware configuration represents a thoughtful balance between efficiency, expandability, and performance, aimed at users who need consistent data access, multimedia capabilities, and reliable long-term operation without excess noise or heat.

The Terramaster F4-425 PLUS NAS Review – Ports and Connections

The TerraMaster F4-425 Plus offers a broad range of connectivity designed to meet both high-speed networking and general expansion needs. On the rear panel, two 5GbE RJ-45 network ports serve as the central performance feature. These are among the first dual 5GbE implementations in a mid-tier NAS, and each port operates through its own dedicated PCIe 3.0 x1 lane, avoiding bandwidth contention. In testing, each port achieved full theoretical throughput, confirming proper lane allocation. Users can enable link aggregation or SMB multichannel for multi-user workloads, although saturating both ports simultaneously requires fast SSD or hybrid storage configurations. These ports support IPv4/IPv6, VLAN tagging, link aggregation, and Wake-on-LAN, making the system suitable for both small office environments and direct workstation connections.

Complementing the network interfaces, the F4-425 Plus includes four USB 3.2 ports: three Type-A and one Type-C, all operating at 10Gbps. These ports can handle external DAS enclosures, UPS devices, or high-capacity backup drives. The inclusion of a front-mounted USB port improves convenience for ad hoc backups or quick file transfers, addressing a long-standing omission in earlier TerraMaster models. Additionally, an HDMI 2.1 output is positioned on the rear, though its practical use remains limited within TOS, which lacks a native display interface. It may, however, prove useful for third-party operating systems such as Unraid or TrueNAS, where direct console access or local media playback is desired.

Overall, the port layout is clean and efficient, optimized for straightforward cable management. The system’s single large fan sits adjacent to the networking array, allowing for effective airflow without excessive cable obstruction. Power is supplied through a standard barrel connector linked to an external 90W adapter, which helps reduce internal heat buildup. Though it lacks built-in 10GbE or PCIe expansion, the dual 5GbE setup provides more than enough bandwidth for its class, especially when paired with NVMe caching. Users can also connect the NAS to TerraMaster’s USB-based DAS units for storage expansion or off-site replication, offering flexibility without compromising portability or noise levels.

The Terramaster F4-425 PLUS NAS Review – Tests, Noise, Heat and Power Consumption

Performance testing on the TerraMaster F4-425 Plus showed that the system comfortably meets its advertised speed class, particularly when networked over a single 5GbE connection. Using four Toshiba MG-series 7200 RPM enterprise hard drives configured in RAID 5, the system achieved full saturation of one 5GbE port during both AJA and ATTO benchmark tests, reaching consistent read and write speeds around 500 to 520 MB/s. When tested with mixed media files totaling 50.5 GB, it completed the transfer in approximately 3 minutes and 45 seconds, equating to an average throughput of about 224 MB/s.

This is a strong result for a mechanical-drive setup, reflecting efficient caching and balanced SATA bandwidth. SMB Multichannel and link aggregation are supported, though the CPU’s available PCIe lanes limit simultaneous dual-port saturation. Even so, the system handles multiple concurrent transfers and backups without a noticeable decline in throughput.

Testing with NVMe SSDs improved overall responsiveness considerably. The three M.2 2280 PCIe 3.0 x1 slots each sustained sequential transfer rates between 800 and 900 MB/s, allowing the NAS to maintain a high level of random IOPS for metadata-heavy workloads. When used as cache devices, these drives accelerated small-file transfers and application access times, especially when paired with the system’s 16GB of DDR5 memory.

TerraMaster’s TOS 6 supports flexible use of these drives, enabling independent storage pools or hybrid cache layers, depending on the task. In sustained transfers over SMB and iSCSI, the system achieved write speeds close to 950 MB/s and reads near 1020 MB/s when using SSD-based arrays, validating the advantage of dual 5GbE interfaces for all-flash or mixed-tier environments.

Power consumption during operation remained modest, aligning with the platform’s efficient design. With no hard drives installed and three SSDs active, idle draw measured around 13.3 watts. Adding four 7200 RPM HDDs increased idle power to 55 watts and full-load consumption to roughly 61–63 watts under concurrent read/write activity. These figures indicate a well-balanced design that prioritizes power efficiency without restricting performance. Fan speed settings affect both thermals and acoustics predictably: in low-speed mode, the NAS operated near 33 dB(A), while mid and high-speed profiles raised that figure to 37 and 39 dB(A) respectively. During heavy disk operations, readings peaked briefly at around 43 dB(A), which is reasonable given the metal chassis and high-RPM drives used in testing.

Thermal results further underscored the system’s stability. Surface readings from the aluminum body remained between 25°C and 27°C on average, while drive bays hovered at 28–30°C after extended workload sessions. The rear fan exhaust area reached approximately 36–38°C under sustained load. The efficient heat dispersion of the chassis prevented thermal throttling during prolonged transfers or virtualization testing, even with all seven storage devices active. This consistent temperature range indicates that TerraMaster’s choice of single-fan cooling and full-metal housing achieves a practical balance between noise, airflow, and longevity.

The F2-425 PLUS includes 8 GB of DDR5, while the F4-425 PLUS doubles this to 16 GB, both expandable up to 32 GB. DDR5 provides higher bandwidth and reduced latency, which benefits multitasking environments, particularly when running Docker containers, multiple user sessions, or AI-driven indexing services such as local photo recognition. This upgrade positions the new PLUS series closer to the performance levels found in more expensive NAS systems while maintaining efficient power draw and thermal output. In terms of storage capacity, the F4-425 PLUS can house up to four 3.5-inch or 2.5-inch SATA drives, while the smaller F2-425 PLUS accommodates two. Both models also integrate three M.2 NVMe slots, allowing up to 8 TB per SSD and enabling users to reach a maximum combined capacity of approximately 144 TB in the four-bay model. Terramaster’s hybrid storage design allows these NVMe drives to serve either as a dedicated storage pool or as cache acceleration for HDD volumes, giving users flexibility to prioritize capacity or performance. The inclusion of three M.2 slots is unusual at this price tier and stands out against most two- and four-bay competitors, which typically provide only two.

For network connectivity, Terramaster has equipped both models with dual 5 GbE ports. This configuration effectively doubles the throughput available in the previous 2.5 GbE generation and can deliver an aggregated bandwidth of up to 10 Gbps through link aggregation. Although the lack of a dedicated 10 GbE port might limit direct single-link transfers, the two 5 GbE ports provide redundancy, failover, and multi-user performance advantages. Both models also include a front-mounted USB-C port and rear USB 3.2 Gen 2 Type-A connectors for high-speed external backups and peripheral connections, reflecting a refinement in Terramaster’s chassis design compared with earlier models that relied solely on rear ports.

Cooling and chassis design remain consistent with Terramaster’s recent metal-based enclosures, using active fan ventilation with independent drive bay access. The F4-425 PLUS features dual rear fans to maintain airflow across four bays, while the F2-425 PLUS employs a single high-efficiency unit. The new layout provides improved front-to-rear ventilation and easier access to drive trays. Internally, the systems do not include a PCIe expansion slot, which limits the potential for GPU or high-speed NIC upgrades but simplifies internal lane allocation for the CPU’s nine available PCIe lanes. Terramaster appears to have distributed these lanes between the three M.2 interfaces and dual network controllers to maintain balanced throughput across all functions.

How the F4-425 PLUS Compares with QNAP TS-464 and Synology DS425+

The QNAP TS-464 is built around the Intel Celeron N5095, a 4-core, 4-thread processor that can boost up to 2.9 GHz, and ships with 8 GB of DDR4 memory. It supports four SATA bays plus M.2 expansion and includes dual 2.5 GbE ports that can be aggregated for improved bandwidth. QNAP’s system benefits from a mature software ecosystem, offering HDMI output, virtualization support, and extensive backup tools. In performance testing, it delivers sequential speeds around 560 MB/s under RAID 5, limited mainly by network bandwidth. Compared with the F4-425 PLUS, the TS-464 offers stronger software flexibility and PCIe expandability, but its networking hardware is slower and it relies on older memory standards.

The Synology DS425+ takes a more conservative hardware route, using the Intel Celeron J4125 with four cores running at 2.0 GHz base and 2.7 GHz burst. It includes 2 GB of DDR4 memory, expandable to 6 GB, and offers one 2.5 GbE port alongside a 1 GbE port. Two M.2 NVMe slots are available but only for cache acceleration, not full storage pools. Sequential throughput typically reaches about 280 MB/s for reads and writes. Against the F4-425 PLUS, Synology’s system trails in memory, raw processing speed, and throughput potential, but maintains an advantage in software polish and long-term reliability through DSM integration.

In side-by-side terms, the F4-425 PLUS aims for a higher performance envelope. Its dual 5 GbE ports deliver aggregate throughput potential far beyond both the QNAP and Synology options, and its DDR5 memory with three M.2 NVMe slots allows flexible caching or tiered storage setups uncommon at this price tier. The trade-off lies in expandability and software maturity, where QNAP’s platform remains more modular and Synology’s DSM ecosystem offers more stability. For users focused on performance-per-dollar, the F4-425 PLUS introduces hardware that surpasses both competitors on paper, though long-term evaluation will depend on software development under TOS 6.

Terramaster TOS 6 Software

The F2-425 PLUS and F4-425 PLUS both ship with TOS 6, Terramaster’s latest operating system that replaces the earlier TOS 5 platform across its new generation of NAS hardware. TOS 6 introduces a redesigned interface with improved responsiveness and a more modular layout intended to reduce latency during multitasking.

It expands Terramaster’s range of built-in applications to include enhanced TRAID and TRAID+ hybrid array configurations, snapshot scheduling, and real-time data synchronization features. Backup utilities such as Duple Backup, Centralized Backup, TerraSync, and CloudSync provide integration across local drives, offsite NAS devices, and major cloud providers. The system also integrates hardware-assisted AES-NI encryption, supporting secure data transmission over 256-bit TLS and optional two-factor authentication. Although its design remains more lightweight than QNAP’s QTS or Synology’s DSM, it is notably faster to load and more accessible to new users.

Beyond core management tools, TOS 6 also incorporates AI-assisted photo management and multimedia indexing designed to run locally rather than relying on external cloud resources. Its facial, object, and scene recognition algorithms operate entirely on the NAS, avoiding external data transfers while maintaining privacy for personal collections. The OS additionally supports Docker and VirtualBox, enabling light virtualization tasks or deployment of third-party services without command-line setup.

Multimedia servers such as Plex, Emby, and Jellyfin can use Intel’s integrated graphics for hardware decoding, improving playback efficiency in 4K and 8K environments. While TOS 6 still trails mature ecosystems in app diversity, it delivers steady progress toward matching more established competitors, particularly for backup, synchronization, and AI-driven photo organization.

Verdict? The New4-Bay NAS Score to Beat?

The Terramaster F2-425 PLUS and F4-425 PLUS introduce a considerable upgrade to the company’s mid-tier NAS range, setting new expectations for what users can expect at the $400–$600 level. Both models adopt the Intel N150 processor, DDR5 memory, and dual 5 GbE networking, bringing performance that previously required higher-priced hardware. The F4-425 PLUS, in particular, combines four SATA bays with three M.2 NVMe slots, creating one of the most storage-flexible designs in its category. This configuration makes it a practical option for users who require hybrid pools or tiered caching but prefer to remain within consumer-level power and cost limits. Terramaster’s decision to include high-speed networking and DDR5 support at this price point demonstrates an emphasis on raw throughput and bandwidth efficiency, although it comes at the expense of PCIe expandability. From a broader market perspective, the F4-425 PLUS positions Terramaster competitively against alternatives from QNAP and Synology, trading ecosystem maturity for stronger base hardware. TOS 6 continues to evolve, offering usable AI-based media tools, secure backup systems, and local synchronization features. The platform still lacks some advanced management functions and third-party integrations seen in more established ecosystems, yet it now provides sufficient stability and depth for both professional and enthusiast users. Overall, the F4-425 PLUS presents an incremental but strategically significant advancement in Terramaster’s NAS design philosophy, marking a shift toward higher efficiency and versatility within its compact, consumer-oriented systems.

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.

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.

The UNAS 4 NAS

4-Core ARM, 4GB RAM, 1X 2.5GbE PoE+++ (TBC), 4x SATA Bays, 2x M.2 Bays (trays required), Power Over Ethernet delivery (PoE+++ Adapter Included) $379 – HERE

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.

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.

Quick Summary of the Synology DS1825+ NAS

Synology DS1825+ NAS Review HERE

The Synology DS1825+ is an 8-bay desktop NAS that marks a significant shift in the company’s approach to hardware and compatibility. Equipped with the AMD Ryzen Embedded V1500B processor—a 4-core, 8-thread chip running at 2.2GHz —this system balances power efficiency with performance across general file operations, virtualization, and media hosting. It includes support for up to 32GB of ECC DDR5 memory (2x SODIMM, arriving with 8GB by default), two M.2 NVMe slots for Synology-only SSD caching, and an onboard 10GbE port alongside three USB 3.2 Gen 1 ports. However, Synology’s controversial locked ecosystem continues here, restricting users to only Synology-branded drives for full support and access to storage pools, along with limited use of the NVMe bays strictly for cache, not storage.

While its internal hardware is more capable than previous Plus series models, the DS1825+ removes several features seen in past units. By default, it arrives with 2x 2.5GbE network ports, with the option to scale upto 10GbE with the use of a 1st party upgrade PCIe card, but at this pricepoint many users wuld expect 10GbE as standard. The shift to DSM 7.2 brings a refined software experience, including native Active Backup for Business, Hyper Backup, Surveillance Station, and full Docker support. However, DSM’s increasing reliance on Synology’s own hardware and subscription services, such as C2 Surveillance Proxy and Synology Drive Server, makes it harder for users to customize or expand without sticking to Synology’s ecosystem. Overall, the DS1825+ is best suited for users who want an integrated, secure, and reliable NAS experience with minimal manual setup, provided they are comfortable with the tighter hardware constraints.

Quick Summary of the UGREEN DXP8800 PLUS NAS

UGREEN DXP8800 PLUS NAS Review HERE

The UGREEN DXP8800 Plus is an 8-bay NAS solution that positions itself as a powerful, open-platform alternative for users seeking greater control over hardware and software customization. At the heart of the system is the 8-core, 16-thread Intel Core i5-1235U processor, paired with 8GB of DDR5 memory (expandable up to 64GB), but lacks support for ECC memory. Unlike its Synology counterpart, the DXP8800 Plus supports a much wider range of third-party hard drives and SSDs, and offers 2x Gen 4×4 M.2 NVMe slots that can be used not only for cache but also for primary or tiered storage, depending on the user’s operating system. This flexibility is backed by a user-serviceable layout and BIOS access, which allows full compatibility with alternative NAS OS options such as TrueNAS SCALE, UnRAID, or OpenMediaVault.

Connectivity is another area where the DXP8800 Plus stands out. It features two native 10GbE (RJ45) ports, two 2.5GbE ports, and dual USB4/Thunderbolt 4 ports, dramatically expanding external storage, docking, and display capabilities. This, combined with onboard HDMI output and front-accessible USB 3.2 ports, makes it far more versatile for media creation, backup workflows, and even lightweight workstation use. However, the DXP8800 Plus does not come with a polished first-party NAS operating system—UGREEN’s UGOS Pro remains in early stages, and lacks many of the mature backup, surveillance, and cloud services found in DSM. As such, the DXP8800 Plus is ideal for tech-savvy users who value open architecture, higher hardware flexibility, and self-managed software ecosystems over out-of-the-box turnkey simplicity.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Design and Storage

The Synology DS1825+ maintains the familiar chassis style used in the Plus series, combining functionality with conservative aesthetics. It features a full-sized 8-bay front panel with lockable trays, designed for tool-less insertion of 3.5” SATA drives and optional 2.5” adapters. The main body is a mix of steel and plastic, with a focus on rigidity and reduced vibration. The system lacks any onboard display or LCD, offering only basic LED indicators for system status, drive activity, and alerts, which may frustrate users seeking at-a-glance diagnostics. Access to internal components like the DDR5 ECC RAM and dual M.2 NVMe slots requires removing the top cover and internal caddy brackets, which isn’t as straightforward as it could be—especially given that the NVMe slots are only usable for cache and require Synology-branded drives. Thermal management relies on dual 120mm rear-mounted fans, which operate quietly but are non-replaceable without voiding warranty due to the proprietary fan harness. Physically, the NAS is slightly larger than competing 8-bay units and lacks rubberized feet or vibration isolation, which may be relevant for users placing it on shared work surfaces or desks.

The UGREEN DXP8800 Plus delivers a contrasting design focused on space efficiency, cooling, and user-accessibility. The NAS is housed in a durable metal shell with perforated side panels and a high-density internal structure. Despite its smaller footprint, it manages to accommodate eight SATA bays, two 4X4 M.2 NVMe slots, two SODIMM slots, and active cooling—all while remaining user-serviceable with just a standard screwdriver. The hot-swap trays are spring-loaded and support tool-less 3.5” drives or 2.5” drives via included screws. Access to RAM and SSD slots is streamlined through a simple internal partition design that doesn’t require full disassembly, making upgrades significantly faster than on the DS1825+. The rear exhaust fan is larger than expected for a device this compact, and although thermals are generally within acceptable limits, our testing showed that M.2 SSDs running at PCIe Gen 3 speeds did reach over 65°C during sustained I/O, especially when mounted without aftermarket heatsinks. Unlike Synology, UGREEN includes front-mounted USB 3.2 Gen 2 ports (Type-A and Type-C), ideal for creators and users who frequently move large projects or footage onto the system using direct-attached storage.

When it comes to storage flexibility, the differences are stark. Synology’s DS1825+ enforces a strict hardware compatibility policy, where only Synology-certified HDDs (such as the HAT5300) and SSDs (SAT5200 or SNV3410/3510) are officially supported. Drives outside this list may trigger warnings, be ineligible for pools, or lose access to SMART health readings. NVMe drives cannot be used for storage volumes at all and are locked to caching roles only. These restrictions are enforced by DSM 7.2+ and persist even with the system fully updated.

By contrast, the UGREEN DXP8800 Plus places no such limits. Any SATA or NVMe drive can be used, and users can create pools across mixed-capacity and mixed-brand disks, including enterprise-grade drives. Storage volumes can be configured freely in supported OS environments, and the two M.2 slots can act as primary storage, tiered ZFS vdevs, or cache depending on the OS—TrueNAS SCALE, for instance, recognized all M.2 drives and allowed custom pool creation without issue. This makes UGREEN’s system more attractive to users with existing drives or specific ZFS/Btrfs layouts in mind.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Internal Hardware

he Synology DS1825+ is built around the AMD Ryzen V1500B processor, a 4-core, 8-thread embedded SoC designed specifically for NAS and server workloads. With a fixed base clock of 2.2GHz and no boost functionality, this Zen-based CPU focuses on stability, multi-threaded efficiency, and low power consumption, making it well-suited for consistent background operations like file serving, multi-client backups, and large-scale storage array management. The chip includes AES-NI support for hardware encryption acceleration and offers full compatibility with DSM’s virtualization stack, including Docker and Synology’s Virtual Machine Manager. However, the V1500B lacks an integrated GPU, and the DS1825+ does not support hardware transcoding, making it unsuitable for Plex or media applications that rely on real-time video encoding unless offloaded to cloud services like Synology C2. It’s a reliable and mature processor choice, albeit one that prioritizes stability over flexibility or raw speed.

The DS1825+ ships with 8GB of ECC DDR4 memory (1x SODIMM) installed, with support for up to 32GB across two slots, and ECC is supported on both official and some compatible third-party modules. The internal layout, however, is relatively restrictive. The memory and M.2 slots require tray removal and partial disassembly to access. Synology includes two M.2 NVMe slots that operate at PCIe Gen 3×4, but DSM only allows them to be used for read/write caching and only with Synology SNV3410 or SNV3510 SSDs. These slots are not available for storage pool creation or system boot, regardless of the SSD used. There is no PCIe slot or BIOS access, making this a closed system that enforces Synology’s validation model tightly. While this approach ensures stability, it limits performance tuning and locks users into higher-priced branded components.

The UGREEN DXP8800 Plus uses an Intel Core i5-1235U, a hybrid 10-core (2 performance, 8 efficiency), 12-thread mobile CPU built on the Alder Lake-U architecture. With a boost clock up to 4.4GHz and integrated Intel Xe graphics, it offers both multi-threaded efficiency and hardware video transcoding support via Quick Sync. This is ideal for users running Plex, Jellyfin, or AI-based video analysis locally. The system ships with 8GB of non-ECC DDR4 memory, expandable to 64GB, using standard SODIMM slots. UGREEN’s internal board features 2x M.2 NVMe slots operating at PCIe Gen 4×4 speeds, offering significantly more bandwidth than Synology’s Gen 3 slots. These SSDs can be used for boot, storage pools, or cache, and the system supports a wide range of third-party drives without warnings or restrictions. BIOS access is fully available, allowing installation of operating systems like TrueNAS, UnRAID, or Proxmox. UGREEN’s internal hardware favors openness and customizability, providing users with direct control over performance, expansion, and component choice—at the cost of requiring more technical expertise.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Ports and Connections

The Synology DS1825+ delivers a modest and business-focused range of connectivity options, designed primarily for reliability and integration within an IT-managed environment. It includes 2x 2.5GbE RJ-45 LAN ports, offering basic link aggregation or dual-network failover functionality. While this offers faster-than-Gigabit throughput, the lack of 10GbE out of the box may be limiting for users working with large media files or virtualization workloads, particularly in comparison to other 2025 systems.

The system provides 3x USB 3.2 Gen 1 (5Gbps) Type-A ports, all located on the rear, suitable for UPS integration, external storage, or compatible backup devices. In terms of expansion, Synology includes 2x USB Type-C ports, but these are reserved exclusively for connecting official DX525 expansion units. They do not support data transfer, peripherals, or USB-C accessories and serve only as proprietary expansion interfaces. No HDMI, DisplayPort, or audio outputs are included, and there is no SD card reader. This reinforces Synology’s design philosophy: operate headlessly, manage remotely, and keep the system within the bounds of their validated ecosystem.

In contrast, the UGREEN DXP8800 Plus positions itself as a fully-featured, hybrid-use NAS platform with wide-ranging I/O options for prosumers and professionals. It features 2x 10GbE RJ-45 LAN ports—a clear advantage over Synology’s 2.5GbE setup—offering significantly more bandwidth for media editing, VM hosts, or multi-user environments. On the front, UGREEN includes 2x Thunderbolt 4 (40Gbps) ports, which double as high-speed USB-C for peripherals, external drives, or even eGPU enclosures in supported OS setups. The rear provides 2x USB-A ports at 10Gbps, plus 2x USB 2.0 ports, allowing backward-compatible peripheral support. For display, the system includes 1x HDMI port with 8K output support, connected via Intel’s Xe iGPU, as well as a high-speed SD 4.0 card reader—a particularly valuable addition for content creators offloading camera media directly to the NAS. There is also a PCIe x4 slot for optional hardware expansion. This broad I/O layout enables the DXP8800 Plus to function as a headless NAS, a media server, or even a workstation replacement, depending on the OS you choose to run.

The gap in connectivity between these two NAS systems reflects their broader design philosophies. Synology has deliberately kept the DS1825+ minimal, standardized, and tightly integrated with its ecosystem, which enhances long-term support and serviceability but limits flexibility. UGREEN, on the other hand, offers extensive general-purpose ports that cater to a wider range of workflows—especially for users running Windows, Proxmox, TrueNAS, or virtualized environments. Whether it’s direct media ingestion via SD card, high-speed expansion through Thunderbolt, or dual 10GbE networking, the DXP8800 Plus outpaces the DS1825+ in almost every I/O category. However, this flexibility comes with the expectation that the user is comfortable with open-platform system management and a DIY-style deployment model.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Software and Services

The Synology DS1825+ runs on DSM 7.2, Synology’s mature and widely respected NAS operating system. DSM offers a broad ecosystem of native applications and services, including advanced storage management, multi-tiered backup solutions, virtual machine hosting, and comprehensive multimedia support. Key built-in tools such as Synology Drive, Hyper Backup, Active Backup for Business, Surveillance Station, and Synology Photos provide enterprise-grade data handling in a highly polished interface.

DSM also includes Snapshot Replication with Btrfs, granular folder/file-level restore, and Active Directory integration. Importantly, DSM supports features like Windows ACL permissions, Samba v4, WORM file locking, and two-factor authentication by default, with Synology’s C2 platform offering cloud sync, identity management, and secure backup options. However, DSM has increasingly tied deeper functionality (e.g., certain security tools and snapshots) to Synology-branded storage and expansion hardware, with third-party drive warnings now appearing by default.

UGREEN’s DXP8800 Plus runs UGOS Pro, a Linux-based operating system developed in-house. Now one year into active deployment, UGOS Pro has matured substantially with ongoing updates and wider feature support. The interface is clean and web-accessible, and recent updates have added core NAS functions previously missing. As of the latest firmware, Docker, virtual machine creation, and Jellyfin media server are all natively supported via one-click installs.

Importantly, iSCSI support was also added, addressing a key omission for enterprise or VMware users. 2-factor authentication (2FA) is now present, and security protocols include IP/MAC-level blocking, custom firewall rules, and access control policies. While UGREEN still lacks the depth of anti-ransomware protection found in DSM or QNAP’s QuFirewall, the fundamentals have improved dramatically. Local-only AI services for photo indexing and object recognition have also been refined, with user-selectable models running without internet access.

Where DSM excels in deep integration and business-class reliability, UGOS Pro stands out for its openness and responsiveness to user feedback. Users can enable SSH, customize OS-level settings, and even install TrueNAS, UnRAID, or Proxmox without voiding the warranty, as UGREEN has opted for an open-platform approach.

UGOS also supports Windows file services (SMB), NFS, and web-based file managers, though its permissions system and UI are still somewhat basic compared to DSM. Synology’s first-party software tends to offer higher polish, more documentation, and broader cross-platform support, particularly in cloud-integrated services, whereas UGOS is catching up in functional breadth but remains relatively limited in automation and long-term software ecosystem depth.

Both platforms include mobile apps and browser-based remote access, but Synology’s remote access via QuickConnect is significantly more user-friendly and secure out-of-the-box, while UGREEN’s remote services are best replaced or supplemented by Tailscale, Cloudflare Tunnel, or similar tools. Synology’s Surveillance Station also has years of development behind it with support for hundreds of IP cameras, whereas UGREEN does not yet include native surveillance software in UGOS Pro.

For users seeking a media-focused setup, UGOS offers a good local multimedia experience via Jellyfin, while DSM supports Plex and Video Station (with transcoding limitations depending on CPU). Ultimately, Synology’s DSM remains the more robust, enterprise-ready option, while UGOS Pro presents a highly promising and increasingly competitive open alternative that still favors self-managed users.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Verdict and Conclusion

The Synology DS1825+ remains a compelling choice for users prioritizing reliability, software integration, and long-term support.

The Synology DS925+ versus QNAP TS-464 – Buy NEW or Buy QNAP?

Every so often in the NAS market, a new model arrives that challenges not just its predecessors but also its closest competitors. With the 2025 release of the Synology DS925+, buyers now face an interesting dilemma: go with Synology’s latest compact powerhouse, or choose QNAP’s TS-464—a device that has already proven itself since its release in 2022/2023 and offers a wide array of features at a competitive price. The DS925+ brings notable upgrades to CPU architecture, system memory scalability, and integration within Synology’s tightly controlled ecosystem. Meanwhile, the TS-464 has spent years benefiting from firmware maturity, PCIe expandability, and a more open hardware approach that appeals to power users and tinkerers alike. But which device is ultimately the better buy in 2025? Should you embrace Synology’s ecosystem with its newer, high-performance release, or does QNAP’s more versatile and budget-friendly offering still hold strong in the face of newer competition? Let’s dive into the details to help you decide which NAS deserves your next investment.

Synology DS925+ vs QNAP TS-464 – Hardware Specifications

When placing the 2025 Synology DS925+ alongside the 2022/2023 QNAP TS-464, one might expect the newer model to clearly dominate in every area. But hardware comparisons in the NAS market are rarely so simple. While both units are aimed at tech-savvy home users and small businesses looking for reliable, always-on storage solutions, their approaches to hardware—and the user needs they prioritize—are noticeably different. The DS925+ emphasizes streamlined performance, reduced noise, and integration within Synology’s tightly managed ecosystem. The QNAP TS-464, meanwhile, leans into raw hardware flexibility, DIY expandability, and a more open feature set for power users. Below is a detailed hardware breakdown of both NAS devices, showing where each shines and where compromises were made.

The DS925+ delivers a refined hardware experience out of the box, with its newer AMD Embedded Ryzen V1500B 4 Core/ 8 thread processor, dual 2.5GbE ports for faster LAN connectivity, and modern I/O including USB-C. It features two M.2 NVMe slots (for cache only, unless you use the Synology SNV3400 drives from Synology), dual memory slots supporting up to 32GB of ECC DDR4 RAM, and a compact metal chassis designed for quiet, efficient operation. It also runs cooler and quieter than many of its rivals, making it an ideal fit for environments where noise levels matter—such as living rooms, home studios, or small offices. This makes the DS925+ a “plug-and-play” NAS with premium internal components and minimal need for user intervention.

By contrast, the QNAP TS-464 takes a more modular, expandable approach. Powered by the Intel Celeron N5105/N5095 CPU (a quad-core processor with integrated graphics, but only 4 threads), it offers HDMI 2.0 output, two M.2 PCIe Gen3 x1 slots (which can be used for either caching or storage pools), and a PCIe Gen3 x2 slot for optional 10GbE or more M.2s, USB expansion, or even GPU cards. QNAP also includes dual 2.5GbE ports, putting it on par with the DS925+ in terms of network speed, but it edges ahead in overall hardware adaptability. Want multimedia output via HDMI? QNAP has it. Want to add NVMe storage pools or real-time transcoding? QNAP supports that too. That said, the TS-464 is based on a slightly older CPU architecture, lacks ECC memory support, and typically generates more fan noise under load. Additionally, its OS and ecosystem are broader in scope but often require more manual setup. Ultimately, the DS925+ is purpose-built for those who prioritize a quiet, polished, and simplified experience with modern performance. The TS-464, on the other hand, remains an excellent choice for users who prefer control, multimedia support, and greater hardware flexibility. Choosing between them largely depends on whether you value Synology’s stability and turnkey design, or QNAP’s freedom and potential.

AMD V1500B vs Intel N5105 – CPU Specifications (Synology DS925+ vs QNAP TS-464)

In any NAS system, the processor plays a pivotal role in determining the scope of functionality—whether it’s managing multiple concurrent users, running virtual machines, powering AI-driven applications, or simply handling encrypted transfers and background tasks efficiently. The Synology DS925+ and the QNAP TS-464 take noticeably different approaches in this regard. The DS925+ features the AMD Ryzen Embedded V1500B, a server-grade SoC designed for sustained multi-threaded workloads. The TS-464, on the other hand, runs on the Intel Celeron N5105, a more consumer-oriented chip that prioritizes integrated multimedia support and power efficiency. While both CPUs are quad-core, their architecture, instruction set, and target use cases diverge sharply—affecting not only raw processing, but also the capabilities unlocked within DSM and QTS/QuTS, respectively.

In terms of raw specs, the V1500B offers 4 cores and 8 threads with a base clock of 2.2GHz and support for ECC memory—a key advantage for mission-critical environments. This CPU is built for multitasking and thrives in scenarios involving virtual machines, container services, and intensive file indexing or backup operations. As a result, the DS925+ supports up to 8 concurrent virtual machines, 8 virtual DSM instances, and higher thresholds for connected users across Synology apps. It is better suited to offices or power users who rely on services like Synology Office, Drive, or Surveillance Station running in tandem. The system handles up to 150 Synology Chat users, 80 Office users, and 80 Drive users, offering excellent multitasking performance with low overhead.

The QNAP TS-464’s Intel N5105 is a 10nm Jasper Lake processor, also quad-core but without hyper-threading and with a slightly lower base clock (2.0GHz). However, it includes integrated Intel UHD Graphics, giving it one key advantage the DS925+ lacks: hardware-accelerated video transcoding via QNAP’s own QuMagie, Video Station, and especially Plex Media Server with support for on-the-fly 1080p and 4K decoding when paired with proper client-side licensing. This makes the TS-464 ideal for multimedia-heavy environments. Beyond media, the N5105 powers QTS and QuTS hero with access to QNAP’s broader and often more modular ecosystem. This includes Hybrid Backup Sync (HBS 3) for unified backup and disaster recovery, QuDedup for deduplicated snapshot replication, QVR Elite and QVR Pro for professional-grade surveillance (supporting multiple IP camera licenses natively), and AI Core features like face recognition and event detection when paired with the QuMagie or QVR Human apps. The TS-464 also supports Virtualization Station, enabling users to run lightweight Linux or Windows VMs with direct passthrough access to USB or PCIe devices, and Container Station, which offers both Docker and LXC container compatibility with GPU passthrough for NPU-based AI inference workloads. Thanks to the included PCIe Gen 3 x2 slot, the system supports optional upgrades like 10GbE NICs, QM2 expansion cards (for M.2 SSD or additional 2.5GbE/10GbE ports), or even Wi-Fi 6 cards, something entirely absent in the DS925+. Additionally, QNAP allows direct output to an external display via HDMI 2.0, enabling standalone use of HD Station apps like Chrome, LibreOffice, Kodi, and even Linux desktop environments — a feature highly prized in HTPC and security NVR deployments. Users can leverage Linux Station to run full Ubuntu VMs locally, or install Ubuntu Core through the App Center for custom development or edge AI inference scenarios.

Taken together, the TS-464 may not support the same high virtual machine/user count as the DS925+, but it compensates with a broader set of integrated appliances catering to power users, home labs, edge AI, and media-heavy deployments. It’s a more “tinker-friendly” platform, favoring flexibility and breadth over centralized system control and vertical integration. If you need an appliance that works across entertainment, security, and hybrid cloud workflows, with room for add-on functionality via hardware or apps, the TS-464 is hard to beat for the price. That said, the Synology DS925+ ultimately offers greater headroom for enterprise workflows, heavier VM usage, and large-scale hybrid deployments. It sacrifices media transcoding and graphical acceleration, but gains a server-class CPU that ensures consistent performance under heavier load conditions. Meanwhile, the TS-464 excels in edge-case versatility, offering more multimedia flexibility and richer expansion potential via PCIe. If your priorities lie in business-class performance, ECC memory support, and robust multi-user capacity, the DS925+ is the clear winner. But for media streaming, home lab tinkering, and a wider hardware feature set, the TS-464 remains a very compelling alternative.

Synology DS925+ vs QNAP TS-464 – Software Specifications

When it comes to NAS platforms, hardware is only half the story—what truly determines a system’s long-term value is the strength, maturity, and flexibility of its software. Synology’s DSM (DiskStation Manager) and QNAP’s QTS/QuTS Hero are two of the most advanced NAS operating systems available today, offering extensive suites of services for backup, virtualization, hybrid cloud, media streaming, and AI-assisted surveillance. But while both OS platforms cover similar ground, their design philosophies, application depth, and supported workloads differ substantially. The Synology DS925+ and QNAP TS-464, though comparable in price and both aimed at prosumers and SMBs, unlock very different software experiences depending on the deployment goals—be it centralized IT infrastructure, media-rich home labs, or container-based edge computing.

With the DS925+, Synology leans into its strength in unified management and vertical integration. DSM 7.2 is optimized for reliability, simplicity, and scalability within Synology’s ecosystem. The DS925+ supports up to 8 virtual machines and 8 Virtual DSM instances through Virtual Machine Manager, offers extensive group and user quotas, and enables full integration with Synology’s cloud services (such as Synology C2 Backup, C2 Identity, and Hybrid Share). Its higher hardware ceiling allows for more active users: 150 on Synology Chat, 80 on Synology Drive and Office, and up to 8 simultaneous VPN connections. Backup capabilities are similarly robust, with a higher threshold of shared folder sync tasks and superior support for incremental snapshot replication. Surveillance Station on the DS925+ supports up to 40 IP cameras and benefits from reduced CPU overhead during continuous recording, even while handling concurrent backup or media indexing operations. DSM’s elegant UI, consistent updates, and tightly integrated packages make it ideal for organizations that value centralized IT administration and long-term platform stability.

On the other hand, the QNAP TS-464 running QTS 5 or QuTS Hero offers a more open and modular software ecosystem. While the Intel N5105 CPU imposes lower multitasking ceilings than the V1500B, QNAP compensates with a broader set of feature-specific applications and customization paths. The TS-464 supports virtualization through Virtualization Station (for VMs) and Container Station (for Docker + LXC), and unlike the DS925+, can output video directly via HDMI 2.0—allowing the NAS to act as a standalone Linux desktop, NVR, or HTPC via HybridDesk Station. QNAP also differentiates itself with Hybrid Backup Sync (HBS3), which enables multi-destination sync, deduplicated backup via QuDedup, and real-time disaster recovery tools not found in DSM. QVR Pro and QVR Elite offer an expansive surveillance suite with optional AI-powered analytics (e.g., face recognition, people counting) when paired with compatible QNAP AI apps. The inclusion of ZFS with QuTS Hero (an optional OS for the TS-464) enables inline compression, self-healing file systems, and block-level snapshots, which can be critical for data integrity in business scenarios.

QNAP also encourages expansion through its App Center, which includes over 150+ native and third-party apps, from Node.js and GitLab to Home Assistant, Ubuntu Station, and even Mattermost for self-hosted chat. While the system supports fewer concurrent users and VMs than the DS925+, its strength lies in feature breadth and system-level flexibility. Add-ons like 10GbE NICs, QM2 SSD accelerators, or Wi-Fi 6 cards via PCIe further extend its versatility, especially for hybrid edge workloads or multi-role deployments that evolve over time. In short, the Synology DS925+ is designed for administrative simplicity and long-term scaling, excelling in consistent performance across multi-user deployments with deep DSM integration. The QNAP TS-464, meanwhile, is a powerful sandbox for customization, offering greater freedom, multimedia functionality, and third-party integration—at the cost of some operational polish and software limits. Choosing between them depends on whether your priorities lie in predictable enterprise-grade execution or a more adaptable, feature-dense platform.

Synology DS925+ vs QNAP TS-464 – Hard Drive and SSD Compatibility

In 2025, Synology has taken its most aggressive step yet toward locking down hardware compatibility, and nowhere is this more evident than in the DS925+. Following years of gradual restrictions—starting with warnings for unverified drives and progressing to default white-listing only Synology-branded media—the DS925+ now represents a firm line in the sand. At the time of writing, this system will not allow DSM initialization if it detects hard drives or SSDs that are not officially listed on Synology’s compatibility list. This list includes exclusively Synology HAT5300/HAT3310 HDDs and SAT5200 SSDs, with no third-party Seagate, WD, Toshiba, Samsung, or Kingston media currently supported. Regardless of drive quality or performance, unsupported models will be outright blocked during system setup. While Synology claims this guarantees optimal reliability and performance within DSM 7.2, the move drastically reduces flexibility for users and integrators alike.

In stark contrast, the QNAP TS-464 embraces an open compatibility philosophy. It supports virtually all major consumer and enterprise drives—from Seagate IronWolf and Exos, to WD Red, Red Plus, and Ultrastar, as well as Toshiba N300/X300 and Samsung/Kingston SSDs—up to 24TB per drive (or higher as of late 2025). QNAP also maintains a regularly updated compatibility list, but crucially, this list is advisory rather than mandatory. Users can install any 3.5″ or 2.5″ SATA HDD/SSD, and as long as it meets the physical and electrical standards, the TS-464 will initialize without issue. This means integrators, home users, or small businesses can reuse existing drives or select from the most cost-effective options in their region—something that’s increasingly difficult to do on newer Synology units. Moreover, QNAP allows mixing and matching of drive brands and capacities within the same storage pool (especially under QuTS hero’s ZFS environment), giving users granular control over redundancy, performance tuning, and cache layering with non-proprietary M.2 NVMe SSDs. This openness also applies to QNAP expansion units, many of which continue to work even with completely mixed-brand storage configurations—something Synology’s newer expansion policies have started to restrict.

For users in regions where Synology-branded media is expensive, hard to find, or simply not justified for non-critical applications, this policy shift on the DS925+ can be a deal-breaker. It positions the system closer to an appliance model, where Synology controls not only the hardware and software, but the storage medium itself. While that vertical integration may improve long-term reliability for some enterprise users, it’s difficult to reconcile with the broader DIY NAS community that values choice and modularity. Ultimately, this creates a philosophical divide: QNAP remains open, modular, and adaptable, trusting users to make informed decisions about their storage media. Synology, in contrast, is consolidating control, with the DS925+ exemplifying a move toward a closed ecosystem—potentially alienating users who previously praised DSM for its balance of simplicity and flexibility. Prospective buyers need to weigh not just performance and features, but how tightly they want to be tied to a single vendor’s hardware roadmap.

Synology DS925+ vs QNAP TS-464 NAS – Which Should You Buy?

The Synology DS925+ is a 2025 refresh designed with clear intent: push performance, tighten control, and streamline the out-of-box experience. In contrast, the QNAP TS-464—released in late 2022—is a Swiss Army knife of NAS flexibility, packed with customization options, open compatibility, and enough horsepower to meet the needs of both power users and small business deployments. Choosing between them ultimately comes down to what kind of NAS experience you’re after: a controlled, polished, and tightly integrated environment, or an open, adaptable, and hardware-friendly platform. On raw performance, the DS925+ has the edge. Its quad-core, 8-thread AMD V1500B CPU delivers higher throughput for multitasking, virtual machines, and heavier concurrent services, and DSM’s user/service thresholds are notably higher as a result. Add in dual 2.5GbE ports by default, and it’s clearly a step ahead of the DS923+ predecessor 1GbE-only base configuration, and you are looking at a healthy upgrade in several ways in this refresh. However, QNAP claws back ground with its PCIe Gen3 x2 slot, allowing 10GbE upgrades, Wi-Fi cards, and even GPU acceleration in select use cases—something Synology removed entirely from the DS925+. In QNAP’s favor is also its support for real-time hardware transcoding, HDMI 2.0 video output, and direct-attached monitor access—making it a better fit for media-centric environments where local playback, Plex, or Kodi usage matters.

But perhaps the most significant dividing line is drive compatibility. The DS925+ will only initialize DSM with Synology-validated drives—locking out nearly all third-party HDDs and SSDs unless explicitly approved. This hardline stance means limited flexibility for users wanting to build using existing drives or regional market alternatives. Meanwhile, the TS-464 supports virtually all consumer and enterprise drives, from Seagate to Toshiba to Kingston, giving users total control over their storage budget and deployment roadmap. This open-ecosystem approach extends to M.2 NVMe usage too, where QNAP allows storage pool creation, caching, and tiering with off-the-shelf modules, while Synology restricts pool creation to only their branded NVMes. If you’re an IT administrator, content creator, or SMB looking for a polished, performance-forward NAS and you’re fully on board with Synology’s ecosystem—including its branded drives—then the DS925+ offers a streamlined, high-ceiling experience with excellent multitasking potential and cleaner UI/UX polish under DSM 7.2. But if you’re someone who values flexibility, upgrade paths, media support, or simply wants to control your storage choices without vendor lock-in, the QNAP TS-464 is an incredibly compelling alternative—offering strong performance for its price, an open architecture, and a deeper toolbox under QTS/QuTS Hero.

The Synology DS925+ is the better plug-and-play NAS for prosumers and SMBs who want a high-performance, low-maintenance experience—provided they’re comfortable buying into Synology’s tightly controlled ecosystem of software and storage hardware. On the other hand, the QNAP TS-464 remains the better choice for users who value flexibility, hardware freedom, and scalability—especially if media features, drive compatibility, or future upgrades are part of the plan. Ultimately, the DS925+ is the sharper tool, but the TS-464 is the more versatile one.

If Not Synology? Which Other NAS Brand Should You Choose?

It’s an odd question, but with Synology arguably making some rather higher business and enterprise decisions in recent years, there have been increasing queries about who would fill the void if they moved onwards and upwards. As Synology holds such a powerful position in the NAS market, their absence would certainly lead to quite the battle of strength from other players. The obvious answer would be QNAP, a brand that has a similar history to Synology (over two decades in the business, Taiwan-based, in-house OS, numerous 1st-party tools, home and business solutions, etc.), but in 2025, the reality is nowhere near as clear-cut. Younger established brands that have jockeyed for 3rd position, such as Asustor and Terramaster, have been challenged by several startups (ZimaCube and Zimaboard 2, Orico’s Cyberdata Vault, to name just two) entering the fray, as well as established brands like UGREEN, which are expanding their business into the NAS sector. If Synology, for whatever reason, ceased to occupy this important user class of private turnkey server ownership, who would be best placed to occupy it?

How, Where and Why Has Synology Changed?

Synology’s rapid change in business stance to be more enterprise/hyperscale-focused comes at the same time as their frequency of more entry-level, small business, prosumer, and enthusiast solutions has dropped. The regularity of smaller 2-Bay and 4-Bay solutions has noticeably decreased, and the hardware they feature has changed to accommodate more business-type use. This by no means suggests that the brand is making moves to exit these user groups (indeed, support of DSM and the latest revision DSM 7.2.2 extends to all existing users up to many systems released in the late 2010s). However, there has been plenty of user outcry from existing users and potential customers on the architecture of both DSM and the recent releases that exacerbate users to move away from the brand and spend their allocated budgets elsewhere. Synology still comfortably sits ahead of its competitors in terms of software, features, and the UX of their platform, but many changes in policy and support mentioned below have started this trend:

• Changes in 3rd-party HDD compatibility on systems above the 8-Bay scale, prioritizing their own 1st-party labeled HDDs and SSDs, as well as reducing the presentation and compatibility listings on their site significantly.
• Changes in the choice of internal hardware featured in their systems to be more focused on business file processes and less on multimedia use.
• Comparatively smaller increases in base hardware between refreshes of individual series (e.g., J4125 and V1500B CPUs in 2024 launch devices, despite first appearing in 2019/2020).
• Considerable increased focus on software enhancements over hardware (not a bad thing, but an undeniable fact).
• Increased proprietary hardware support over 3rd-party (e.g., Synology-only Memory modules, custom 10GbE adapters like the E10G22-T1, Synology-only M.2 SSDs for Pool Use).
• An increasing number of cloud subscription services getting newer features, while local services remain secure and stable but static.
• New product focus shifting towards newer larger-scale solutions like the evolving GridStation series, Active Protect subscription system, and C2 innovations.
• The predicted elimination of the J entry-level series in favor of the pre-populated and software-streamlined BeeStation.

All of the above are small factors in themselves, but add them all up, and you see small but important stepping stones toward a gear shift in Synology’s target demographic. So, if Synology were to intentionally or inadvertently begin to move outside of these user groups of home, small business, and enthusiast, who stands to fill this space and grow?

QNAP vs Synology?

As mentioned earlier, QNAP stands to be the most likely contender to fill this space. With over 20 years of history, a larger range of hardware solutions than Synology, and software that does pretty much everything Synology’s does, they have been consistent competitors. However, inconsistencies in user experience, conflicting UIs, and a tendency to try to do “too much” have resulted in their losing ground to Synology in terms of software. Add to this the negative brand impact of security incidents in 2020-2022, which tarnished their reputation around security and safety, requiring serious improvement. To the brand’s credit, they have made considerable internal culture changes on this subject, adding bounty programs, tightening system defaults, increasing pen testing, introducing several system security scanning tools, disabling things like SSH and admin super user accounts as standard, and more.

$189 on Amazon (Check Here)	$549 on Amazon (Check Here)	$2499 on Amazon (Check Here)

In terms of hardware, they have mostly stuck to what works, refreshing existing product families at the same rate of 2.5-3 years for desktop small-medium scale, and 3-5 years for larger scale. They have also introduced significantly more recent CPUs from both Intel and AMD, as well as 2.5GbE as standard on their solutions at the same price point as 1GbE. If it weren’t for the damaging brand harm caused by the Deadbolt/QSnatch/Qlocker ransomware attacks, I think Synology would have been significantly challenged by QNAP in the last 2-3 years across all fronts. However, the setback to QNAP’s reputation reduced this growth potential significantly, and in the last two years, we have seen an increasing number of new names pop up in NAS that have also harmed QNAP’s appeal to users in terms of hardware value, the thing they could always be relied upon to beat Synology on. QNAP would still stand to become the ‘top dog’ in the event of a Synology exit (Synexit?) from the low-to-medium tiers of NAS storage, but many new players have entered the field, such as…

UGREEN vs QNAP?

Largely known for their power adapters and PC accessories, a year ago UGREEN had practically no real presence in the world of NAS. They had a smaller scale and more entry-level range of solutions that were limited to the East, but aside from that, they were complete outsiders. Fast forward to now, and following a successful and well-marketed Kickstarter campaign that raised millions of dollars, they are now a provider of genuinely impressive turnkey NAS solutions—the NASync series. The key word there is “turnkey”, as in they are providing both the hardware and the software. They could have just rolled out their hardware and made it OS-free (i.e., “Here’s a ready-built server, now go install UnRAID or TrueNAS”), but instead, they opted to produce and include an impressively responsive NAS OS in UGOS. Genuinely challenging the feature set of the likes of Asustor and Terramaster, as well as the design of Synology and the hardware level of QNAP, UGREEN has made a rapidly growing name for itself in the small-to-medium NAS sector.

Value Series	Best All Rounder	Prosumer NAS

$399 on Amazon (Check Here)	$699 on Amazon (Check Here)	$1499 on Amazon (Check Here)

They definitely lack the range of solutions that those other brands offer, with only 6 solutions currently available (the DXP2800, DXP4800/PLUS, DXP6680, DXP8800, and DXP480T), and no rackmount solutions yet, but it’s a solid start. Equally, their software, although fluid and responsive in nailing down the NAS fundamentals, lacks many of the more impressive AAA+ solutions that are offered by the bigger brands. Lastly, although they raised a considerable sum during the crowdfunding, they do not have the global support, offices, or availability of their long-running NAS competitors—with solutions only being available in two regions, the US and Germany. All of these factors add up to a brand that is poised to make even bigger splashes in the years to come but is perhaps not quite ready to replace the big dog, Synology, just yet!

ASUSTOR vs Synology?

Always the bridesmaid, but never the bride, Asustor is a brand that has been around in the world of NAS in one shape or form for quite a few years. They are one of the mainstream Taiwanese brands in NAS that has always ‘been there’, but it is only in the last 4-5 years that they have been making sizable moves to take on both Synology and QNAP. One of the main ways in which they pursued this is by developing numerous features in both hardware and software that are available from their competitors individually. So features such as M.2 NVMe-focused storage systems, BTRFS support, WORM locking, 2.5GbE/5GbE support, HDMI output via a dedicated GUI, and more are features available on Synology and QNAP to some extent, but only Asustor rolls them under one brand umbrella. So, how poised are they to fill a void if Synology moved out of this space?

Well, from a hardware standpoint, Asustor is in a very good position. Them being Taiwan-based will certainly soothe concerns that have grown around Chinese companies and data storage solutions. Equally, their hardware has evolved rapidly in their last two generations to feature some genuinely unique solutions that are either specific to the platform or priced at a level that makes them genuinely competitive against DIY and BYO solutions. Systems such as the Flashstor series, Lockerstor series, and even value offerings like the Drivestor are surprisingly well equipped. They are not quite on the same level of hardware as QNAP (who have a significantly more diverse hardware portfolio), but they are fleshing it out very well.

Value Series	Best All Rounder	Prosumer NAS

$369 on Amazon (Check Here)	$449-749 on Amazon (Check Here)	$1999 on Amazon (Check Here)

However, it is the software of Asustor (ADM) that is unfortunately where the brand is a little more timid. They have a NAS OS, numerous client tools for Windows, Mac, iOS, and Android—and they nail down the bulk of the application fundamentals for storage management, multi-site backup handling, multimedia playback, containers, and more. But the platform lacks a few of the more AAA/desirable services, such as AI-powered photo recognition, a 1st-party VM tool, ZFS support, and ultimately is a little more reliant on 3rd-party applications to fill the gaps. They have recently countered this by officially detailing that they support users who buy Asustor hardware to go ahead and install 3rd-party NAS software like TrueNAS or UnRAID without it harming your warranty—so they know they are not leading the pack in terms of their own ADM NAS software but do make noticeable user concessions. With new hardware on the horizon in the Lockerstor Gen3 and Flashstor Gen2 (both of which see a significant bump in hardware profiles), we might see some impressive moves from Asustor in 2025. I just think they still have some ways to go before they can fill any potential void that Synology might leave.

TERRAMASTER vs Synology?

Terramaster has been jockeying for the NAS 3rd place spot with Asustor for well over a decade at this point, and much like their opponent, they have been good at integrating individual features from both QNAP and Synology into their own NAS hardware and TOS platform, but to a larger degree than Asustor. For example, their OS provides largely everything that Asustor ADM does (including TrueNAS/UnRAID support without voiding your warranty) but adds to this with an AI photo recognition platform, their own VM tool, and an impressive Isolation Mode that can sever the system at the click of a button from remote access, 3rd-party PHP, and any external requests (necessitating a restart to disable). However, as this brand is a Chinese brand, there will always be question marks raised by users about how this system compares with Taiwanese-based systems. This is a little unfair, given that Terramaster, Asustor, and QNAP were all successfully hit by the same ransomware attack (Deadbolt) a few years back, so there was plenty of ‘vulnerability’ to spread around!

In terms of hardware, Terramaster has been making some impressive and aggressive strides in this area—with the recent launch of their 3-part F4-424 Intel NAS series (Standard, Pro, and MAX), the release of two 8-bay M.2 NVMe 10GbE equipped systems (the F8 PLUS and F8 SSD PLUS), and new desktop and rackmounts hot on their heels. They have also scaled up the design to better improve cooling, efficiency, and just general visual appeal.

Value Series	Best All Rounder	Prosumer NAS
F2-424 2-Bay NAS	F4-424 Max 4-Bay NAS	T9-500 Pro 9-Bay NAS
$369 on Amazon (Check Here)	$819 on Amazon (Check Here)	$1499 on Amazon (Check Here)

However, much like Asustor, their software is just not able to challenge the standard that Synology has set. For buyers looking for smooth and easy utilization like Synology, Terramaster’s TOS has the danger of feeling a little clunky. Their latest release, TOS6, brings new features, software standards, and design to the mix, but it lacks the range of mobile applications, desktop client tools, and consistent UX/presentation that Synology seems to do so well. Terramaster is a fantastic value-for-money choice, and I would argue they have significantly scaled up the level of hardware and software utility they provide year on year. But they still have a way to go before they can hit the same notes as Synology DSM yet.

WD / Netgear vs Synology?

This is a pretty short one! The answer is no! Both WD and Netgear have regularly reduced their hardware ranges and the frequency of software updates these last few years, and although there are a decent range of business file server systems still being released, the general home/enthusiast/prosumer level of hardware is pretty poor and uninteresting compared to everyone else on this list so far. I cannot help but get the feeling that, aside from some basic backup NAS systems that are still listed at the majority of retailers, the bulk of their range has been in circulation for 5-6 years now without any refresh in sight. For basic target file/folder storage, these systems still provide some limited modern NAS utility, but overall, they are a fairly weak alternative to Synology’s offerings in 2025.

A UniFi NAS?

With increased mentions and leaks online towards a potential NAS in the works from UniFi, this could be a very credible alternative to Synology in terms of software UX and presentation. UniFi, and its incredibly user-friendly UX featured on their Switch, Router, NVR, and Dream Machine combination systems, is where UniFi shines. No doubt any UniFi NAS solution would need to similarly blend into their ecosystem to the same degree. That said, if they were to launch a system, all their experience in the fields of network management, router security, and surveillance systems might not necessarily translate into a similar pedigree in network-attached storage. It’s hard to discuss how or if UniFi could fill any market space that a potential Synology absence would create, as they do not have any systems out in the market to make an informed decision. This is for the “To Be Continued…” pile!

Drobo vs Synology?

No…just…no. See Video Below:

IceWhale / ZimaCube

This is a very interesting one. 2023 and 2024 saw several companies arrive in the turnkey NAS space via the crowdfunding route (we already discussed UGREEN as the biggest example), wanting to break into the market. However, IceWhale benefits from having already launched two previous successfully fulfilled campaigns and is just completing their third one with the ZimaCube NAS system. Arriving with the lightweight containerized platform Zima OS (a modified version of their existing Casa OS), this new series is pretty impressive for its scale and price point at launch. Add to that the significantly unique design, impressive use of 10GbE and Thunderbolt over IP, and a 6x HDD / 4x NVMe system in a compact case, and you can see why they have made a fairly significant splash for a brand that is comparatively unheard of compared to Synology, QNAP, etc.

However, as robust as their range of solutions is (ZimaBoard, ZimaBlade, and ZimaCube), the software is still very rudimentary compared to the bulk of other browser GUI and more “operating system”-stylized UX. There are virtually no client applications, except for their own system search and connection client tools. An eventual successor to Synology, if they moved upwards toward bigger and more business-oriented solutions, would need to hit the software functionality and user experience exceedingly early and exceedingly well.

Mini PC Brands – Lincplus, Aoostar, etc.

This is an odd one. There have been a large number of solutions appearing on sites such as AliExpress that arrive as “OS-Free” services, allowing a user to get a pre-built NAS hardware solution (i.e., no need to build one yourself, which takes longer and requires a degree of technical understanding). The end user can then choose to install popular and well-established solutions like TrueNAS, UnRAID, OpenMediaVault, and more.

Value Option	Best All Rounder	SSD Focused NAS
Aoostar WTR Pro 4-Bay NAS	Minsiforum MS-01 3/6-Bay NAS	Lincplus Lincstation N1 6-Bay NAS
$399-799 on Amazon (Check Here)	$399 on Amazon (Check Here)	$399 on Amazon (Check Here)

This serves as an impressively economical solution and has significantly grown in popularity in 2023/2024, but these 3rd-party software platforms lack a lot of the ease of use and quality of life client tools for modern devices that Synology features. Indeed, despite efforts like UnRAID 7 making its day-to-day use much easier, and TrueNAS working with HexOS for a more user-friendly output, these still pale in comparison to DSM and will also require a greater degree of technical user input in the long term to maintain stability, versus Synology’s rather more “it takes care of itself” design.

Synology vs EVERYONE ELSE – Conclusion and Verdict

If Synology were to leave the home/enthusiast/prosumer/small business tier very soon, I do think QNAP would stand to reoccupy this ground. However, give it 2-3 years, and I do think players like Terramaster, Asustor, and yes—even UGREEN—are poised to give QNAP some serious consumer competition. No doubt Synology is still keeping an eye on their competition (big and small) and would not willingly or easily give up this sector without a fight. However, there is no denying that the turnkey NAS industry is no longer the 2-3 horse race it was just five years ago!

Synology VS Terramaster NAS Drives in 2025 – Which One Deserves Your Data?

Synology and TerraMaster are two well-established brands in the network-attached storage (NAS) industry, each targeting a range of users from home enthusiasts to small and medium-sized businesses. Synology, a Taiwanese company with over two decades in the field, is widely recognized for its DSM (DiskStation Manager) software, which emphasizes stability, security, and integration within a tightly controlled ecosystem. TerraMaster, while newer to the market, has steadily gained ground by offering hardware-focused, cost-effective solutions with increasing software support via its TOS (TerraMaster Operating System) platform.

I want to provide a side-by-side comparison between Synology and TerraMaster as they stand in 2025, focusing on the real-world differences in hardware, storage, software, and security. The goal is to outline the practical strengths and weaknesses of each brand without leaning heavily toward subjective preferences or historical bias. This is especially relevant for users reevaluating Synology due to recent policy shifts, or for those considering TerraMaster as a flexible and affordable alternative.

When evaluating Synology’s hardware catalog, the company demonstrates a clear strategy of segmenting performance tiers through tightly integrated systems. The FS (FlashStation) series targets ultra-low latency workloads with powerful multi-core CPUs and all-flash designs. For instance, the FS6400 and FS3600 offer 240,000 and 195,000+ 4K random write IOPS respectively, built for high-throughput environments. The HD series goes a different direction, pushing density with up to 300 drives in models like the HD6500, which pair with dual 10-core CPUs and provide over 6,600 MB/s throughput. Meanwhile, the SA and XS/XS+ series address scalable performance and redundancy needs, offering dual-controller setups, high RAM ceilings, and optional Fibre Channel or 25/40GbE expansion. Synology’s Plus and Value series provide consumer-grade flexibility, but these are becoming increasingly closed ecosystems with limited hardware compatibility and optional expansion cards restricted to specific interfaces or models.

TerraMaster, in contrast, focuses its value proposition heavily on maximizing hardware capabilities per dollar. Even in their midrange, systems like the F6-424 Max or F4-424 Pro include Intel Celeron or i3 CPUs, 2.5GbE or 10GbE connectivity, NVMe SSD support, and upgradeable RAM—all within sub-$700 price ranges. Larger units like the T12-500 Pro or U24-722-2224 scale storage up to 24 bays or beyond, while still offering competitive CPUs and abundant connectivity options. TerraMaster also maintains a vast lineup of hybrid RAID-capable DAS and NAS systems, including USB 3.2 Gen 2 enclosures for fast, direct-attached storage. Unlike Synology, TerraMaster maintains open compatibility with third-party drives and offers more consistent support for M.2 NVMe storage expansion, SSD caching, and even integrated GPU support in some models.

 TerraMaster’s TOS (TerraMaster Operating System), currently in version 5.1 with version 6 available on select systems, has seen rapid growth in capabilities and usability over the last few years. While it doesn’t yet match DSM’s polish, it has made significant strides in offering equivalent functionality. TOS supports Btrfs-based snapshots, Rsync and CloudSync for cloud backup, Docker container deployment, and VirtualBox-based virtualization. While the latter is less tightly integrated than Synology’s VMM, it does allow for third-party VM deployment in a usable way.

TerraMaster has also developed TerraSync, a synchronization tool designed to rival Synology Drive, and supports both media management and AI-enhanced photo sorting with apps like Terra Photos. However, many of TOS’s functions rely more heavily on community-driven or open-source third-party applications, resulting in a slightly less unified experience overall.

In terms of application ecosystems, Synology’s App Center clearly offers the broader and deeper catalog, particularly for business users. First-party applications such as Synology Office, Chat, MailPlus, and Note Station deliver a productivity-focused alternative to cloud services, and their Surveillance Station software stands out as one of the most powerful NVR platforms in the NAS market.

TerraMaster’s App Center includes essential tools but lacks the same level of first-party development. However, it makes up for this in openness: TerraMaster supports a wide array of third-party and open-source platforms more freely, including Jellyfin and Unraid. Moreover, TerraMaster allows alternative operating systems like TrueNAS to be installed without voiding the warranty, which adds considerable flexibility for tech-savvy users. Overall, Synology delivers a more unified and polished software experience, while TerraMaster emphasizes adaptability, freedom, and cost

Synology vs Terramaster NAS – Security and Safety

Synology has long maintained a strong reputation in the NAS sector for prioritizing system security, and this is evident in how thoroughly security is integrated throughout DSM. Synology’s Security Advisor provides active scanning for vulnerabilities, misconfigurations, and password weaknesses, while its firewall, account protection, and IP auto-blocking features offer practical layers of defense against unauthorized access. Synology also supports comprehensive SSL certificate management via Let’s Encrypt and offers two-factor authentication (2FA) with TOTP and hardware key support. From a business continuity perspective, DSM includes native WORM (Write Once Read Many) capabilities and encrypted shared folders to protect sensitive data from tampering or deletion. Perhaps most critically, Synology operates a dedicated PSIRT (Product Security Incident Response Team), frequently publishes security advisories, and participates in high-profile vulnerability testing events like Pwn2Own—demonstrating a serious commitment to vulnerability discovery and remediation.

TerraMaster’s security offering has become more robust over recent years, particularly with the development of Isolation Mode—a unique feature allowing users to instantly sever all external access and remote services with a single click. This acts as a kill switch in the event of a suspected breach or malware event. TOS also includes a system-level security scanner that checks for basic vulnerabilities and enables 2FA, SSH restrictions, and SSL certificate deployment. While TerraMaster’s platform does not offer as many granular policy tools as DSM, it supports core protocols like OpenVPN and L2TP for secure remote access and regularly issues firmware updates in response to new threats. The company also now provides greater transparency regarding CVEs (Common Vulnerabilities and Exposures), though its advisory frequency and scope remain smaller than Synology’s.

Security Feature	Synology DSM	TerraMaster TOS	Notes
System Hardening	Proactive hardening (limited root access, secure defaults)	Moderately hardened; more configurable access	Synology limits risky configurations by design
Security Scanner	Built-in DSM Security Advisor with customizable scan depth	TOS Security Center (less detailed on TOS 5.x)	Synology provides more actionable alerts
2FA Support	TOTP-based (authenticator apps, email)	TOTP-based	Parity on two-factor authentication
SSL Certificate Support	Native Let’s Encrypt + custom certs via GUI	Let’s Encrypt + custom certs via GUI	Equal support, easy HTTPS setup
Firewall Management	GUI-based port/IP firewall with profiles	Firewall settings available (less granular)	Synology allows more granular firewall policy creation
Isolation Mode / Kill Switch	Not available	Isolation Mode disables all external access with one click	Advantage: TerraMaster for emergency lockdowns
Vulnerability Response (PSIRT)	Dedicated PSIRT, public advisories updated monthly	Less frequent disclosure, fewer details published	Synology actively discloses and patches
Security Bug Bounty Program	Yes – active white-hat reward program	No public bounty program known	Synology engages with global researchers
Third-Party App Restrictions	Limited for security; sandboxed services	More open but requires user discretion	Synology prioritizes closed ecosystem safety
Remote Access Protection	QuickConnect includes traffic relay + DDNS + 2FA	TNAS.online DDNS with isolation toggle	Both offer encrypted remote access, but Synology uses multiple layers
Malware Detection	Real-time malware scanner, browser warnings	Included scanner, but simpler in scope	DSM scanner is more active and integrated
Backup Verification	Integrity verification in Active Backup	TerraSync + cloud/USB support (manual checks)	DSM offers automated backup health reports
Surveillance Hardening	Encrypted video storage + HTTPS + IP blocklist	Surveillance App with HTTPS, still evolving	Synology Surveillance Station is more mature and secure
Ransomware History	2014 “SynoLocker” (quickly patched)	2021–22 “Deadbolt” attacks (multiple waves)	TerraMaster more affected in recent years
Update Frequency	Frequent monthly patches	Less frequent, varies by model	DSM has a consistent schedule and transparency

Despite these advancements, TerraMaster’s security record has faced scrutiny in the past due to incidents like the Deadbolt ransomware attacks. These incidents, which also affected other NAS vendors, prompted significant user backlash and a push for more proactive security updates and faster patching. TerraMaster has since responded by improving software integrity and introducing layered protection features, but the lingering perception remains that Synology maintains a stronger and more proactive security posture overall.

This perception is reinforced by Synology’s investment in ongoing vulnerability research, bug bounty programs, and a broader portfolio of security-focused tools. As it stands in 2025, Synology continues to lead in NAS security maturity, while TerraMaster has made meaningful progress—especially with unique features like Isolation Mode—but still has ground to cover in enterprise-level protections and threat response.

Synology vs Terramaster NAS – Conclusion and Verdict

Comparing Synology and TerraMaster in 2025 ultimately highlights a clear philosophical divide between the two NAS brands. Synology continues to build upon a long-standing focus on refined software, tight integration, and enterprise-grade security. Its DSM platform remains one of the most polished and feature-rich operating systems in the NAS space, offering a wide selection of first-party tools for backup, surveillance, virtualization, and secure access. However, this ecosystem is increasingly closed, with stricter hardware compatibility requirements and limited support for third-party drives, SSDs, and expansions. For users who prioritize reliability, ease of use, and support from a mature software ecosystem, Synology remains a compelling—if sometimes restrictive—option.

TerraMaster, by contrast, leans into flexibility and hardware value. Its broad portfolio includes NAS units ranging from entry-level to high-performance multi-bay SSD systems, often at lower price points than Synology’s equivalents. TOS 5.1 and the newer TOS 6 have brought meaningful improvements in UI and functionality, while still maintaining a more open approach to compatibility and user customization. Features like native Jellyfin support, VirtualBox VM deployment, and the ability to install TrueNAS or Unraid without voiding warranty make TerraMaster a standout for DIY-leaning users or those with niche requirements. However, its software, while improving, does not yet match the polish or depth of Synology DSM, especially in areas like virtualization, surveillance, and enterprise security.

In the end, choosing between Synology and TerraMaster depends heavily on user needs and expectations. Synology suits users who want a highly stable, all-in-one solution with minimal configuration and long-term support. TerraMaster offers greater adaptability and value for power users who are comfortable managing third-party apps and want to stretch their hardware investment further. Neither approach is inherently better—each has its strengths and trade-offs. Buyers seeking a tightly controlled, secure environment may gravitate toward Synology, while those who value hardware scalability, open software choices, and affordability may find more freedom with TerraMaster.
