Terramaster D4 SSD Review -Design and Storage

The Terramaster D4 SSD adopts a compact and minimalist design that prioritises space efficiency while accommodating high-performance M.2 NVMe storage. The chassis is constructed with a combination of metal and reinforced plastic to balance durability with weight reduction, making it practical for desktop setups or mobile editing stations. Measuring 138mm in height, 60mm in width, and 140mm in depth, it has a footprint smaller than many portable RAID enclosures yet houses four internal M.2 2280 slots. Ventilation is a key part of the design, with perforations along the chassis and an internal airflow path from the bottom intake to the top exhaust. This airflow design is paired with a smart dual-fan system to keep temperatures stable under sustained workloads. The minimalist exterior is free of unnecessary styling, focusing instead on functionality and discrete operation in professional environments.

Internally, the storage layout is based entirely on NVMe architecture, with each of the four bays supporting PCIe Gen4 x1 bandwidth allocation. This ensures each SSD has dedicated lane access to maintain predictable throughput, rather than sharing limited controller bandwidth as seen in some lower-cost enclosures. The D4 SSD supports up to 8TB per drive, giving a maximum raw capacity of 32TB, though higher capacities may be supported as larger consumer and enterprise NVMe drives are verified. This design choice prioritises performance consistency and reduces the risk of bottlenecks, particularly when drives are accessed simultaneously for large file transfers or multi-stream media editing.

The enclosure is not equipped with a hardware RAID controller, meaning all drives operate in independent single-disk mode by default. Users wishing to configure RAID 0, 1, or other levels must do so using their operating system’s built-in storage management tools or third-party RAID software. This approach reduces internal complexity, lowers power draw, and avoids thermal buildup from additional processing hardware, but shifts configuration responsibility to the user. For some workflows, particularly those involving high-performance NVMe SSDs, host-managed RAID can still deliver substantial speed gains without affecting compatibility.

For cooling, the D4 SSD uses an active design with two 50mm temperature-controlled fans. These are managed by four onboard temperature sensors, adjusting fan speeds based on workload and heat generation. The airflow design is optimised to pass directly over the NVMe modules and the mainboard’s heat-generating components. While the unit does not include NVMe heatsinks by default, there is space to install aftermarket options if desired. Terramaster’s decision not to bundle heatsinks reflects a balance between cost and compatibility, as different SSDs have varying thermal needs, and some users may prefer specific heatsink designs.

From a noise and usability standpoint, the D4 SSD is intended to operate unobtrusively in environments such as home offices, studios, and editing suites. In standby mode with SSDs installed, the noise level is measured at 19dB(A), making it quieter than many desktop PCs and suitable for near-silent workspaces. Combined with its small physical footprint, this makes it a storage device that can be positioned close to the user without being a distraction, even under full load during extended transfers or media rendering sessions.

Terramaster D4 SSD Review – Internal Hardware

Inside the Terramaster D4 SSD, the hardware is built around a dedicated USB4 bridge controller, the ASMedia ASM2464PDX, which is designed to maintain high throughput across multiple NVMe drives without the lane bottleneck issues found in some lower-cost enclosures. Each M.2 slot is wired for PCIe Gen4 x1 bandwidth, providing up to 2,000MB/s potential per drive, which is then aggregated and managed through the USB4 interface.

This design ensures predictable scaling in both single-drive and multi-drive use, with performance closely tied to the host system’s RAID or file management configuration. The PCB is perforated in multiple areas to enhance passive airflow in conjunction with the active cooling fans, helping to maintain SSD performance during sustained workloads such as large file transfers or continuous video editing.

The storage slots themselves support PCIe NVMe M.2 2280 SSDs, making the D4 SSD compatible with a wide range of consumer and professional-grade drives. While the official capacity limit is listed as 8TB per drive, the enclosure is not restricted by proprietary firmware, allowing for potential support of larger modules as they become available. The absence of hardware RAID keeps internal processing simple, reducing latency and power draw, while allowing the enclosure to work equally well in macOS, Windows, and certain NAS expansion scenarios where the RAID logic is handled externally. Additionally, the enclosure supports multiple file systems including NTFS, APFS, exFAT, FAT32, and EXT4, depending on the host environment.

Power delivery to the enclosure is handled through a 24W external adapter, with a wide input voltage range of 12V to 20V for compatibility with common laptop and mini-PC power supplies. This not only makes it more versatile for travel or integration into mobile production setups but also reduces the need for proprietary adapters.

The included USB4 Type-C cable is 0.8m in length and rated for up to 80Gbps, significantly higher than the device’s 40Gbps requirement, ensuring minimal signal degradation over time. Thermal and power management are monitored by four internal sensors, which regulate the fan speeds to balance cooling and noise.

Terramaster D4 SSD Review – Connectivity

The Terramaster D4 SSD keeps its external connectivity simple, focusing on delivering the highest possible throughput over a single interface. The primary connection is a USB4 Type-C port located on the rear of the unit, providing up to 40Gbps of bandwidth when used with a compatible host device. This interface also ensures backward compatibility with Thunderbolt 3, Thunderbolt 4, Thunderbolt 5, and USB 3.x standards, although maximum speeds will vary depending on the protocol supported by the connected system. This approach makes the D4 SSD suitable for a wide range of setups, from modern Mac computers and high-end Windows workstations to certain NAS devices that offer USB4 or Thunderbolt connectivity for expansion.

The unit does not draw power from the USB4 connection, which is essential given the requirements of running four NVMe drives under load. This separation ensures stable power delivery regardless of the workload, preventing thermal throttling or performance drops caused by insufficient bus power.

The only other physical interface elements are the cooling ventilation openings, the power button, and status indicators. The ventilation is positioned to support the enclosure’s top-to-bottom airflow, with exhaust positioned to avoid heat recirculation. The power button is recessed to prevent accidental shutdowns, and the indicator lights provide a quick visual status of drive activity. While the D4 SSD avoids additional ports such as USB hubs or SD card readers, this streamlined design prioritises stability and speed for storage operations, aligning with its role as a dedicated high-bandwidth storage enclosure rather than a multifunction docking station.

Terramaster D4 SSD Review – Performance and Tests

In practical testing, the Terramaster D4 SSD demonstrated performance levels consistent with the capabilities of its USB4 interface and internal PCIe lane allocation. When fitted with a single PCIe Gen4 NVMe SSD and connected to a compatible Windows host system, sequential transfer rates reached around 1,480MB/s for reads and 1,140MB/s for writes in CrystalDiskMark, with mixed 70/30 read/write workloads averaging 1,286MB/s.

AJA System Test results with a repeated 1GB file showed roughly 1,400MB/s read and 1,300MB/s write, while ATTO Disk Benchmark recorded peaks of 1.57GB/s read and up to 1.5GB/s write.

These results represent roughly three-quarters of the theoretical maximum per-lane Gen4 x1 performance, with minor variations attributable to SSD model and host configuration.

With four SSDs installed and configured in RAID 0 via Windows Disk Management, throughput scaled significantly.

In AJA testing, read speeds reached 2,500MB/s and writes 2,300MB/s. CrystalDiskMark produced 2,047MB/s reads and 1,927MB/s writes in sequential tests, with mixed workloads at around 1,799MB/s.

ATTO testing peaked at approximately 2.93GB/s read and 2.66GB/s write. These figures are below the absolute maximum possible for USB4 but remain strong for a host-managed RAID array without dedicated hardware acceleration.

The results indicate that with a more capable RAID implementation, sustained speeds above 3GB/s would be achievable, making the D4 SSD suitable for high-bandwidth applications such as multi-stream 4K or 6K video editing. Thermal performance was another key testing area given the high-speed NVMe drives involved. Under sustained load with all four SSDs active, the enclosure’s dual-fan cooling system maintained stable operating temperatures without noticeable thermal throttling. Noise output, even at maximum fan speed, remained low enough for close-proximity use in an editing suite or home office. The absence of included NVMe heatsinks did not lead to significant overheating in tests, though installing aftermarket heatsinks could be beneficial for prolonged heavy workloads or in warmer environments.

Power consumption measurements showed efficient operation relative to its performance. With all drives in hibernation, draw was close to 1W; in standby, it was 3–4W; and at full load, the system used only 5–6W. This efficiency, combined with the wide voltage input support, makes the D4 SSD practical for mobile production setups and continuous desktop use without significant power overhead. Compatibility was confirmed across both macOS and Windows systems, with macOS tests achieving up to 3,257MB/s reads and 3,192MB/s writes using four Samsung 990 PRO 4TB SSDs in RAID 0 on a Mac mini with an Apple M4 chip.

Test Setup / Condition Read Speed (MB/s) Write Speed (MB/s)
1x PCIe Gen4 NVMe SSD (AJA, 1GB test) ~1,400 ~1,300

Standby Power Draw 3–4W
Full Load Power Draw 5–6W

Terramaster D4 SSD Review – Verdict and Conclusion

The Terramaster D4 SSD positions itself as a compact, high-speed, and flexible all-flash enclosure for users who require consistent bandwidth and expandable capacity over USB4. Its PCIe Gen4 x1 lane allocation per drive, paired with the ASMedia ASM2464PDX controller, ensures that performance scales predictably from single-drive use to fully populated configurations without the bottlenecks common in lower-end enclosures that multiplex lanes. While the absence of built-in hardware RAID will be seen as a limitation for users wanting an all-in-one solution, the decision to leave RAID management to the host system helps keep the enclosure’s design simpler, power consumption lower, and thermal output under better control. This host-managed approach also allows greater flexibility in choosing software RAID solutions optimised for specific workflows, whether for performance (RAID 0), redundancy (RAID 1), or other advanced configurations. Combined with its small footprint, professional-grade cooling, and wide voltage input range, the D4 SSD fits naturally into both fixed and mobile setups where reliable sustained throughput is essential.

From a value and application standpoint, the D4 SSD’s test results put it among the faster multi-bay USB4 NVMe enclosures currently available, especially given its ability to sustain multi-gigabyte transfers under prolonged load without thermal throttling. It is particularly well-suited to professionals in media production, post-processing, and high-resolution video editing who need large, portable, and quiet storage capable of handling multiple uncompressed video streams in real time. The unit’s quiet operation, even when all drives are active, makes it practical for use in audio-sensitive environments, and its compatibility with Thunderbolt 3, 4, and 5 as well as USB 3.x protocols expands its usability across a wide variety of systems. Potential buyers should, however, factor in the additional cost of populating all four slots with high-capacity NVMe SSDs and consider adding aftermarket heatsinks for continuous heavy workloads, as none are included. For those who already operate in environments where RAID is managed externally or within the operating system, the D4 SSD represents a balanced combination of speed, efficiency, and build quality that should appeal to both Windows and macOS professionals seeking long-term, high-performance storage expansion.

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.

Terramaster D1 SSD Review – Design and Storage

The D1 SSD Plus adopts a minimalist, industrial-style design built entirely from aluminium alloy, providing both structural durability and efficient passive heat dissipation. Its solid unibody construction not only makes the device more resistant to daily wear but also allows for a larger heat-spreading surface compared to typical plastic or hybrid enclosures. Measuring just over 11 cm in length, it remains small enough for mobile use while retaining the thermal mass needed to handle sustained high-speed transfers without performance throttling. The matte finish helps reduce the appearance of fingerprints and scratches, making it better suited to frequent handling in professional environments.

Internally, the unit supports a single M.2 2280 PCIe NVMe SSD, accommodating capacities of up to 8TB in a single slot. The choice to limit support to NVMe, rather than SATA-based M.2 drives, ensures the interface is not a bottleneck to the USB4 connection. The enclosure uses a PCIe Gen 4×4 lane allocation, meaning that while it can achieve impressive transfer speeds, installing a Gen 3 drive will limit throughput to roughly half the rated maximum. This makes SSD selection critical for users seeking top performance, especially in workflows involving large sequential file transfers or high-speed scratch disk usage.

The passive cooling system is one of the more notable aspects of the D1 SSD Plus’s design. Instead of an active fan, the aluminium chassis itself acts as a heatsink, with thermal pads positioned to draw heat away from the SSD and controller. During testing with repeated large file transfers, drive temperatures peaked at around 44–45°C, and the enclosure exterior measured approximately 41–42°C, remaining well below thermal throttling thresholds. This approach eliminates moving parts, improving reliability and making the device completely silent, a benefit for audio-sensitive production environments.

From a portability perspective, the D1 SSD Plus is supplied with a compact 0.3m USB4 Type-C cable and a soft carry bag for transport. The short cable supports 40Gbps data rates and up to 240W power delivery, though its length may be restrictive for certain setups, such as when connecting to desktop systems positioned under a desk. Weighing just 246grams without a drive, it is light enough to be carried daily yet solid enough to feel substantial in use.

In terms of safety and operational protection, TerraMaster has included components to guard against short circuits, power surges, and electrostatic discharge. These measures, combined with the robust chassis, aim to keep the enclosure operational even in less controlled environments such as on-location shoots or travel-based editing sessions. For storage expansion scenarios, it can act as either a primary drive for active projects or a fast external repository for completed work, depending on the installed SSD’s performance and endurance characteristics.

Terramaster D1 SSD Review – Internal Design

Inside the D1 SSD Plus, the primary component enabling its performance is the ASMedia ASM2464PDX controller. This USB4-to-PCIe bridge is widely used in high-speed external enclosures, offering stable throughput and supporting PCIe Gen 4×4 lane allocation to the installed SSD. TerraMaster is unusually transparent in publicly listing the controller model and lane configuration, information that many manufacturers omit. This clarity helps users understand the real-world performance limits and the importance of pairing the enclosure with a compatible SSD to reach the quoted speeds.

The M.2 slot supports the 2280 form factor exclusively and is physically keyed for NVMe drives, preventing the installation of incompatible SATA models. Internally, thermal pads are pre-positioned to ensure consistent contact between the SSD and the aluminium housing, which doubles as a heatsink. This direct contact method maximises heat transfer efficiency, enabling the enclosure to sustain high-speed operation without thermal throttling. The lack of an active fan reduces power draw and potential mechanical failure points, aligning the product with professional needs for quiet and reliable operation.

The enclosure draws power entirely from its USB4 connection, operating at 5V and consuming up to 7.5W during active read/write workloads. In idle or hibernation mode, this drops to around 5.5W. The absence of a dedicated power supply simplifies setup and enhances portability, though it also means that connection stability is dependent on the host device’s USB port quality and adherence to USB4 or Thunderbolt specifications. This bus-powered approach makes the D1 SSD Plus practical for mobile workstations, ultrabooks, and modern desktops without spare power connections.

Component / Feature Detail
Controller ASMedia ASM2464PDX (USB4 to PCIe Gen 4×4 bridge)
Supported SSD Types PCIe NVMe M.2 2280 only
Maximum Supported Capacity 8TB (single drive)
Lane Allocation PCIe Gen 4×4
Cooling System Passive aluminium heatsink with thermal pad contact
Power Source Bus-powered via USB4 (5V)
Power Consumption 7.5W active, 5.5W hibernation
Thermal Management Peak SSD temp ~45°C, enclosure ~42°C under sustained load

Terramaster D1 SSD Review – Connection and Bandwidth

The D1 SSD Plus features a single USB Type-C port located at the rear of the enclosure, serving as its sole data and power interface. This port supports USB4 at 40Gbps, ensuring maximum compatibility with modern high-speed standards while maintaining backward support for Thunderbolt 5/4/3 and USB 3.x generations. This allows the enclosure to integrate into a range of environments, from the latest Apple Silicon systems to older Windows workstations. However, TerraMaster notes that certain Thunderbolt 3-equipped Windows PCs may lack complete USB4 protocol support, which can prevent the device from being recognised unless connected to a different port.

The included 0.3m USB4 cable is rated for the full 40Gbps bandwidth and supports up to 240W of power delivery, even though the enclosure itself draws only a fraction of that power. Its short length makes it well-suited for portable laptop-based workflows but less ideal for desktop systems that require longer reach. Users seeking more flexibility may need to source a third-party cable with equivalent specifications to maintain the enclosure’s full performance potential.

Given the high-speed nature of USB4, signal integrity is critical. The D1 SSD Plus uses a reinforced internal connector to reduce wear and maintain a stable connection over repeated cable insertions. Combined with the aluminium body’s shielding properties, this helps minimise data errors and interference, which is particularly relevant when transferring large multimedia files or working directly from the drive in editing software.

Terramaster D1 SSD Review – Tests

In synthetic benchmarks, the D1 SSD Plus achieved results close to its advertised maximums when paired with a high-quality PCIe Gen 4×4 SSD. Using an AJA 1GB test file loop, sustained read speeds were observed between 3,000 and 3,100MB/s, with writes maintaining 2,550 to 2,600MB/s.

Peak measurements during testing reached 3.55GB/s for reads and 2.8GB/s for writes, confirming that the enclosure can deliver high throughput consistently without early throttling. Mixed workload tests, such as a 70/30 read/write access pattern, still sustained around 2,500MB/s, indicating balanced performance even under varied data operations.

CrystalDiskMark results mirrored the AJA findings, with sequential read speeds consistently exceeding 3,000MB/s and writes holding near 2,600MB/s in repeated trials. These figures place the D1 SSD Plus among the faster single-bay USB4 enclosures currently available, particularly in its ability to sustain speeds over prolonged activity. The stability here is largely attributed to the passive aluminium cooling, which prevented temperature-induced drops in transfer rates that are common in less thermally capable designs.

Real-world file transfers also reflected strong performance. A 100GB mixed-content dataset consisting of video clips, high-resolution images, PDFs, and documents transferred in 63 seconds, averaging 1.58GB/s over the duration. While this figure is lower than synthetic benchmark peaks, it remains well above the speeds of typical USB 3.2 enclosures, providing tangible time savings for users moving large batches of files. The ability to maintain high sustained write speeds is particularly beneficial for workflows such as direct-to-disk recording or continuous large dataset backups.

Temperature monitoring during performance testing showed the installed SSD peaking at 44–45°C after over five minutes of sustained large file writes, with the enclosure’s exterior registering around 41–42°C. These results suggest that the cooling system is sufficient to handle extended workloads without user intervention, making the D1 SSD Plus a viable option for scenarios where the drive may be used heavily for prolonged periods, such as editing directly from the external storage.

Test Type Read Speed (MB/s) Write Speed (MB/s) Notes
AJA 1GB loop 3,000–3,100 2,550–2,600 Sustained, no throttling
AJA peak 3,550 2,800 Short bursts
CrystalDiskMark sequential ~3,089 ~2,600 Consistent across multiple runs
Mixed workload (70/30 R/W) ~2,500 ~2,500 Balanced read/write workload
100GB real-world transfer Avg. 1,580 N/A Completed in 63 seconds
Peak SSD temperature N/A N/A 44–45°C (enclosure 41–42°C) during sustained use

Terramaster D1 SSD Review – Verdict and Conclusion

The TerraMaster D1 SSD Plus positions itself as a high-speed, bus-powered USB4 enclosure that places equal emphasis on sustained performance, heat management, and compatibility across multiple connection standards. Its integration of the ASMedia ASM2464PDX controller with a PCIe Gen 4×4 lane configuration ensures that it can fully utilise the available 40Gbps bandwidth when paired with a suitable SSD, avoiding the thermal throttling that can undermine performance in less capable enclosures. TerraMaster’s decision to openly publish controller details, lane allocation, and maximum tested speeds gives technically minded buyers more confidence in what the enclosure can achieve, and helps explain why it maintained stability during repeated multi-gigabyte transfer tests in your review. The combination of a compact footprint, aluminium passive cooling, and complete silence during operation makes it suitable not only for static desktop setups but also for field work, where portability and reliability matter. With support for capacities up to 8TB and a choice of file systems including NTFS, exFAT, APFS, and EXT4, it can be easily integrated into both macOS and Windows workflows without major reconfiguration.

There are, however, practical considerations for prospective buyers. The included 0.3m USB4 cable, while capable of full 40Gbps data rates and 240W power delivery, is short enough to be inconvenient for tower PC users or multi-device workstations, and replacing it with a certified high-speed cable may be necessary in such environments. Furthermore, although the enclosure can accept any PCIe NVMe M.2 2280 SSD, achieving top-tier performance depends on selecting a PCIe Gen 4×4 drive, as using Gen 3 or slower-lane SSDs can halve the potential throughput. Your review also highlighted that while TerraMaster frequently notes the importance of Gen 4 drives, they do not provide detailed compatibility charts or recommend specific models, which could help less experienced buyers avoid suboptimal results. In practice, the D1 SSD Plus delivers a combination of sustained speed, thermal efficiency, and solid build quality that positions it as a strong choice for video editors, media professionals, and advanced home users who require portable storage without sacrificing reliability or performance.

Running OpenAI gpt-oss-20b and gpt‑oss-120b in AWS on your own EC2 instance

18 août 2025 à 18:17
OpenAI recently released its first open-weight models, gpt-oss-20b and gpt‑oss-120b, which you can download and run with Ollama. If security and privacy are essential when using AI models, you might not want to use the vendor's chat UI or API. The most powerful AI models require significant computing power and memory, and many desktop devices cannot run these models. Although Ollama was not designed with remote connections in mind, it is still possible. In this series, I will explain how to install OpenAI's open-weight models using Ollama and connect to them remotely from various applications, including VS Code GitHub Copilot. In this first post, I will outline how to choose the right size for your virtual machine, using EC2 instance types in AWS as an example.

The UGREEN DH4300 PLUS NAS Review – Good Value?

The UGREEN DH4300 Plus is a 4-bay NAS solution introduced quietly into the company’s growing lineup of storage devices, appearing online without the usual fanfare. Closely related to the DH4300 Plus in both hardware and feature set, this model forms part of UGREEN’s value-tier NAS systems, designed to provide essential private cloud functionality at a lower cost. Targeted at home users, prosumers, and small offices, the DH4300 Plus offers a mix of modern storage capacity and lightweight computing through its ARM-based architecture. With support for RAID 0, 1, 5, 6, and 10, 2.5GbE networking, and up to 120TB of raw storage across four SATA bays, the device aims to provide a reasonably capable platform for tasks like file serving, multimedia streaming, and basic photo management.

However, the DH4300 Plus doesn’t just follow the pattern of other budget NAS solutions. It includes features uncommon at this price point, such as HDMI output and 10Gbps USB connectivity, which extend its use case beyond simple backups into media and even light-duty AI-powered photo organization. Its system-on-chip, the Rockchip RK3588, is more powerful than the processors seen in comparable entry-level NAS systems from other brands like Synology or QNAP. While it lacks the high-end features of premium NAS units—such as multi-port networking or M.2 expansion—it still manages to deliver a compact, energy-efficient package suited to most daily NAS workloads. This review breaks down each component of the DH4300 Plus, from its physical design and internal hardware to its software ecosystem, to help users decide whether this is the right solution for their needs.

UGREEN DH4300 NAS Review – Quick Conclusion

The UGREEN DH4300 Plus stands out as a well-equipped entry-level NAS that offers considerably more than its modest price tag suggests, positioning itself as a serious contender in the growing value NAS market. Powered by the RK3588 ARM processor and backed by 8GB of LPDDR4X memory, it delivers capable performance for a wide range of NAS tasks including file sharing, media streaming, light containerization via Docker, and AI-assisted photo management. Its support for 2.5GbE networking, 10Gbps USB ports, and HDMI 2.1 output adds versatility, enabling faster-than-Gigabit transfer speeds and options for direct media playback or on-site display access. The system’s low power consumption, compact footprint, and quiet operation make it especially well-suited for 24/7 deployment in home or small office environments. AI functionality for face recognition and album generation, powered by the on-chip NPU, further enhances its value for users managing large personal photo or media libraries. However, the device is limited by its lack of PCIe or M.2 expansion, absence of link aggregation or redundant LAN, and the relatively immature UGOS Pro software, which trails behind DSM and QTS in terms of advanced features, third-party app support, and overall refinement. Still, for users seeking a reliable, efficient, and feature-packed NAS at a competitive price, the DH4300 Plus represents a compelling option that punches well above its weight—offering core functionality, multimedia capabilities, and surprising hardware strength without venturing into high-end NAS pricing territory.

UGREEN DH4300 NAS Review – Design and Storage

The UGREEN DH4300 Plus adopts a minimalist, vertical chassis design that blends functional cooling with a relatively compact footprint. Measuring 155mm x 155mm x 215.7mm, the enclosure is tall and narrow, allowing it to accommodate four internal 3.5″ or 2.5″ SATA drives without consuming significant desk space. Instead of traditional hot-swappable trays, UGREEN uses a toolless drive insertion mechanism where each drive slides vertically into the chassis.

This approach reduces complexity and keeps production costs lower but introduces compromises in terms of drive handling and vibration isolation. The top panel is removable and held magnetically, granting access to the internal drive bays and initial setup QR code sticker located inside the lid. Ventilation is handled by side vents, perforations at the top of the cover, and a single downward-facing internal fan near the system board.

Drive installation is simple but not entirely refined. Each of the four bays inside feeds directly into a fixed SATA backplane. Drives are inserted vertically without caddies and seat against rubber bumpers at the rear, which help reduce some of the mechanical vibration but do not provide the same structural integrity or thermal separation found in more traditional hot swap and more easily accessible tray-based designs.

The plastic inner rails feel light and somewhat fragile, especially when compared to metal-based bays found in more premium NAS models. Still, the internal structure was found to be sufficient during testing, even when populating the system with higher-capacity drives. The unit officially supports up to 4 x 30TB drives, allowing a total storage capacity of 120TB in JBOD or RAID configurations, though users will need to supply their own disks as none are included in the package.

Airflow and thermal behavior of the DH4300 Plus are managed via passive intake vents and a single active cooling fan positioned on the base of the chassis. This fan draws air from the top and sides of the NAS, passing it over the CPU and power delivery components before exhausting out the bottom. While this layout is thermally efficient for a low-power device like this, it lacks redundancy and doesn’t allow for custom fan curve profiles within UGOS Pro.

During 24-hour tests with four IronWolf drives installed, drive temperatures remained between 44°C and 45°C, while the system chassis and CPU areas stayed in the range of 38°C to 42°C under typical workloads. Though these temperatures are within operational thresholds, users deploying the NAS in warmer environments or fully populating it with high-RPM drives may need to consider ambient airflow or active external cooling assistance.

The DH4300 Plus is constructed from a mix of metal and plastic materials, with a soft matte finish and minimal front I/O clutter. This helps the device appear more neutral in office or home setups. All primary status LEDs are located subtly on the front edge, along with a power button and high-speed USB-C port. Despite its budget positioning, UGREEN has maintained an external aesthetic that doesn’t look out of place beside other premium tech. However, internal cost-saving decisions are more evident. The lack of a proper drive locking mechanism or hotswap support reinforces that this NAS is not meant for heavy-duty enterprise usage or high-frequency drive replacement tasks. It is more appropriate as a near-permanent local storage solution once disks have been installed and configured.

In terms of storage functionality, the DH4300 Plus supports multiple RAID modes, including Basic, JBOD, RAID 0, 1, 5, 6, and 10. This flexibility is notable, as several competing ARM-based NAS units limit RAID options—particularly RAID 6, which requires higher CPU and memory resources to compute parity. While software RAID performance will depend heavily on the chosen configuration and disk types, the Rockchip RK3588 SoC proved capable of maintaining consistent performance in RAID 5 across moderate workloads, including file copying, media playback, and snapshot operations. UGREEN’s system also offers automatic drive recognition and formatting through the UGOS Pro interface, allowing less experienced users to get started quickly, though without the advanced data scrubbing and repair features available on some higher-end NAS platforms.

UGREEN DH4300 NAS Review – Internal Hardware

At the heart of the DH4300 Plus lies the Rockchip RK3588 processor, an 8-core ARM-based SoC featuring a hybrid core architecture. It combines four high-performance Cortex-A76 cores with four efficiency-oriented Cortex-A55 cores, providing a significant performance uplift over most ARM-based NAS processors in the same price bracket. The RK3588 includes a Mali-G610 GPU and an integrated NPU capable of delivering up to 6 TOPS of AI performance. This allows for features like facial recognition, object tagging, and scene categorization within UGOS Pro. Notably, this chip has seen growing popularity in DIY NAS and edge computing applications due to its multimedia capabilities and low power draw. Its inclusion in a turnkey NAS platform at this price point positions the DH4300 Plus as an outlier among typical value-series offerings.

Complementing the processor is 8GB of LPDDR4X memory, which is soldered to the board and not user-upgradable. While this limits long-term scalability, 8GB is a generous amount for an ARM-based NAS and sufficient for most general-purpose NAS workloads including file sharing, media serving, AI-assisted photo sorting, and light Docker container deployment. The system also features a 32GB eMMC module, serving as a dedicated system drive for UGOS Pro. This separation of the OS from user storage pools ensures stability during boot and updates while also freeing up the full capacity of installed SATA drives for data. The lack of NVMe or SATA DOM options means the eMMC is fixed, but in practice, it performed reliably during testing without any bottlenecks.

From a thermal and power standpoint, the RK3588 platform proves to be highly efficient. Even under moderate to heavy loads—such as simultaneous file transfers, streaming tasks, and indexing—the SoC maintains stable temperatures in the low 40s Celsius range. Combined with a modest power draw of around 30–35 watts under active use (and ~4.7 watts at idle without drives), the DH4300 Plus is suitable for continuous 24/7 operation in home or office environments. While the lack of ECC memory or redundant power limits its appeal for enterprise deployment, the core hardware is well-balanced for its target audience, especially when considering how much performance and functionality is packed into a device with a sub-$400 price point.

UGREEN DH4300 NAS Review – Ports and Connections

The UGREEN DH4300 Plus offers a streamlined but functionally adequate set of connectivity options for a value-focused NAS. On the front of the device, users will find a USB-C port rated at 5Gbps, accompanied by two additional USB-A ports on the rear capable of 10Gbps transfer speeds. These high-speed USB ports are somewhat unusual on an ARM-based NAS and allow for faster direct-attached storage backups or peripheral integration, including UPS management or external media access. While not hot-swappable in the OS UI, the ports performed reliably in tests when mounting USB SSDs and thumb drives for quick file transfer and offline sync. Their positioning also maintains a tidy cable layout, with most high-traffic connections located on the back panel.

Network connectivity is delivered through a single 2.5GbE RJ45 port, which represents a solid step above the standard 1GbE ports found on most entry-level NAS units. This allows the DH4300 Plus to exceed typical Gigabit transfer speeds, reaching up to ~280MB/s in peak file transfer tests using large sequential data. However, the inclusion of only one LAN port means there’s no support for link aggregation or failover. This limits the device’s flexibility in multi-user environments or scenarios requiring redundancy. Given the hardware capabilities of the RK3588 platform, a second LAN port—or even a fallback 1GbE—would have been ideal. Still, for a single-user or small team deployment, the 2.5GbE connection is more than sufficient for everyday access to large media files, backups, and collaborative workspaces.

One of the most unexpected and welcome features is the presence of an HDMI 2.1 output, capable of 4K at 60Hz. HDMI on value-tier NAS systems is uncommon, and its inclusion here enables media playback, real-time NAS control via a directly connected monitor, and potential kiosk or signage applications. The UGOS Pro operating system includes a built-in theater mode to pair with this feature, although its capabilities are more basic than those found in platforms like QNAP’s HD Station. Nevertheless, for users wanting to leverage the NAS as a lightweight local media center or for on-site admin access without relying solely on browser-based control, the HDMI output adds flexibility. The only caveat is that the device lacks any form of PCIe expansion, so users cannot add additional ports or NVMe caching options later.

Port Type Specification
LAN 1 x 2.5GbE RJ45
USB-C (Front) 1 x USB 3.2 Gen 1 (5Gbps)
USB-A (Rear) 2 x USB 3.2 Gen 2 (10Gbps)
HDMI Output 1 x HDMI 2.1 (4K 60Hz)
PCIe Expansion None
Drive Interface 4 x SATA III (direct backplane)
Power Input 12V / 6A DC barrel connector

And for those concerned about noise, the system was surprisingly low noise, for it’s scale. It will, of course,e depend on the kind of drives you use (anything above around 12TB in a 4 disk configuration will likely be louder than the system fans, regardless), but the UGOS NAS software also has some level of fan control (low/high) too which can be adjusted if needed. Overall, the noise level was pretty good for a 4 disk NAS.

UGREEN DH4300 NAS Review – Software and Services

The DH4300 Plus runs UGOS Pro, UGREEN’s proprietary NAS operating system tailored for ARM-based platforms. While it doesn’t match the feature depth of more mature systems like Synology DSM or QNAP QTS, UGOS Pro has seen steady improvements and now covers most of the foundational functions expected from a modern NAS. The UI is browser-accessible and includes modules for storage management, user permissions, cloud sync, backups, and multimedia playback. During testing, the OS handled basic setup, RAID initialization, and file system formatting efficiently. Users can configure shared folders, enable SMB/NFS/AFP protocols, and even set up multi-tiered backup routines to local, USB, or cloud destinations such as Google Drive and Dropbox.

One of the more advanced features is the integrated AI photo engine, which leverages the RK3588’s NPU to organize media libraries using facial recognition, object tagging, and scene classification. This is similar in principle to what Synology Photos or QNAP QuMagie offer, though UGOS Pro lacks the same level of customization or filtering depth. The system can automatically generate albums, identify duplicates, and even create baby-focused timelines.

These features worked reliably on smaller photo sets but began to slow down when indexing larger libraries—likely a result of both memory and algorithmic efficiency. Despite this, the inclusion of AI functionality in a sub-$400 NAS is notable, especially since it runs locally and does not require cloud processing.

Application support is growing within UGOS Pro. Native apps for file access, media playback, surveillance (limited), and mobile sync are included, along with support for Docker containers, allowing users to sideload additional tools not officially available. Notably, BTRFS is supported as a file system option, enabling snapshot functionality and some degree of data integrity checks. However, there are limitations: virtualization is not supported due to the ARM architecture, and there’s currently no iSCSI target support.

Additionally, while the broader UGREEN ecosystem includes a Jellyfin app for other devices, this model did not have native Jellyfin support at launch—requiring users to deploy it manually via Docker. Features like multi-factor authentication, scheduled shutdown/start, and remote access are included, but power users may find the interface lacking compared to more polished systems.

The UGREEN DH4300 Plus delivers respectable media performance when running Jellyfin, particularly with 1080p and 4K content. During testing, the system handled native playback of 4K files smoothly and managed light transcoding tasks without excessive CPU strain, thanks to the efficiency of the RK3588’s integrated GPU and NPU. Native playback of 8K media was technically possible, but pushed the CPU usage to 70–75%, and any attempt at transcoding 8K content resulted in the processor maxing out at 100%, making it unsuitable for high-resolution real-time conversion.

While the NAS can serve 8K files over the network for compatible client playback, its ARM-based architecture lacks the raw transcoding power and hardware acceleration frameworks seen in x86-based systems with Intel Quick Sync. For most users, 1080p and 4K Jellyfin playback—both native and lightly transcoded—is handled reliably, but 8K should be considered the upper limit of what the DH4300 can manage, and only under specific playback conditions without conversion.

UGREEN DH4300 NAS Review – Verdict and Conclusion

The UGREEN DH4300 Plus carves out a unique niche in the budget NAS landscape by delivering hardware typically reserved for higher-tier systems at a much lower price point. Its RK3588 processor, 8GB of RAM, and support for 2.5GbE networking place it well ahead of most similarly priced competitors in terms of raw specifications. Additionally, features such as HDMI output, 10Gbps USB ports, and local AI-powered photo indexing are rare to find in entry-level NAS systems. Despite its plastic-heavy internal design and lack of expansion options like PCIe or M.2, the device delivers stable performance for file sharing, media access, and low-intensity AI workloads. It is not suited for power users demanding virtual machines or advanced snapshot automation, but within its class, the DH4300 Plus presents an appealing balance between cost and capability.

That said, the software experience is still a work in progress. UGOS Pro covers the essentials and offers a visually accessible UI, but lacks the advanced features and ecosystem integration found in more mature platforms like Synology DSM or QNAP QTS. Docker and snapshot support add welcome flexibility, but the absence of native Jellyfin, iSCSI, and VM functionality limits its use in more complex environments. Still, for home users, media collectors, or small office setups looking for reliable backup, modest AI-enhanced photo sorting, and smooth 4K playback, the DH4300 Plus delivers value well beyond its price tag. While it won’t replace high-end NAS appliances, it serves as a capable, efficient, and quietly innovative option in a saturated entry-level NAS market.

UGREEN DH4300 and DH2300 NAS Revealed – Good Value?

Par : Rob Andrews
10 juillet 2025 à 16:00

New Value Series UGREEN DH4300 and DH2300 NAS Drives

UGREEN has unveiled two new value-focused NAS devices, the DH3400 and DH3200, designed to meet the needs of home and small office users who want practical, low-power network storage without unnecessary complexity. The DH3400 is a 4-bay model, while the DH3200 offers a 2-bay configuration, both intended for those looking to implement efficient backups, multimedia streaming, and personal cloud storage at a more affordable price point. First revealed through the 2025 iF Design Awards and then quietly launched with a limited discount during Amazon Prime Day, these models occupy a lower tier in UGREEN’s NAS range, complementing rather than replacing their existing higher-end DXP series.

These two devices clearly target users who prioritize straightforward functionality over high-end processing power or advanced virtualization. Both systems are engineered with energy-efficient components and a compact design that makes them suitable for desktop environments where noise, heat, and power consumption need to be minimized. By offering a clear set of features—including RAID support, snapshot capabilities, and 4K multimedia output—at a modest price, the DH3400 and DH3200 aim to appeal to customers who need reliable, low-maintenance storage hardware that can integrate easily into a home network or small office setup.

UGREEN DH2300 and DH4300 NAS Hardware Specifications

The UGREEN DH3400 and DH3200 are built on a shared hardware platform, with the key difference being drive bay count—four bays on the DH3400 and two on the DH3200. Both systems use the Rockchip RK3588C processor, an 8-core ARM-based SoC running at 2.4 GHz, designed to prioritize energy efficiency and low thermal output rather than raw performance. The RK3588C includes integrated Mali-G610 graphics and an AI engine capable of delivering up to six tera operations per second (TOPS), which enables features like facial recognition and semantic photo search without taxing the CPU as much as it would likewise ARM processors without it.

Feature DH3400 (4-Bay) DH3200 (2-Bay)
CPU Rockchip RK3588C, 8-core ARM, 2.4 GHz Same
GPU Mali-G610 integrated graphics Same
AI Engine Up to 6 TOPS Same
Memory (RAM) 8 GB LPDDR4X (non-upgradable) Same
System Storage 32 GB eMMC (OS pre-installed) Same
Drive Bays 4× SATA (3.5”/2.5”) 2× SATA (3.5”/2.5”)
Maximum Capacity 120 TB (4× 30 TB) 60 TB (2× 30 TB)
Supported RAID JBOD, Basic, RAID 0/1/5/6/10 JBOD, Basic, RAID 0/1

USB Ports 1× USB-C (10 Gb/s), 2× USB-A (10 Gb/s) Same
HDMI Output 1× HDMI 2.0 (4K@60Hz) Same
Power Supply 12V/6A Same
Dimensions (mm) 155 × 155 × 215.7 Similar, slightly shorter
PCIe Expansion Not supported Not supported
M.2 NVMe Slots Not supported Not supported

This processor choice underlines UGREEN’s intent to offer a quiet, cool, and power-conscious NAS for everyday workloads such as file storage, multimedia streaming, and light AI-assisted tasks – at least compared with their currently very successful DXP NASync Series. The architecture, however, does mean hefty hardware video transcoding and heavy virtualization are not part of its remit, which is appropriate for its role as an entry-level system or one designated as a network backup target for your current beefier NAS system!

Both units come equipped with 8 GB of soldered LPDDR4X memory, which cannot be upgraded. This is a typical limitation of ARM-based NAS systems, where memory is tightly coupled with the SoC for efficiency. The onboard memory is adequate for the included software stack, which supports multi-user environments, Docker containers, and AI-driven media management. For system storage, UGREEN integrates a 32 GB eMMC module to host the UGOS Pro operating system. This keeps the SATA bays fully available for user storage, though it does mean the system disk cannot be swapped or expanded.

The DH3400 supports up to four 3.5” or 2.5” SATA drives, while the DH3200 supports two, and both models can accommodate up to 30 TB per bay, for a maximum of 120 TB on the DH3400 when fully populated. Supported RAID configurations include JBOD, Basic, RAID 0, 1, 5, 6, and 10, providing a range of data protection and performance options suited to home and SOHO environments.

Networking and external connectivity are kept simple yet functional. Each system includes a single 2.5 GbE Ethernet port, which supports transfer speeds up to roughly 300 MB/s under optimal conditions. Although dual LAN ports for link aggregation or failover would have been welcome at this price point, the single-port setup is likely sufficient for the target audience.

Three USB ports are provided: one USB-C @ 5Gb/s and two USB-A @ 10 Gb/s. These are useful for connecting additional external drives, creating tiered backups, or quickly offloading data from portable devices. The inclusion of a full-size HDMI port capable of 4K/60Hz output is another notable feature, enabling direct connection to a monitor or TV for multimedia playback or system administration from a local display—something not all competing devices offer.

From a physical and design perspective, the DH series is clearly built to fit seamlessly into a home or small office. The DH3400’s chassis measures just 155 × 155 × 215.7 mm, and its vertical, injection-molded plastic design keeps its footprint compact and thermals manageable. Power consumption is modest at a rated 12V/6A, helping keep operational costs low and making the units suitable for 24/7 use.

The overall aesthetic is understated, drawing comparisons to earlier Western Digital consumer NAS devices, with a focus on quiet operation and minimal disruption to the workspace. While there is no support for PCIe expansion or M.2 NVMe storage—features found in higher-end UGREEN DXP models—the streamlined hardware specification aligns with the device’s role as an affordable, efficient, and easy-to-deploy file server for users who don’t require more advanced features.

UGREEN DH2300 and DH4300 NAS Software Specifications

Both the DH3400 and DH3200 ship with UGREEN’s UGOS Pro operating system, a Linux-based NAS software platform designed to be user-friendly while offering a solid range of core functionality. UGOS Pro provides a clean, browser-based interface accessible from Windows, macOS, Android, iOS, web browsers, and even smart TVs, making it easy for users to manage their storage from almost any device. The OS supports secure multi-user access with advanced encryption, a built-in firewall, and two-factor authentication, ensuring that data remains protected from unauthorized access. Local data storage is emphasized over cloud reliance, though cloud backup targets are supported for redundancy.

In terms of features, UGOS Pro includes most of the essential applications expected of a modern NAS. File and folder management is straightforward, with support for SMB/CIFS, NFS, and WebDAV protocols. Users can set up scheduled or on-demand backups, including multi-tiered strategies spanning local drives, external USB storage, and supported cloud services. Snapshot functionality is included to help protect against accidental deletion or data corruption. Multimedia applications are also integrated, with tools for organizing and streaming photos, videos, and music, plus support for the HDMI output for direct 4K media playback on connected displays.

Despite being a value-oriented device, the DH3400 and DH3200 still offer some advanced capabilities thanks to the efficiency of the RK3588C CPU. These include AI-powered features such as photo recognition by faces, scenes, and locations, automatic duplicate removal, and the creation of personalized albums. Semantic search functionality helps users locate files more intuitively, and Docker is supported for lightweight containerized applications. However, resource-intensive functions like virtualization and more complex enterprise-grade apps are not included, in keeping with the intended role of these systems as affordable, entry-level NAS solutions. Plus, no doubt, the ease of integrating this more cost-effective solution with other, more powerful DXP NAS systems using the nativa backup sync application is going to be a breeze on the LAN!

UGREEN DH2300 and DH4300 NAS – Price and Launch Date?

UGREEN’s new DH2300 and DH4300 NAS models have already quietly launched, with availability beginning during Amazon Prime Day 2025 in what can best be described as a stealth release. The DH4300, the 4-bay model, is currently listed at $429.99 diskless, although a temporary promotional discount during Prime Day dropped the price as low as $349.99. At the time of writing, UGREEN has not provided an official end date for the promotional pricing, so buyers should assume the standard price is $429.99 going forward. The DH2300, the 2-bay variant, has not yet been widely listed, and official pricing for that model has yet to be confirmed. Both models are expected to continue rolling out to major online retailers over the coming weeks, with broader global availability likely to follow given UGREEN’s previous product launch patterns. For now, early adopters in supported regions can purchase the DH4300 directly from platforms like Amazon, and keep an eye on listings for the DH2300 to appear soon. Buyers should note that, as with most diskless NAS products, storage drives are sold separately. These models are positioned as affordable, efficient storage solutions in UGREEN’s lineup, complementing rather than replacing their existing DXP series. By offering a lower barrier to entry, UGREEN appears to be catering to users looking for basic yet capable NAS hardware at an accessible price. Those interested in purchasing should monitor retailer listings closely for availability and any further discounts as stock becomes more widely distributed.

Delete associated EBS snapshots automatically when deregistering an AMI in AWS EC2

10 juin 2025 à 22:00
AWS now allows automatic deletion of associated Amazon EBS snapshots when deregistering EC2 AMIs, reducing storage costs and simplifying cleanup. Previously, snapshots had to be manually deleted, risking orphaned resources. This feature is long overdue. In a previous post, I introduced a Bash script that deleted the snapshot when an AMI was deregistered. The script should still work, but now you can automatically delete snapshots in the AWS Console and the AWS CLI.

Mount an S3 bucket on an EC2 instance at boot using fstab with Mountpoint for Amazon S3 or s3fs-fuse

5 juin 2025 à 17:51
Mountpoint for Amazon S3 (mountpoint-s3) now allows you to mount an S3 bucket in AWS at EC2 instance boot time via fstab. However, it remains non-POSIX compliant, so standard filesystem operations like deleting or renaming files still do not work. In contrast, the open-source alternative s3fs-fuse offers substantial POSIX support but comes with its own drawbacks.

Clear DirectX Shader Cache in Windows 11: Top Ways

8 mars 2024 à 14:19

Windows 11 is a robust operating system with a host of features, especially optimization features. In this guide, we explore one of them, the DirectX Shader Cache in Windows 11, and show you all the different ways to clear it when needed.

What is DirectX Shader Cache in Windows 11?

On Windows 11, the DirectX Shader is the optimization feature for storing pre-compiled versions of special instructions, which are called shaders.

Shaders are tiny programs that your graphics card understands. These programs direct the graphics card’s handling of various graphical effects.

Compiling these shaders may be time-consuming, so the cache increases optimization because pre-compiled versions are easier and faster to access.

Should I Clear the DirectX Shader Cache?

Your decision to clear the cache will depend on you. However, below are some reasons why you may want to do so.

  • To resolve performance issues – A cleared DirectX Shader cache may resolve some performance issues, including graphical glitches and stuttering.
  • Freeing up disk space – Even though the cache may not take up much space, clearing it will still free up some extra space on your computer.
  • To update the cache – If you have just updated your graphics card or installed new games, you may clear the DirectX Shader cache to fill it with new information.

How do I Clear the DirectX Shader Cache?

1. Using the Settings App

1. Lunch the Settings app by clicking Windows + I.

2. Navigate System, then Storage.

Do I Have to Replace the DirectX Shader Cache After Deleting It?

No, you do not have to replace it. After this cache is deleted, your operating system will automatically fill it with all the needed information.

You should also note that clearing the cache is not something you must do often. It is mainly a troubleshooting step when you face some graphical issues.

A New DirectX Shader Cache

This is all we share in this guide. If you have followed from the beginning, you already know all there is to know about the cache, and you probably already have a new DirectX Shader cache.

Were you able to clear the DirectX Shader Cache in Windows 11? Ask your questions in the comment section below.

FAQs

Does clearing the cache affect system stability?

No, this procedure will not negatively affect your system. This is because the cache is isolated storage with no permanent information.

Is it possible to disable or prevent the creation of the DirectX Shader Cache?

Windows 11 has no official way of disabling this optimization feature.
