GMKTec G9 NAS (New Improved Cooling Version) Review

Important – My original review of the GMKTec G9 NAS in it’s original design can be found HERE on YouTube and HERE on the NASCompares blog.

The GMKTec G9 NucBox NAS has re-emerged in mid-2025 with a revised cooling design, following a wave of thermal criticism directed at the original release earlier in the year. Still marketed as an SSD-only NAS aimed at home and small office environments, the G9 maintains its core identity—a compact enclosure powered by Intel’s N150 quad-core processor, soldered LPDDR5 memory, and four M.2 NVMe SSD bays. The G9’s primary appeal continues to be its affordability, silent operation, and dual-use flexibility as both a NAS and lightweight desktop system, thanks to the inclusion of Windows 11 Pro and Ubuntu out of the box. However, early buyers and reviewers, including this channel, highlighted persistent thermal issues affecting SSD performance and overall system reliability under load, leading to thermal throttling even during idle states in warmer environments.

In response, GMKTec has issued an updated version of the G9 that retains the same form factor, internal hardware, and I/O but incorporates enhanced passive ventilation on the side and top panels. Though subtle at first glance, these structural changes are designed to improve airflow over the CPU and SSD compartments without increasing noise levels or power draw. In this updated review, we will revisit all aspects of the G9’s design, connectivity, and system behaviour under continuous load, while highlighting what exactly has changed and what remains untouched. The new G9 model introduces targeted thermal improvements, but beyond ventilation, it leaves the original architecture and feature set entirely intact.

GMKTec G9 Ver.2 NAS Review – Quick Conclusion

The improved GMKTec G9 NAS represents a targeted refinement rather than a full redesign, addressing the primary weakness of the original model: inadequate thermal performance. The updated version introduces enlarged ventilation cutouts on the top panel above the CPU fan and replaces the pinhole rear exhaust with a wider mesh, leading to measurable but modest reductions in system temperatures. In 48-hour test scenarios using UnRAID with hourly backup tasks, SSDs without heatsinks in the original unit reached idle temperatures of 66–67°C, while the revised model brought this down to 56–57°C. CPU vent temperatures similarly dropped from 54–56°C to 50–52°C, and rear I/O areas cooled by 5–7°C. These improvements enhance stability during sustained I/O activity but do not eliminate the need for additional SSD cooling—particularly in environments where ambient heat or multi-user access is expected. Internally, the hardware remains unchanged: Intel N150 CPU, 12GB of non-upgradable LPDDR5 memory, four PCIe Gen 3 x2 M.2 NVMe bays, and dual 2.5GbE ports, with storage and network throughput consistent with entry-level expectations. Power consumption remains efficient (19–30W), and noise levels stay low at under 40dB, making it suitable for always-on deployment. However, the continued use of a plastic chassis and base panel still limits effective heat dissipation, and the absence of thermal sensors or fan curve controls further limits its thermal adaptability. Compared to the Xyber Hydra—featuring a metal base, better SSD thermal contact, and 16GB RAM—the G9 now performs better than before but still falls short of what its hardware could achieve with more thoughtful engineering. For users willing to invest in SSD heatsinks and mindful of its limitations, the G9 is now a reasonably balanced entry NAS, though not the strongest performer in its tier.

GMKTec G9 Ver.2 NAS Review – Design and Storage

The GMKTec G9 continues to use a compact, matte-black plastic chassis that is closer in design to a mini PC enclosure than a traditional NAS. The vertical design conserves desk space, and the front-facing panel remains clean and understated, with no visible drive trays or status indicators beyond the power button and basic branding. As with the original model, the chassis sacrifices the durability and thermal advantages of metal in favour of a lightweight, cost-efficient build. This makes the device appealing for users with space constraints, but it also signals the system’s budget positioning. The plastic enclosure, while solid enough for day-to-day use, is not especially resistant to heat buildup during sustained I/O operations, which remains one of its most persistent limitations.

Internally, the system supports four M.2 NVMe SSDs, each connected via PCIe Gen 3 x2 lanes. This setup allows up to 32TB of total SSD storage, assuming the use of high-capacity 8TB NVMe drives. The use of SSDs rather than traditional 2.5″ or 3.5″ hard drives enables near-silent operation, faster access times, and lower power consumption. However, SSD-only NAS designs like this one typically require better airflow and heatsinking to mitigate thermal throttling—especially during RAID operations or when used as a media server with multiple concurrent reads and writes. The G9 supports basic RAID via third-party NAS OSs, but due to PCIe lane limitations and lack of onboard RAID management, advanced configurations will rely entirely on software.

One of the primary complaints in the original model was the absence of SSD heatsinks and the system’s poor natural heat dissipation. While pre-built units from GMKTec occasionally shipped with low-profile aluminum heatsinks, user-added drives often ran hot, especially under sustained write loads. The M.2 slots sit stacked vertically inside a cramped compartment behind the lower rear panel, and when combined with a sealed plastic baseplate, heat quickly accumulates. This design still persists in the new version, and although airflow has been improved through the external vents, the interior thermal behaviour remains heavily dependent on user-supplied heatsinks and ambient cooling conditions. Users deploying high-endurance SSDs or running frequent write-intensive tasks will need to factor this into their thermal strategy.

The internal layout is efficient but fixed. There are no modular trays or hot-swap capabilities for the SSDs, and all upgrades must be performed by opening the device. Memory is soldered and therefore non-upgradable, and while there’s internal eMMC storage used for the pre-installed OS, most users will opt to install TrueNAS, UnRAID, or OpenMediaVault onto one of the NVMe drives for full NAS functionality. The passive cooling approach is unchanged in its core design: two internal fans (one for CPU, one system) move air through the case, but without direct thermal contact to the SSDs or a conductive enclosure material, this airflow has limited reach. Placement of the unit in a well-ventilated space remains essential.

The only real physical design changes in the new version are to the external ventilation panels. GMKTec has replaced the original pinhole-style vent on the rear side with a wider mesh grille, which now spans a greater portion of the side panel. Additionally, the top panel has been revised to include a broader cutout directly above the CPU fan, allowing a clearer exhaust path for rising hot air. However, the plastic base and internal heat chamber structure remain unchanged, meaning SSD temperatures are still a potential concern—especially without aftermarket cooling. The updated G9 retains the same core storage architecture as the original, but introduces modest improvements to airflow via enhanced external ventilation.

GMKTec G9 Ver.2 NAS Review – Internal Hardware

At the center of the GMKTec G9 is the Intel N150 processor, a quad-core, four-thread CPU built on the 10nm Twice Lake architecture. Designed for ultra-efficient computing, it operates at a modest 6W TDP, making it ideal for passive or semi-passive cooling environments like compact NAS systems. The N150 runs at a 1.0GHz base frequency and boosts up to 3.6GHz under load, delivering just enough headroom for tasks like SMB/NFS sharing, low-volume web hosting, and basic media playback. Its integrated Intel UHD Graphics support up to 4K at 60Hz output via HDMI or USB-C DisplayPort alt mode, though without hardware acceleration for modern codecs like AV1, its suitability for on-the-fly transcoding is limited. The CPU also lacks advanced server-grade features like ECC memory support, SR-IOV, or high-bandwidth PCIe 4.0 lanes, which reflects its role in cost-conscious, entry-level applications.

The onboard 12GB of LPDDR5-4800 memory is soldered and cannot be replaced or upgraded, a design choice that simplifies manufacturing and keeps costs down but limits versatility in heavier multitasking scenarios. In practice, the memory is sufficient for running one or two lightweight NAS services alongside file sharing, or even a basic Docker container or two, but its soldered configuration leaves no room for future expansion. Notably, the memory is dual-channel, which does help offset some performance constraints—especially in scenarios where the integrated graphics or CPU requires memory bandwidth access. While most users won’t hit the ceiling of 12GB under standard NAS tasks, advanced setups involving active sync with cloud platforms, large-scale Plex libraries, or multiple concurrent rsync/FTP sessions could find the limitation restrictive. Also, unlike some similarly priced competitors, there’s no accessible BIOS option to reserve RAM for cache acceleration, which could have improved responsiveness under heavier I/O loads.

In terms of storage hardware, the G9 offers four M.2 NVMe slots with PCIe Gen 3 x2 interfaces, a configuration that supports up to 32TB of total storage using current consumer-grade drives. Each slot is keyed for M-Key NVMe SSDs and arranged vertically inside the enclosure, though installation requires unscrewing the rear panel and working within the confined internal cavity. The system’s internal PCIe lane distribution is handled through multiple ASMedia ASM1182e switch chips, which divide the CPU’s limited PCIe bandwidth across all four NVMe slots and the dual 2.5GbE interfaces. While the Gen 3 x2 interface is technically capable of 2GB/s per slot, real-world speeds are often lower during concurrent access due to the shared architecture.

This design also limits SSD passthrough capabilities in virtualized environments, and users aiming for high-speed SSD RAID configurations (RAID 5 or 10, for example) may encounter inconsistent write speeds. Additionally, there is no hardware-level thermal throttling safeguard tied to fan curves or SSD temperature sensors, so thermal build-up under load could directly affect sustained throughput unless active cooling measures are installed. The internal hardware of the improved GMKTec G9 remains completely unchanged from the original release—no CPU, RAM, SSD slot layout, or controller chip has been altered in the updated version.

GMKTec G9 Ver.2 NAS Review – Ports and Connections

The GMKTec G9 offers a well-rounded I/O configuration that reflects its hybrid role as both a compact NAS and lightweight desktop appliance. It features two 2.5GbE LAN ports, both of which are directly linked to the CPU via PCIe lanes and can be configured for link aggregation, failover, or isolated network segments. In real-world testing, these ports easily saturate their 312MB/s bandwidth under SMB and iSCSI workloads, making the G9 more capable than traditional Gigabit NAS units. The absence of 10GbE is notable, especially for users planning to deploy NVMe RAID arrays or work in content-heavy environments, but at this price point and power envelope, dual 2.5GbE is still a competitive offering. Notably, both NICs support Wake-on-LAN (WoL), making the system convenient for remote access or low-power automation setups.

For peripheral and expansion support, the G9 includes three USB-A 3.2 Gen 2 ports and a single USB-C 3.2 Gen 2 port, each capable of 10Gbps data transfer. The USB-C port also supports DisplayPort Alt Mode, allowing it to function as an additional video output alongside the two HDMI 2.0 ports on the rear panel. These HDMI ports support 4K resolution at 60Hz and are positioned for users who may wish to operate the G9 as a silent desktop system or a local media playback device via Kodi, Jellyfin, or Plex. However, the G9 does not include USB 4.0, Thunderbolt, or PCIe expandability, limiting options for future upgrades such as external GPUs, additional NICs, or DAS enclosures. In testing, connected peripherals such as USB drives and webcams were recognized instantly under Ubuntu and Windows, confirming basic plug-and-play compatibility.

Power delivery is handled via USB-C PD input, using a 65W external power brick that ships with the unit. Uniquely, the updated G9 introduces a small but notable change: dual USB-C power input points, allowing users to select which side of the device receives the power cable. This change doesn’t increase power capacity or enable redundancy, but it can improve cable management depending on the G9’s orientation on a desk or shelf. However, using one of the USB-C ports for power inherently sacrifices a high-speed data port—an unfortunate trade-off given the unit’s lack of PCIe or expansion bays. No dedicated power switch is present; the unit powers on via the front button or Wake-on-LAN and remains always-on unless shut down via software or OS-level scripts. Compared with the original G9, the only change to I/O is the addition of the second USB-C power input for layout flexibility—otherwise, all ports, speeds, and layout remain the same.

GMKTec G9 Ver.2 NAS Review – Tests and Performance

In synthetic and real-world benchmarks, the GMKTec G9 delivers the level of performance expected from an Intel N150 system with PCIe Gen 3 x2 storage. Read speeds per drive peaked around 1.4–1.5GB/s, aligning well with the theoretical limit of the x2 interface. Write speeds were notably more volatile, ranging between 400–600MB/s depending on SSD type, ambient temperature, and active processes. These numbers, while adequate for file serving, backups, and Docker apps, showed clear limitations when the system was pushed into simultaneous multi-disk writes or parity-based RAID configurations. The presence of ASMedia ASM1182e PCIe switches likely contributes to this variance, as downstream PCIe allocation under pressure introduces contention among the SSD lanes. In typical NAS tasks like SMB and NFS file transfers, however, performance remained consistent and stable, particularly when network activity was confined to single-user access or sequential transfers.

Thermal behaviour is where the most scrutiny falls, given the G9’s original design flaws. Under a controlled 48-hour test using UnRAID with scheduled hourly backups and mixed-use read/write activity, the older G9 unit routinely idled at 54–56°C, with peaks of 66–67°C on SSDs lacking heatsinks.

The improved model saw modest thermal gains, with idle temps reduced to 50–52°C at the CPU vent and around 56–57°C on the SSD layer. Some of this improvement came from the revised ventilation—namely the expanded top-panel fan cutout and rear-side mesh panel—yet the base remained the same thermally isolated plastic panel, and internal fan hardware remained unchanged.

Notably, temperatures around the rear I/O ports dropped by 5–7°C between versions, suggesting that airflow efficiency around the motherboard has improved even if core thermal load remains a challenge.

In terms of noise and power, the G9 performs admirably. Even under load, fan noise remained below 40dB, with idle operation being nearly silent. Power consumption remained within the expected range—19–21W idle and up to 30W under continuous activity—even during the 48-hour write test.

BIOS-level tuning is possible and can slightly reduce power draw or adjust fan thresholds, but no advanced power scaling or fan curve customization is exposed via software in stock OS images. More demanding operating systems like TrueNAS Scale ran stably on the G9 but did little to mitigate thermal behaviour, reinforcing the importance of user-added SSD heatsinks regardless of OS.

The lack of thermal sensors per SSD slot or fan feedback control means sustained operations should be closely monitored in hotter climates or enclosed environments.

Nowhere is the conversation about thermal and hardware design more relevant than in comparison to the Xyber Hydra, a near-identical system that appears to share much of its component sourcing with the G9—right down to the GMK-branded fans. The Hydra ships with 16GB of DDR5 memory, a metal base panel, and most notably, a thermal pad that bridges SSDs to the metal shell, allowing for actual heat transfer rather than passive convection. In direct tests, the Hydra consistently posted 5–10°C lower SSD temps under identical workload, with idle SSDs (no heatsinks) registering around 47–49°C versus 56–57°C in the improved G9.

Though the Hydra lacks branding clarity around its manufacturer, the design appears to be what the G9 should have evolved into: same layout and CPU, but better thermals, more memory, and more thought put into SSD dissipation. In conclusion, while the improved GMKTec G9 offers better thermals than its predecessor, the Xyber Hydra outperforms both G9 variants in every thermal category, making it the superior choice if cooling and memory capacity are priorities.

GMKTec G9 Ver.2 NAS Review – Verdict and Conclusion

The GMKTec G9, in its improved form, shows that the brand has listened—albeit cautiously—to thermal concerns raised by users and reviewers of the original model. The changes introduced in this updated version are minimal but measurable: better ventilation on the top panel and side mesh grille allow modest airflow gains, which result in lower surface and SSD temperatures across the board. Yet, GMKTec has stopped short of making any internal or structural upgrades that would more directly resolve thermal issues, such as introducing a metal baseplate, bundling SSD heatsinks, or adjusting the system’s internal fan architecture. All other hardware elements—CPU, memory, SSD configuration, I/O, BIOS, and software readiness—remain identical. As a result, while the device performs better in heat dissipation than before, it does so by a margin that may not justify an upgrade for existing G9 users. First-time buyers, however, may find it to be a safer choice now—particularly when paired with aftermarket heatsinks and used in moderate workloads.

However, the presence of the Xyber Hydra in the same price bracket poses a critical challenge to the G9’s value proposition. Offering the same N150 CPU, more memory, and a far superior thermal design with an integrated metal heat-spreading base, the Hydra addresses nearly every lingering complaint about the G9 without altering the system’s core layout. For prospective buyers deciding between the two, the G9’s only advantages now lie in its wider availability, slightly more recognizable branding, and marginally more mature firmware support. If those factors matter less than thermal reliability, long-term SSD health, and RAM headroom, then the Hydra is the more complete solution. Ultimately, the improved GMKTec G9 is a more stable and better-performing version of its former self, but its restrained upgrades feel like a missed opportunity in a market where near-clones have already moved ahead in meaningful ways.

Xyber Hydra NAS Review

Note – there is going to be ALOT of comparisons with the GMKtec G9 Nucbox NAS in this review. This is because the Hydra is clearly either built in partnership with GMKtec, or at least using branded components from the same factory (see example below). Likewise given this system’s similarity to the G9 and attempts to improve upon the heat criticisms of that device, it is inevitable that comparisons need to be made. If you want to learn more on it, find out more HERE and HERE .

The Xyber Hydra N150 NAS is a compact, four-bay, flash-focused network storage appliance designed for home users, small-scale media servers, and lightweight virtualization or container workloads. It is powered by the Intel Twin Lake N150 processor, a quad-core, low-power x86 CPU with a 6W TDP, making it energy-efficient while still capable of handling NAS-centric tasks like 4K media playback and multi-client file sharing. The Hydra comes equipped with 16GB of fixed LPDDR5 memory, which is soldered directly to the mainboard, offering slightly more headroom than comparable systems like the GMKtec G9, which ships with 12GB. Out of the box, it includes a 64GB eMMC module with Ubuntu OS pre-installed and ready to boot, enabling first-time users to deploy it with minimal setup. At an introductory price of $218.99, it is one of the more affordable quad-core NAS units in its category, and it even arrives with a 512GB M.2 SSD pre-installed in one of its four PCIe Gen 3×2 slots, saving buyers the immediate cost of adding their own storage.

Although visually and structurally similar to the GMKtec G9, with identical port layouts, vent positions, and internal fans — even down to the GMK-branded fans noted during inspection — the Hydra differentiates itself with a more robust passive cooling solution, a thicker, heat-dissipating metal baseplate, and wireless connectivity that supports UnRAID out of the box. These small but meaningful changes target some of the criticisms of its predecessor while maintaining the same compact form factor and low power consumption, which are critical in a shared home or office environment.

Xyber Hydra NAS Review – Quick Conclusion

The Xyber Hydra N150 NAS positions itself as a compact, affordable, and feature-complete flash-based NAS for home and small office users who prioritize a balance of cost, usability, and functionality. Compared to similarly specced models like the GMKtec G9, the Hydra delivers several notable improvements, including a thicker metal base plate that provides superior passive cooling for the M.2 SSDs and overall system stability under load. The inclusion of 16GB of fixed LPDDR5 memory — higher than many competitors in this category — combined with a preinstalled 64GB eMMC module running Ubuntu and an additional 512GB NVMe SSD in Bay 1 means the device is immediately operational out of the box, requiring no initial storage or OS setup for those who prefer simplicity. The four M.2 NVMe bays each operate at PCIe Gen3 x2, and the system’s dual 2.5GbE ports with link aggregation, HDMI outputs, and Wi-Fi 6 support add flexibility for wired and wireless deployments. During testing, the device handled sustained read and write loads respectably, although full bandwidth potential is naturally limited by the Intel N150 CPU and the available PCIe lanes, which is expected at this price point. The soldered memory and non-upgradable RAM limit future scalability, and the cooling fans require manual adjustment in the BIOS to achieve optimal thermal dissipation during intensive workloads, but neither of these compromises is unusual in this segment. Overall, at its introductory price of $218.99, the Xyber Hydra provides a solid combination of improved thermals, ready-to-use OS and storage, and efficient flash performance in a small, quiet, and energy-efficient chassis — making it a practical choice for users who want a capable NAS solution without the complexities and cost of larger, enterprise-class systems.

Xyber Hydra NAS Review – Design and Storage

The Xyber Hydra N150 follows a minimalistic and highly compact design philosophy, measuring roughly 100mm square and slightly taller than most mini-PC NAS chassis to accommodate the four vertically-mounted M.2 SSD bays. It shares its external dimensions and general visual design with the GMKtec G9, including the placement of dual fans on the underside and venting around the periphery. However, unlike the G9, which uses a plastic bottom panel that does little to aid thermal dissipation, the Hydra replaces this with a solid, vented metal plate that doubles as a passive heat sink for the M.2 drives.

Internally, each M.2 bay is aligned with a pre-applied thermal pad that contacts directly with the thicker metal plate, promoting more even heat spread and helping to avoid the localized hot spots that were reported in earlier reviews of the G9.

The result is a chassis that retains the same small footprint and quiet operation while making better use of its passive cooling surfaces, critical in a flash-based NAS where SSD thermal throttling can become a bottleneck. The overall construction remains lightweight yet rigid, with the entire enclosure built around a metal alloy frame finished with a matte black exterior that resists fingerprints and blends well into modern home or office environments.

On the storage side, the Hydra offers four M.2 2280 NVMe slots, each rated for PCIe Gen 3×2 speeds — a slight but notable advantage over many competitors still using Gen 3×1 lanes per slot.

This configuration allows for theoretical single-drive bandwidths approaching 2GB/s, with practical performance in the range of 1.4–1.5GB/s reads and 1.1GB/s writes as observed in testing.

The system arrives preconfigured with a single 512GB NVMe SSD installed in Bay 1, providing an immediate usable pool of storage alongside the 64GB eMMC that hosts Ubuntu.

Importantly, the eMMC storage is mounted separately, leaving all four M.2 slots fully available for user expansion.

The choice of M.2 storage allows for dense, silent operation with lower power draw than traditional 3.5” or 2.5” drives, but it does limit hot-swapping and requires opening the chassis for upgrades or replacements — a trade-off typical of devices at this size and price point.

Additionally, the Hydra supports popular NAS operating systems beyond the preloaded Ubuntu, such as UnRAID and TrueNAS, which take full advantage of the NVMe-based array and facilitate different RAID configurations. One critical area of focus in the Hydra’s design is the improved thermal management compared to the G9. Temperature testing revealed clear improvements under both idle and sustained load conditions.

AS A REMINDER – THE TEMPS BELOW ARE FROM THE GMKTEC G9:

At idle, with the fans in automatic mode, the surrounding chassis temperature stabilized around 52–54°C, and the baseplate measured approximately 50–52°C after a 24-hour period of light access — respectable figures given the compact enclosure. Under heavier workloads, where all four SSDs were simultaneously subjected to repeated write tests, the baseplate peaked at 62°C with the CPU hitting full utilization. While this level of heat is not unusual for a fully-loaded NVMe NAS, the system took a long time — nearly five hours — to dissipate that heat and return to sub-50°C base temperatures when the fans remained in automatic mode. Switching to manual fan control in the BIOS and setting both fans to maximum brought the temperature down much more quickly, keeping the chassis in the mid-40°C range even under sustained load, albeit at the cost of increased noise and marginally higher power draw.

AND HERE ARE THE TEMPS OF THE XYBER HYDRA NAS FOR COMPARISON:

The improved thermal contact via the thicker metal plate and better thermal pads clearly mitigates some of the thermal throttling concerns seen in earlier systems with less effective heat spreaders.

AND HERE ARE THE TEMPS OF THE XYBER HYDRA NAS FOR COMPARISON:

Power consumption and noise measurements during testing demonstrated the efficiency of the Twin Lake platform. In an idle state with the system fully populated with four NVMe drives and minimal CPU activity (4–6% utilization), power draw stayed at a modest 15.6–15.7 watts. During full-load scenarios, including simultaneous writes to all four SSDs and 100% CPU utilization with fans at maximum, peak power consumption rose to around 26–27 watts.

These figures are reasonable for a small-form-factor NAS and illustrate the platform’s balance of performance and efficiency. Acoustic levels were similarly modest: at idle with fans on automatic, noise levels measured between 30–32 dBA, increasing to 37–38 dBA when the fans were manually set to maximum in the BIOS. This makes the system viable for use in environments where low noise is desirable, without sacrificing much in the way of cooling when needed.

Another noteworthy design element is the inclusion of a Wi-Fi 6 module with two antennas, offering wireless connectivity that is now supported by UnRAID. The wireless module sits beneath the eMMC module and is connected internally without consuming any of the four NVMe slots. This makes it possible to deploy the Hydra wirelessly, adding flexibility in environments where cabling is limited, though for maximum bandwidth the dual 2.5GbE ports remain preferable. The antennas are discreetly mounted to the rear of the chassis, maintaining the device’s clean lines and compact appearance.

The Hydra’s design prioritizes compactness, quiet operation, and efficient use of its internal volume. The choice of an all-NVMe storage configuration, preloaded OS on eMMC, and improved passive cooling all contribute to making it a more capable and thermally balanced alternative to similar NAS devices. The metal baseplate, though seemingly a small change, represents a meaningful improvement in reliability for users planning heavier sustained workloads on a budget-friendly flash NAS.

Below is a summary table of the Xyber Hydra’s tested performance metrics:

Xyber Hydra NAS Review – Internal Hardware

At the heart of the Xyber Hydra N150 NAS is the Intel Twin Lake N150 processor, a 4-core, 4-thread CPU with a base TDP of 6W and burst frequency up to 3.6GHz. This is the same CPU found in the GMKtec G9, offering modest but sufficient processing power for lightweight NAS duties, such as file serving, 4K media playback, and hosting a handful of Docker containers or virtual machines. The Hydra’s choice to stick with the N150 over more power-hungry options like the N355 reflects a deliberate balance between thermals, noise, and power efficiency in such a confined chassis.

The CPU is passively cooled through the same baseplate and active fans that handle SSD thermals, and testing showed it remained below 60°C even during full-load stress tests when fans were set to automatic. When set to maximum in BIOS, the CPU temperature remained even lower, consistently in the mid-40°C range, indicating that the thermal headroom of this setup is acceptable for the N150’s intended use cases. While the CPU is not equipped with QuickSync hardware transcoding found in Intel’s higher-end processors, it did demonstrate capable software transcoding during single-stream 4K Plex playback without pushing the CPU beyond 80% utilization.

One area where the Hydra stands apart slightly from its competitors is its memory configuration. Instead of the 12GB soldered LPDDR5 memory seen in the G9, the Hydra comes pre-equipped with 16GB LPDDR5 memory, also soldered directly to the board and therefore not user-upgradable. This extra 4GB provides additional breathing room for multi-tasking, running memory-intensive services, or hosting larger numbers of containers without encountering swap usage under typical loads. The memory is clocked at 4800MHz and, as expected at this price point, is non-ECC. Given the system’s target market and workload scenarios, this is a reasonable trade-off — ECC memory would nearly double the cost of the system for relatively little gain in this context. The fixed nature of the memory remains a limitation for power users but ensures predictable thermal and power behavior that a socketed SO-DIMM might not allow in such a tightly-engineered package.

Hydra’s internal hardware is clearly aimed at delivering solid performance for home and small-office NAS duties while maintaining a low noise profile and power envelope. While it is not designed for demanding enterprise workloads or highly parallelized tasks, it offers a balanced set of capabilities appropriate to its price and physical footprint.

Xyber Hydra NAS Review – Ports and Connections

The Xyber Hydra N150 NAS offers a fairly comprehensive array of ports and connectivity options, matching its closest competitor, the GMKtec G9, almost identically. On the rear panel, the system is equipped with two Intel i226-V 2.5GbE RJ45 ports, which support link aggregation and failover. These provide a theoretical combined throughput of up to 550–580 MB/s when paired with appropriately configured switches.

While some users may be disappointed by the absence of 10GbE, this is an understandable compromise given the limitations of the N150 CPU’s PCIe lane budget and the heat constraints of such a compact design. As noted during testing, users can reclaim one of the M.2 slots to install a PCIe-to-10GbE adapter, though this does come at the cost of one storage bay.

The networking implementation also includes support for wake-on-LAN (WoL) and PXE boot functionality, adding flexibility for remote management and deployment scenarios. The system also integrates an M.2 Wi-Fi 6 module with dual antenna outputs. This enables wireless network support, now even compatible with UnRAID as of recent updates, and can serve as either a primary or fallback network connection in environments where cabling is not practical.

In terms of USB connectivity, the Hydra provides a total of four ports: three USB 3.2 Gen 2 Type-A ports located on the rear panel, and one USB-C port that is also used for power delivery. The three USB-A ports deliver up to 10Gbps each, which is sufficient for attaching external backup drives, additional storage enclosures, or other peripherals such as a UPS monitoring interface. The USB-C power connector is fed by an external wall-mounted 48W integrated external power brick, which means users cannot simply swap in any generic USB-C charger — it is a dedicated high-wattage supply.

This design choice ensures sufficient and stable power delivery to all internal components even under peak load, but it does limit flexibility somewhat compared to true USB-PD-compatible implementations. Users looking to attach keyboards, mice, or other USB peripherals directly to the system will find that the port count is adequate, though not expansive.

For video output, the Hydra offers two HDMI 2.0 ports, supporting up to 4K resolution at 60Hz. These are useful for initial OS installation or configuration, as well as for users who intend to repurpose the NAS as a hybrid media player or thin client. During testing, the HDMI output worked without issue on both the preinstalled Ubuntu OS and when booting into alternative operating systems. While video output is rarely essential for a headless NAS, its inclusion enhances usability, especially for less experienced users or those deploying the system in multi-role environments. Combined with the USB ports and network interfaces, the Hydra provides a balanced set of I/O suitable for its intended use cases, with enough bandwidth to fully utilize its internal storage under typical workloads.

Below is a summary table of the ports and connections on the Xyber Hydra:

Xyber Hydra NAS Review – Conclusion and Verdict

The Xyber Hydra N150 NAS represents a deliberate and measured evolution of the budget-friendly compact NAS formula, clearly designed to resolve key weaknesses of similar products like the GMKTec G9 without altering the fundamental architecture. Its use of a thicker, thermally conductive metal base plate provides demonstrable improvement in heat dissipation compared to the plastic underside of the G9, a difference borne out in extended load testing where temperatures stabilized more quickly and stayed lower when fan profiles were adjusted. The pre-installed 64GB eMMC module running Ubuntu out of the box eliminates the initial configuration barrier often faced by novice users, while still allowing more experienced users to easily replace it with their OS of choice, such as ZimaOS or TrueNAS. The inclusion of a 512GB NVMe SSD in the primary M.2 bay adds immediate storage capacity without requiring an upfront investment in additional drives, an uncommon but practical feature at this price point.

Internally, the decision to provide 16GB of fixed LPDDR5 memory — 4GB more than its nearest comparable competitor — gives the Hydra slightly more headroom for memory-intensive tasks, such as running lightweight container workloads or maintaining a larger metadata cache for media streaming applications. While the memory remains non-upgradable, the choice of capacity is a reasonable compromise given the constraints of the Intel N150 platform and the system’s focus on cost efficiency. The integrated Wi-Fi 6 module, with dual antennas and full UnRAID compatibility, is another meaningful addition, enabling wireless deployments where cabling is impractical and expanding the deployment scenarios for home and small office users. These subtle but important upgrades make the Hydra feel more complete out of the box, catering to a broader range of use cases with fewer compromises.

That said, the Hydra still shares many of the inherent trade-offs of its class. The N150 processor is adequate for modest workloads, but becomes saturated under sustained high parallel usage, especially when all four M.2 slots are simultaneously active and the CPU nears 100% utilization. The PCIe lane limitations of the platform, with each M.2 slot limited to Gen3 x2 speeds, restrict the aggregate performance potential of RAID arrays or concurrent high-bandwidth operations. Similarly, the continued reliance on dual 2.5GbE ports limits maximum external throughput despite the internal SSD bandwidth being capable of more, and although M.2-to-10GbE adapters remain an option, they come at the cost of sacrificing one storage slot. BIOS-level adjustments are also required to extract the best thermal and fan performance under heavy use, something that more advanced users will appreciate but could frustrate beginners.

Overall, at its introductory price of $218.99, the Xyber Hydra N150 achieves a strong balance of value, practicality, and refinement in the entry-level NAS segment. The thoughtful inclusion of extras — the 64GB bootable eMMC, 512GB SSD, improved cooling, and additional memory — make it feel more turnkey than competing models, while still leaving room for advanced customization. It’s a sensible option for users seeking a compact and efficient NAS for personal cloud storage, light virtualization, or as a dedicated media server, provided expectations around CPU and networking throughput are kept realistic. For its target audience, the Hydra is a compelling and notably improved choice that addresses many of the criticisms of earlier designs without abandoning the affordability that defines this class of devices.

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 CWWK N355 features a robust industrial design, with an all-metal chassis that acts as a heat sink, efficiently dissipating heat from critical components. The exterior is entirely metal, including the base panel, which features mesh ventilation to enhance airflow. A top-mounted active cooling fan ensures consistent airflow across the CPU and networking components, preventing thermal throttling under sustained workloads.

Internally, copper heat plates are placed over the CPU and 10GbE controllers, allowing for direct heat transfer to the chassis. This cooling system is highly effective, maintaining temperatures within safe limits even under heavy network and storage loads. During testing, the device remained at an average of 50-55°C under full load, with the fan producing minimal noise.

The cooling implementation makes the CWWK N355 a viable option for extended use in high-performance NAS, virtualization, or firewall applications where thermal efficiency is crucial. Given its mix of powerful networking features, ample connectivity, and storage options, this device has the potential to serve a broader range of applications than just routing. However, evaluating its strengths and weaknesses is crucial before repurposing it for a NAS setup.

One of the standout features of the CWWK N355 is its impressive network connectivity. Equipped with dual 10GbE SFP+ ports and two 2.5GbE i226V LAN ports, it offers significantly more bandwidth than traditional consumer NAS devices.

These high-speed connections enable rapid file transfers, efficient virtualization networking, and multi-user simultaneous access without bottlenecks.

It also includes two M.2 NVMe slots and a SATA 3.0 port, making it highly flexible for storage configurations. This means users can integrate fast NVMe storage while still having the option to include traditional SATA drives for cost-effective capacity expansion.

The aluminum chassis with active cooling enhances its thermal efficiency, ensuring stable operation even under load, a crucial aspect for maintaining performance in continuous 24/7 operation.

The N355 CPU, an Alder Lake-N processor, brings 8 cores and 8 threads, with a base clock of 1.8GHz and a boost up to 3.8GHz. This processor is designed for efficiency while maintaining a respectable level of performance for various workloads.

It also features integrated Intel UHD graphics, which allows it to handle lightweight GPU tasks such as video decoding, remote desktop applications, and low-power graphical processing.

The DDR5 SO-DIMM slot supports up to 48GB RAM, although some listings mention 32GB as the maximum. This expanded memory capacity is particularly beneficial for virtualization, allowing users to run multiple lightweight VMs, containers, and even a Plex media server with modest hardware-accelerated transcoding capabilities.

The combination of efficient CPU performance and expandable RAM makes it versatile, but users should be aware of its limitations when handling resource-intensive applications.

However, storage expansion comes with some challenges. While the device technically supports two M.2 NVMe drives, only one slot is a standard 2280 interface. The second slot requires an adapter, which is included, but adds complexity to installation. This additional requirement may be a concern for users who are less experienced with hardware modifications or prefer simpler plug-and-play configurations.

The SATA drive support is somewhat limited—while the port is available, there is no dedicated internal space for mounting a 2.5-inch drive inside the enclosure, meaning external mounting is necessary. This lack of internal SATA mounting may be a dealbreaker for those who prefer a more integrated and clutter-free build. While external enclosures or adapters could be used to house SATA drives, it introduces additional complexity and potential cable management issues.

Power consumption is another area of concern. Under idle conditions, the device draws 21-22W, which is quite high compared to traditional NAS appliances. Many consumer NAS systems are designed to run efficiently at around 10W to 15W when idle, making this unit significantly more power-hungry when not under load.

Under load, with 10GbE connections active, VMs running, and storage drives in use, power consumption reaches 36W. While this is still within reasonable limits for a device offering high-speed networking and multi-core processing, it is something to consider for users prioritizing energy efficiency. Over time, the additional power draw may add up, especially for those running multiple devices in a home or small business setup. If power efficiency is a critical factor, other lower-power options might be preferable.

Performance-wise, the M.2 NVMe drives achieve read speeds of up to 720MB/s and write speeds of 690MB/s.

While SATA performance peaks at around 200MB/s with a standard HDD. These speeds are respectable but fall short of fully utilizing the available 10GbE networking potential.

While this is acceptable for most home NAS applications, the 82599ES 10GbE controller is a notable bottleneck. It is an older PCIe Gen2 x4-based controller (in this deployment at least), which limits full 10GbE speeds.

In testing, even with dual 10GbE connections active, network transfers maxed out at around 600-700Mbps per link, rather than saturating the full 10GbE bandwidth on each of them.

This suggests that while it is capable of handling high-speed transfers, it is not the ideal choice for users who need to maximize 10GbE connectivity for large-scale data transfers or enterprise workloads.

While the CWWK N355 offers excellent networking and processing power, its relatively aging 10GbE controller, high idle power consumption, and limited internal storage space make it less ideal for an all-purpose NAS. However, it excels as a high-performance firewall/router, Proxmox host, or Plex server for users who can work around these limitations.

Users interested in setting up an advanced home lab or small business server might find this device appealing due to its networking flexibility, processing capability, and virtualization potential. While it lacks native software optimization found in dedicated NAS brands, those comfortable with manual setup and open-source NAS software will find it a capable and adaptable device.

For those seeking a dedicated NAS solution with full 10GbE performance, an ITX motherboard with PCIe 3.0 slots and dedicated storage expansion might be a better alternative. Such options would provide greater flexibility for storage expansion, more efficient networking solutions, and overall better optimization for NAS workloads. But if you’re looking for a compact, all-in-one networking and storage device, the CWWK N355 is an impressive contender.

Just be mindful of the legacy components and potential bottlenecks before making your final decision. With the right configuration and expectations, it can serve as a cost-effective and powerful addition to a home lab or small business network setup.

Synology (FINALLY) has an NVMe Flash Server – The Synology PAS7700 System

Synology are seemingly going ‘all guns blazing’ at Computex 2025 this year, with a wide array of hardware and software solutions being revealed at the event. Many of these we already know about via official and unofficial reveals over the last 6 months or so, how the PAS NVMe flash storage system is one that was actually originally shown last year at the brand’s 2024 Solution Exhibition in Taipei, this was still an early prototype system and was built using an existing 2U chassis and was much more comparable to existing SAS storage systems from the brand. However, the PAS NVMe Flash system has seemingly (and RAPIDLY) evolved since it was first revealed as an early 12 bay prototype 2U rackmount last year into a dual active 4U Behemoth solution that is significantly more focused on leveraging the performance benefits of NVMe, alongside the scale-out, redundancy and failover of other enterprise tier Synology NAS solutions.

Synology already has an existing range of SSD Flash soltuons, in their Flashstation series, but this proposed PAS7700 system is a completely different class of system against those more classic DSM hardware systems. Synology has been somewhat behind the curve when it comes to NVMe flash systems in the last few years (both entry class m.2 NVMe systems at desktop, but also larger business and enterprise class NVMe over U.2/U.3 compared with competitors such as QNAP (and their FX/FU series), but the PAS is hoping to fill this gap in the brand’s portfolio at this higher tier of buyer. So, what do we know so far?

Synology PAS7700 Hardware Specifications

The Synology PAS7700 is a 4U rackmount dual-node NVMe flash storage system engineered for high-performance, mission-critical enterprise workloads. Designed with a non-disruptive architecture, it enables active-active operations across both nodes, ensuring continuous data availability and efficient load distribution without single points of failure. Each node occupies 2U of rack space and operates independently, yet cooperatively, allowing both to concurrently handle client requests and internal processes. This design eliminates the need for manual failover while maintaining performance even during node maintenance or partial outages.

At the heart of each node lies a 24-core AMD EPYC processor, optimized for dense, multi-threaded workloads such as data analytics, database transactions, and large-scale virtualization. These processors provide ample PCIe Gen4 lanes to support high-speed interconnects, storage interfaces, and compute operations. Each node is equipped with 64GB of DDR4 ECC memory out of the box, with upgrade support up to 1TB. This high memory ceiling is particularly beneficial for large-scale caching, deduplication, and inline compression tasks in high IOPS environments. Memory cache protection mechanisms are built in to preserve data integrity during unexpected power loss, using supercapacitors or battery-backed modules.

The storage backplane supports a total of 48 U.2 or U.3 NVMe SSDs across the chassis—24 per node—maximizing both performance and density. Drive control is split between the native AMD EPYC-integrated PCIe controllers and additional PCIe switching and management provided by ASMedia Technologies, likely to balance performance across multiple backplanes and mitigate PCIe bottlenecks. This configuration ensures that each SSD can be utilized to its full potential with minimal latency and optimal throughput. Network connectivity includes a dedicated 1GbE copper port per node for management, along with dual 10GbE NICs for data operations. These ports support link aggregation and failover, with options for expansion to higher-speed interfaces expected, though not yet confirmed. The PAS7700 likely supports several PCIe expansion slots internally, allowing future upgrade paths to 25/40/100GbE if required. This flexibility positions the unit for use in diverse network topologies and high-bandwidth enterprise infrastructures.

That said, we should discuss the thorny subject of storage media. Synology has recently implemented a more stringent hardware compatibility policy, mandating the use of Synology-branded or certified storage media in its latest 2025 Plus Series NAS devices. This policy restricts full functionality and support to only those drives that have been validated by Synology, potentially limiting user flexibility and increasing costs due to reduced third-party options. Currently, Synology’s in-house SSD lineup includes SATA SSDs and M.2 NVMe SSDs, with capacities up to 800GB. This raises questions about their plans for higher-performance storage media suitable for systems like the PAS7700, which is designed for demanding enterprise workloads. As of now, Synology has not announced any U.2 or U.3 NVMe SSDs in their product range. Given the PAS7700’s reliance on high-speed NVMe storage, it’s unclear whether Synology will expand its SSD offerings to include higher-capacity and performance options or if they will certify third-party drives for use with this system. The company’s updated compatibility lists will be crucial for users to identify approved drives. Until more information is available, potential PAS7700 users may need to consider the implications of Synology’s hardware compatibility policies on their storage choices.

Synology PAS7700 Services and Flash Protocols

The Synology PAS7700 supports a diverse array of storage access protocols optimized for NVMe over Fabrics (NVMe-oF), ensuring compatibility with modern data center architectures and latency-sensitive applications. These protocols are tailored to support high-throughput and low-latency workloads across both local and remote environments, catering to sectors such as virtualized infrastructure, high-performance computing, and real-time analytics.

Among the supported technologies are NFS RDMA, NVMe-TCP, NVMe over Fibre Channel (NVMe-FC), and NVMe over RoCE (Remote Direct Memory Access over Converged Ethernet). These protocols differ in terms of performance characteristics, implementation complexity, and deployment environments, giving administrators flexibility in aligning the system’s networking stack with existing infrastructure and performance objectives. These include:

• NFS RDMA (Remote Direct Memory Access):

  • Enhances traditional NFS performance by bypassing the CPU for memory transfers.

  • Significantly reduces latency and CPU usage in environments using NFSv4.x.

  • Ideal for high-performance, low-latency use cases like virtual machines or scientific computing.

• NVMe-TCP (NVMe over TCP/IP):

  • Extends NVMe-oF across standard Ethernet networks without requiring specialized hardware.

  • Enables NVMe-level performance benefits using existing TCP infrastructure.

  • Easier to deploy in enterprise environments with mixed networking equipment.

• NVMe-FC (NVMe over Fibre Channel):

  • Combines the speed of NVMe with the reliability of Fibre Channel.

  • Suitable for enterprises already using Fibre Channel SANs.

  • Offers low-latency performance with high stability and established zoning capabilities.

• NVMe/RoCE (RDMA over Converged Ethernet):

  • Provides near-direct memory access over Ethernet without involving the CPU.

  • Achieves ultra-low latency for applications such as real-time trading or video rendering.

  • Requires a compatible network fabric with lossless Ethernet configuration.

We are still awaiting confirmation on whether this will be running on traditional DSM, a dual controller variation (such as found on the current UC3200 0 Active/Active system), a multinode management variation (as found in the GS/GridStation system, or a brand new splinter of DSM services (as found in the DP series with Active Protect).

Synology PAS7700 Failover and Redundancy

The Synology PAS7700 is designed with full-stack redundancy to eliminate single points of failure and minimize service disruption across hardware, software, and protocol layers. Its dual-node active-active design enables uninterrupted operations even during firmware updates, system maintenance, or unplanned hardware failures. This architecture ensures that both nodes can operate independently while maintaining synchronized data access and state, effectively enabling non-disruptive service continuity in multi-user enterprise environments. Each layer of the system—from networking to storage to memory—is fortified with specific failover mechanisms. Networking is protected via IP failover configurations, allowing services to automatically reroute through a secondary interface or node should a primary link fail. The system also supports Multipath I/O (MPIO) across iSCSI, Fibre Channel, and NVMe-oF protocols, ensuring high availability and load balancing across multiple paths. On the protocol level, persistent handle support in SMB and grace periods in NFS ensure that client sessions remain intact during failovers or server transitions.

Synology further implements failover at the component and data protection level. Memory modules are equipped with cache protection to safeguard in-flight data in the event of power loss, typically via battery backup or capacitor-based retention systems. On the storage layer, support for RAID-TP (triple parity) adds an extra layer of disk fault tolerance, protecting against up to three simultaneous drive failures. Additionally, enterprise-grade SSDs used in the PAS7700 are expected to include power loss protection (PLP), preserving cached writes during sudden shutdowns.

• Protocols:

  • SMB Persistent Handles: Maintains client file handles during failover events.

  • NFS Grace Periods: Allows NFS clients to re-establish sessions without data loss.

  • MPIO: Multipath I/O for load balancing and failover across multiple transport paths.

• Networking:

  • IP Failover: Automatically reroutes network services to a standby node or NIC if a primary fails.

• System-Level:

  • Hardware Failover: One node takes over if the other becomes non-functional.

  • Upgrade Failover: Supports live system or firmware updates without downtime.

• Memory:

  • Cache Protection: Retains volatile memory contents in the event of power loss using supercaps or batteries.

• Storage:

  • RAID-TP: Triple parity RAID support for enhanced data redundancy.

  • Power Loss Protection (PLP): SSDs preserve unwritten data during power failure.

Whether other specific SSD/Flash services that are currently available on devices like the Flashstation series (such as RAID F1 for controlled and predicted NAND wearing) will also be integrated here on scale are yet to be confirmed. While the full software environment and feature set of the Synology PAS7700 are yet to be confirmed, its hardware architecture and protocol support position it as a serious entry into the enterprise flash storage segment. With dual-node active-active operation, extensive NVMe protocol compatibility, and comprehensive failover mechanisms, the PAS7700 is clearly designed for organizations that require uncompromising uptime and performance. As more details emerge at Computex 2025, the PAS7700 is expected to clarify its role within Synology’s broader storage portfolio—particularly how it compares to the UC series and where it fits in demanding environments such as virtualized infrastructure, high-frequency transactional workloads, and critical business continuity deployments.
