Xyber Hydra N150 NAS Review – Better than the GMKtec G9?
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:
Test Scenario | Result / Observation |
---|---|
Single SSD Read (Bay 1) | 1.4–1.5 GB/s |
Single SSD Write (Bay 1) | ~1.1 GB/s |
Dual SSD Transfer | 720–730 MB/s |
Quad SSD Sustained Write | 900 MB/s–1 GB/s per drive (CPU-limited) |
Idle Power Draw | 15.6–15.7 W |
Full Load Power Draw | 26–27 W |
Idle Noise | 30–32 dBA |
Full Fan Noise | 37–38 dBA |
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.
Component | Specification |
---|---|
Processor (SoC) | Intel Twin Lake N150, 4 cores / 4 threads, 3.6GHz burst, 6W TDP |
Memory | 16GB LPDDR5 (4800MHz, soldered, non-upgradable) |
eMMC Storage | 64GB onboard, preloaded with Ubuntu OS |
NVMe Slots | 4x M.2 2280 NVMe (PCIe 3.0 x2 per slot) |
Cooling | Passive aluminum baseplate with thermal pads + dual active fans |
Thermals (CPU) | ~45–60°C under load depending on fan settings |

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:
Port / Interface | Specification |
---|---|
Ethernet | 2x 2.5GbE RJ45 (Intel i226-V, link aggregation) |
Wi-Fi | Wi-Fi 6 (via M.2 module, dual antennas included) |
USB-A Ports | 3x USB 3.2 Gen 2 (10Gbps) |
USB-C Power Input | 1x USB-C (requires bundled 65W power adapter) |
HDMI Outputs | 2x HDMI 2.0 (4K @ 60Hz) |
Wake-on-LAN | Supported |
PXE Boot | Supported |
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.
