Is the Sipeed NanoKVM Safe? On-board Microphone Identified

The Sipeed NanoKVM Cube is a low cost, network connected KVM built around the LicheeRV Nano RISC-V module, and recent reporting has drawn attention to the fact that this first generation hardware quietly inherited an onboard analog microphone from that core board. While the LicheeRV Nano documentation clearly lists audio input and output capabilities, the NanoKVM product materials initially focused on its KVM role and did not prominently call out the presence of a microphone on the internal PCB. That gap in presentation, combined with the device’s origin in China and its role as an always-on, remotely accessible appliance, has led to questions about transparency and potential privacy impact. This article reviews what is actually on the hardware, how Sipeed has responded, which issues have been addressed in software, and what residual risk remains for users who already have the NanoKVM Cube deployed.

The NanoKVM Cube and That Microphone – What We Learned?

The initial detailed public discussion of the NanoKVM Cube microphone came from a Telefoncek.si research article, which documented security testing of early units and highlighted the presence of a small, operational microphone on the device’s PCB. The NanoKVM Cube is built on the LicheeRV Nano platform, and that design decision is the origin of the audio hardware. The LicheeRV Nano specification explicitly lists an onboard analog silicon microphone for audio input and a PA amplifier for driving a small speaker, because the module is intended as a general purpose SBC for a range of embedded applications. When Sipeed used this module as the core of a consumer facing KVM, the Cube inherited that audio circuitry intact, including the tiny surface mount MEMS microphone, even though typical KVM usage does not require audio capture capabilities.

What Telefoncek.si article from Feb ’25  drew attention to was the combination of this hardware and a software stack that already contained working audio tooling. Researchers who obtained early NanoKVM units found that, with SSH access, standard ALSA tools such as amixer and arecord could be used to adjust gain and record ambient sound through the built in microphone, and that the resulting audio files could be copied or potentially streamed off the device. At that time, the NanoKVM product page described its relationship to the LicheeRV Nano SDK and resources in general terms, but did not highlight that a functioning microphone remained present on the KVM board. For many users, that gap between what the SBC documentation said and what the KVM product page emphasized was perceived as a lack of clear disclosure rather than a predictable consequence of module reuse.

The NanoKVM Security Concern and Presentation Issues

The initial concern around NanoKVM security was not limited to the microphone. Early firmware builds shipped with default credentials, SSH enabled, weak web security controls, and hardcoded encryption keys that were identical across devices. Researchers also found diagnostic and security utilities present on the system image that were more appropriate for development or lab use than for a small appliance likely to be exposed on home or small business networks. These findings created a picture of a product that had been moved from prototype to retail relatively quickly, with baseline functionality in place but limited attention paid to hardening or least privilege.

Presentation played a significant role in how the microphone issue was perceived. For the LicheeRV Nano SBC, the presence of audio input and output is clearly listed as part of the hardware specification, and that makes sense for a general purpose module. For NanoKVM Cube, the public facing documentation initially focused on KVM features, HDMI input, and compatibility with the LicheeRV Nano SDK, while leaving the inherited audio hardware implicit. Only later did the NanoKVM wiki entry gain explicit wording that the Cube retains display, touch, microphone, and amplifier circuits from the base module, and that newer firmware versions would remove the relevant drivers and future production runs would omit these components entirely.

Sipeed’s public responses combine these two aspects. On the one hand they point to the LicheeRV Nano documentation and the updated NanoKVM wiki as evidence that the microphone is not intended to be secret. On the other hand they argue that, from a threat model perspective, the presence of a board level microphone does not materially change risk once an attacker has obtained full control of the device, since they could already perform sensitive actions through the host system. For critics, the issue is less about the technical possibility of audio capture in a fully compromised scenario and more about expectation and trust: a network attached KVM marketed primarily on its remote control capabilities but not clearly calling out built in audio capture hardware is likely to be treated with more suspicion, especially when it comes from a vendor that has already needed several rounds of security fixes.

Reality Check – How Much of a Concern is this?

From a strict security engineering viewpoint, the onboard microphone in the NanoKVM Cube does not create a new, independent way into the device. An attacker still needs a working exploit, exposed service, or misconfiguration to gain sufficient access before any audio capture is possible. In that sense, the primary risk is still the usual set of issues that apply to any IP KVM: exposed management interfaces, weak credentials, unpatched firmware, or poor network segmentation. If those fundamentals are handled correctly, the probability that a remote attacker can turn the Cube into a listening device is significantly reduced, and using alternative firmware or a locked down software stack can further narrow the options.

The impact side of the equation is different. Once a NanoKVM Cube is compromised at a system level, the presence of a functional microphone increases the potential harm compared with a KVM that only relays keyboard, video, and mouse. A device that sits in a home office, lab, or equipment room and can capture ambient sound can turn a general compromise into a privacy incident that extends beyond the connected host system. For some users that incremental risk will be acceptable if the device is strictly isolated, regularly updated, and treated as an untrusted appliance at the edge of the network. For others, the residual possibility of room audio capture from a small, unattended box may be enough to justify either physical removal of the mic, replacement with a later hardware revision, or avoiding this particular model altogether.

Note. Here is the board view of the NanoKVM USB and NanaKVM Pro PCIe, with no microphone visible:

Asking Sipeed Questions about the NanoKVM Microphone Issue – How and Why This Occurred?

To clarify how the microphone ended up in a shipping KVM product and what Sipeed intends to do about it, I put a series of written questions to the company. The goal was not to reassess the technical findings already covered by independent research, but to obtain clear statements from the vendor on 4 points: how they view the documentation and disclosure around the microphone, which specific NanoKVM variants and hardware revisions include it, what mitigations they believe limit its security and privacy impact for existing deployments, and what concrete changes they are planning for future production runs. The questions and Sipeed’s responses are reproduced in full below. Thanks again to Caesar Wu for his time in answering my questions.

Why was there a microphone on the device, and how/why it’s absent from the documentation?

This premise contains a serious factual error made by the original article. The presence and rationale for the microphone are not undocumented; they are explicitly mentioned on the product’s main Wiki page: https://wiki.sipeed.com/hardware/en/kvm/NanoKVM/introduction.html#NanoKVM

Which Version/Batch/Revisions of NanoKVM feature this Microphone?

The microphone is featured on the NanoKVM Lite and NanoKVM Cube versions. These are derivative products based on the LicheeRV-Nano (RISC-V SBC core module) and consequently inherited its Single Board Computer (SBC) peripherals, including the microphone, speaker, and MIPI touchscreen support.

Is this present on other versions of NanoKVM (i.e PCIe, Pro, USB, etc)?

No. Other products use custom-designed boards dedicated solely to the KVM scenario. They do not reuse the SBC module and therefore do not include non-KVM-essential components.

Why was this microphone not eliminated at the point of production?

The core part of NanoKVM-Cube/Lite is LicheeRV Nano. We reuse LicheeRV Nano as a standard “SOM” in many different products, like AI Camera MaixCAM:    https://www.aliexpress.com/item/1005006912917562.html . And our toB customer also use it as a standard linux core board(Just like RPi CM4, CM5), they are very satisfied with the onboard microphone, speaker, and touch screen.  As stated in my previous email, we maintain that logically, the retention of the microphone on the board does not introduce any negative impact on security. While the onboard components (microphone, speaker power amplifier (PA), and touchscreen connector) introduce a slight increase in Bill of Materials (BoM) cost, this decision significantly simplifies inventory management.

In fact, the base LicheeRV Nano product already comes in 4 configuration variants (Basic, Eth, WiFi, and Ethe+WiFi).  If we were to further segment the inventory by adding options for the presence or absence of the microphone and touchscreen connector, the total number of SKUs  would increase exponentially(the number of SKUs multiplies by two for every added configuration options). Therefore, based on a comprehensive consideration of security, cost efficiency, and inventory management complexity, we maintain the microphone, speaker PA, and touchscreen connector as the default base configuration.

What steps are being taken to ensure that this does not pose a Security/Privacy threat to user who have the nanoKVM in active deployment?

Users must understand the threat model: an attacker can only listen via the onboard mic if the NanoKVM itself has already been fully compromised. The paradox is that once compromised, the attacker already has sufficient privileges to perform high-level operations (include record audio via PC’s own mic). Therefore, the presence of the onboard mic does not increase the inherent security risk of the device. We emphasize that proper network risk awareness and isolation configuration by the user are essential, regardless of whether the device is a NanoKVM, JetKVM, GL.iNet KVM, or PiKVM.

What further steps have been made/planned at Production to avoid this occurring again in future hardware releases?

As stated in Question 4, we plan to remove the microphone in the next batch of the Lite/Cube models purely for psychological comfort and ease of mind for our users. We acknowledge this step will inevitably increase our inventory management complexity due to the need for separate SKUs and production processes. We are also implementing more rigorous hardware audits to ensure compliance with the Principle of Least Privilege in future designs.

Conclusion – Should NanoKVM Owners Be Worried?

For current NanoKVM Cube owners, the level of concern depends largely on how and where the device is deployed. In a well segmented environment where the KVM sits on an isolated management network, with updated firmware and strong access controls, the presence of a dormant microphone on the board is a secondary issue behind the more general risk of any remote management appliance. In small or less structured setups where the NanoKVM has direct exposure to the internet or shares a LAN with everyday client devices, both the historical software weaknesses and the possibility of audio capture in a successful compromise are more relevant factors in deciding whether to keep using the unit unchanged.

Looking ahead, Sipeed has stated that newer firmware removes the audio drivers and that future Lite and Cube batches will omit the microphone and related circuitry entirely, which addresses the concern for new buyers over time. For existing devices, users who are uncomfortable with any residual audio capability have practical options: physically removing or disabling the mic at board level, reflashing with a minimal or community maintained software stack, or replacing the hardware with a later revision or a different KVM platform. The key is to treat the NanoKVM Cube as a high impact management tool rather than a neutral accessory, and to decide whether its cost and feature set justify the additional precautions it requires in a given environment.

New KVMs, Travel Routers and WiFi 7 Tech on the way from Gl.iNet Soon

Gl.iNet is preparing several new devices for late 2025 and early 2026 that expand its presence in mobile networking, remote access management, and high speed home routing. These include the Beryl 7 travel router, the Comet 5G RedCap KVM with an integrated WiFi access point, and the Flint 3e dual band WiFi 7 desktop router. Each system is positioned to address a specific operational requirement, ranging from portable VPN-enabled wireless access to remotely deployable KVM control and multi gigabit home connectivity. The updated lineup also includes the Brume 3 high speed VPN security gateway, which builds on the Brume 2 by adding faster encrypted throughput and broader support for open VPN standards such as AmneziaVPN. Collectively, these releases indicate that Gl.iNet is prioritising more capable processors, improved wireless performance, and tighter integration between VPN features and local network tools.

Beryl 7 Travel Router (GL-MT3600BE)

The Beryl 7 is positioned as an updated travel router that builds on the feature set of the original Beryl while shifting to a more capable Qualcomm quad core processor running at 1.1GHz and 256MB of DDR4 memory. It uses IEEE 802.11a, b, g, n, ac, ax and be wireless standards and supports dual band WiFi 7 operation on the 2.4GHz and 5GHz bands. Although it does not include 6GHz support, it delivers higher throughput than its predecessor, reaching 688Mbps on 2.4GHz and 2882Mbps on 5GHz. The unit also integrates two foldable external antennas and two 2.5GbE ports that can be configured as WAN plus LAN or as dual LAN for specific on-the-go deployment requirements.

The system maintains the travel-focused design of the original model by keeping compact dimensions, low power requirements and USB-C power delivery suitable for laptops, power banks and small chargers. The physical toggle switch remains, allowing quick selection between standard routing and VPN operation without navigating menus. VPN capability is supported by OpenVPN DCO, WireGuard and AmneziaVPN, enabling users to run a VPN server at home and connect to it through the Beryl 7 when travelling. As noted during the demonstration, the WiFi 7 implementation prioritises improved packet handling and multi-link operation rather than wide-band 6GHz performance, which keeps the device compatible in regions where 6GHz availability is limited or restricted.

The Beryl 7 aims to retain pricing similar to the original Beryl while scaling both its internal hardware and wireless capabilities. It uses a gigabit-class Ethernet configuration, supports sub-18W peak power draw and retains a form factor suited for hotel WiFi, temporary offices and public hotspot environments. The inclusion of 2.5GbE, higher throughput on both bands and broader VPN support allows it to operate as a compact edge router for users needing reliable encrypted access across multiple devices. Despite carrying a WiFi 7 label, it does not support the 6GHz band, mirroring the Slate 7, and instead focuses on maximising performance within the 2.4GHz and 5GHz ranges. Nevertheless, this is going to be a disappointment to users who were hoping to see ‘full fat’ WiFi 7 with that 3rd frequency in play, and really maximize MLO use.

Comet 5G KVM with Redcap 5G SIM/LTE Support (GL-RM10RC)

The Comet 5G is a RedCap-based KVM device that integrates remote management, HDMI capture and mobile connectivity into a single compact unit. It uses a quad core ARM Cortex-A53 processor, 1GB of DDR3 memory and 64GB of eMMC storage, matching the hardware profile of the existing Comet Pro. The device includes both HDMI in and HDMI out, allowing it to be used for remote console access, system monitoring and basic pass-through scenarios. A 2.22-inch touchscreen provides local visual feedback including IP address, active WiFi status and connection indicators. Wireless capability is delivered through 802.11a/n/ac/ax at 150Mbps on 2.4GHz and 286Mbps on 5GHz, supported by an external dual band WiFi 6 antenna rather than a WiFi 7 module.

A key addition to this model is the integrated 5G RedCap SIM slot. This allows the device to operate independently of the local network when deployed on-site, which is relevant for administrators or engineers who need to access remote systems without relying on customer-provided WiFi or Ethernet. The mobile connection also supports failover for situations where the primary network becomes unavailable, ensuring that remote KVM access remains possible. During the demonstration, it was highlighted that this improves usability for workloads such as multi-day monitoring or configuration tasks performed in locations where network restrictions or firewall rules prevent direct access.

The Comet 5G retains a familiar selection of ports including USB-C for power, USB-A for peripherals, a gigabit Ethernet port for direct LAN connection and a SIM slot for mobile data. The device is not PoE-powered, although an injector or adapter is expected to be offered as an accessory. This approach keeps the unit closer in design to a travel-friendly tool rather than a fixed enterprise appliance. It remains suited to users who already deploy compact KVM units as part of their field equipment and who require a method of accessing remote devices through either wired, wireless or cellular links.

The combination of 5G failover and HDMI-based remote access positions it as a small-scale management device for distributed environments, temporary field sites or systems that require out-of-band connectivity. Many users will make comparisons between this and the recently crowdfunded ‘Comet Pro’ device (very similar, but alongside a few small changes internally and adjustable antennae, also does not support a 5G SIM CARD/LTE), as well as the Comet PoE device recently released. This is largely the same, but tailored towards a different, decidedly more mobile deployment.

Flint 3e Dual Band WiFi 7 Router (GL-BE5600)

The Flint 3e is a dual band WiFi 7 router aimed at users who want higher wireless throughput and multi gigabit Ethernet connectivity without moving to a full tri band system. It is built around a Qualcomm quad core processor running at 1.5GHz with 1GB of DDR4 memory and 512MB of NAND storage. Wireless support covers IEEE 802.11a, b, g, n, ac, ax and be, delivering 688Mbps on 2.4GHz and 5764Mbps on 5GHz. The unit includes four external foldable antennas, a dual colour LED indicator and a housing designed for stable operation in home or small office environments. Connectivity is centred around five 2.5GbE ports, with one operating as a dedicated WAN input and the remainder configurable as LAN. This gives the router a faster wired backbone than earlier consumer models from the brand.

The router maintains a focus on local performance and low latency operation rather than offering the widest possible spectrum support. It does not include 6GHz capability, placing it closer to the Beryl 7 and Slate 7 in terms of band allocation. However, the higher 5GHz ceiling and improved channel management provide an upgrade path for users moving from WiFi 6 or earlier models who still want to take advantage of WiFi 7 features such as improved modulation and multi link operation. USB 3.0 support is included for storage or tethering tasks, and the system integrates the company’s familiar software stack with options for AdGuard Home, parental controls and fast VPN throughput, including WireGuard and OpenVPN DCO at speeds up to 680Mbps.

The Flint 3e is presented as a more accessible alternative to the full tri band Flint 3, offering similar processing power and Ethernet flexibility while reducing overall wireless complexity. Its design suits users who require multi gigabit wired networking for NAS systems, workstations or mesh uplinks, while maintaining predictable WiFi coverage within standard two band environments. Power consumption remains below 25W without USB load and below 37.2W with active USB devices. This allows the router to operate efficiently in homes with multiple connected devices, including smart home hubs, streaming systems and personal storage servers.

When comparing the Flint 3e with the currently available Flint 3, the key distinction lies in wireless scope and deployment scale. The Flint 3 includes an additional 6GHz band with a 5765Mbps ceiling, a larger 8GB eMMC module and the same five port 2.5GbE layout. This gives the Flint 3 wider spectrum availability, higher aggregate throughput and more headroom for larger properties or higher density environments. The Flint 3e, by contrast, focuses on delivering similar processor performance and identical wired networking while intentionally omitting the 6GHz band to reduce cost and complexity. The result is a model suited for medium sized homes or users who rely primarily on 5GHz and wired backhaul, while the Flint 3 is positioned for broader coverage, multi floor layouts and deployments with more simultaneous wireless clients.

When will the Comet 5G, Beryl 7 and Flint 3e Be Released and What Price?

Gl.iNet’s forthcoming device trio is designed to cover distinct deployment needs across travel, remote management and wired-performance routing. The Beryl 7 travel router brings dual-band WiFi 7, USB-C power, 2.5GbE wired ports and VPN switch functionality; it is estimated to launch at a price similar to the original Beryl AX model. The Comet 5G KVM device increases flexibility by adding 5G RedCap connectivity, HDMI I/O, gigabit Ethernet and WiFi 6, positioning it in terms of design and feature set somewhere between the Comet Pro and the Slate 7; pricing is yet to be confirmed. The Flint 3e desktop router offers dual-band WiFi 7 and five 2.5GbE ports while foregoing the 6GHz band, making it more affordable than the tri-band Flint 3; this pricing strategy targets users seeking strong wired and wireless performance without full spectrum coverage. All models are expected to be formally announced at CES 2026 and become available in Q1 2026.

The Minisforum MS-02 Ultra – The First 48 Hours

The MS-02 Ultra is the latest workstation from Minisforum, and is currently undergoing testing and review here at NASCompares. However, even after just 48 hours, a whole bunch of interesting design choices and unique qwerks to the arcitecture have emerged that I wanted to cover in the meantime before the full review is complete. The MS-02 Ultra essentially trying to recapture the magic and impact of the incredibly popular MS-01 – and it is attempting this by doubling, trippling and (in some cases) quadrupling the base specifications! The Minisforum MS-02 Ultra arrives as a compact workstation that incorporates a 24-core Intel Core Ultra 9 285HX processor, up to 256 GB of ECC DDR5 memory, internal 350 W power delivery, multiple PCIe expansion options, and a network configuration that includes dual 25GbE, 10GbE, and 2.5GbE. After 48 hours of initial testing, several hardware behaviors have emerged regarding thermals, acoustics, lane distribution, storage configuration, and chassis layout. The following sections outline these early observations, supported by confirmed specifications and hands-on inspection. Stay tuned for the full review, but at least for now, let’s discuss the early highlights and low lights!

Design of the MS-02 Ultra

The internal design of the MS-02 Ultra differs considerably from earlier Minisforum workstation models and moves away from the layout used in the MS-S1 Max. Although the system retains a slide-out internal frame, the mechanism is less streamlined than the earlier S-series implementation because of how densely the components are arranged.

The interior resembles a compressed micro-tower layout, with the CPU cooling assembly, PSU, PCIe risers, and storage positions layered closely together. A dual-fan ventilation chamber spans the frontal section of the chassis, pulling air through a vented intake and directing it across the primary cooling hardware before forcing it out the rear. This arrangement appears to be a necessary response to the higher thermal output of the Ultra 9 285HX and the inclusion of multiple expansion slots, both of which require more directed airflow than Minisforum’s previous compact workstation designs.

The placement of internal components reflects the limited spatial tolerance of the 4.8-liter enclosure. The internal 350 W PSU occupies a significant section of the lower frame and includes additional power leads intended for low-profile GPU or accelerator cards, something rarely present in machines of this size. The motherboard runs across most of the horizontal section and positions the CPU vapor-chamber cooler toward the middle, while memory slots, NVMe connectors, and the PCIe riser for the combo NIC occupy the remaining pockets of available space.

Because cooling pipes and the ventilation housing sit directly above the CPU-side memory slots, Minisforum added a custom angled heatsink to ensure airflow reaches these modules. This results in a serviceable layout but one that requires more deliberate disassembly, as the compact structure prioritizes component density and thermal guidance over ease of access or open internal spacing.

Early Heat, Noise and Power Use of the MS-02 Ultra

Initial thermal behavior suggests the MS-02 Ultra is managing its compact layout with a cooling strategy built around a dual-fan chamber and a six-heatpipe radiator assisted by phase-change material. During the first setup period, surface temperatures around the chassis varied, with readings near the side ventilation panels and case edges settling around the low-to-mid 40s, while the front intake area measured lower due to the direct airflow path.

Early internal temperature checks, taken before any sustained workloads were applied, showed values consistent with a system that is heavily packed but actively cooled across multiple zones. These readings align with Minisforum’s stated 5000 RPM maximum fan speed and the intention to maintain a 100 W to 140 W CPU power envelope depending on configuration. However, because these measurements were taken during routine preparation rather than stress testing, they provide only a preliminary indication of how the system will manage long-duration loads.

Noise levels during this early period ranged from the low 30s dBA while performing software installations and background operations, with no significant fluctuations unless brief bursts of activity occurred. This behavior suggests fan control may be tied primarily to BIOS-level thermal triggers rather than granular OS-side control, something that will require further testing.

Power consumption during light activity remained in the 50 to 60 W range, which is consistent with a workstation-class system running the Ultra 9 285HX while idle or handling moderate foreground tasks. Removing the dual-25GbE combo card or disabling its slot reduced power draw by roughly 10 to 11 W, highlighting the overhead associated with multi-lane NICs and onboard controllers. These early figures provide a baseline for comparison against heavier benchmarks that will be performed in the full review.

The 25GbE, 10GbE and WiFi 7 Network Card in the MS-02 Ultra

The MS-02 Ultra’s networking implementation is centered around a PCIe-based combo card that integrates dual 25GbE SFP+ ports with two additional M.2 NVMe slots. This card is installed in the PCIe 4.0 x16 position rather than the PCIe 5.0 slot, and it includes a dedicated controller with active cooling and heatsinks that cover both the networking and storage components.

Early inspection shows the card draws a notable amount of power, which corresponds with the increased thermal and electrical requirements of Intel’s E810-class 25GbE controllers. Because of this, Minisforum’s inclusion of dedicated airflow and structural reinforcement around the card is necessary within the constrained 4.8-liter chassis. The presence of this dual-purpose add-in card also means the MS-02 Ultra’s total NVMe count depends on whether the system is configured with the 285HX version, as the lower-tier CPUs remove the combo module entirely.

Beyond the 25GbE configuration, the system includes onboard 10GbE and 2.5GbE RJ45 ports, the latter supported by Intel’s i226-LM with vPro capabilities, allowing BIOS-level remote management. The combination of high-speed SFP+, copper-based multi-gigabit ports, and embedded management options positions the system for lab, server, or virtualization roles rather than conventional desktop use.

Wireless capability is supplied via a WiFi 7 and Bluetooth 5.4 module connected through an M.2 E-Key slot, providing high-throughput wireless performance alongside its wired interfaces. Together, these connectivity features expand the system’s potential use cases, particularly for users planning to deploy virtualized environments or bandwidth-intensive tasks such as shared storage testing or multi-system clustering.

How m.2 Storage on the MS-02 Ultra is Done

The MS-02 Ultra distributes its four NVMe slots across two different locations, with two mounted on the mainboard and two integrated into the dual-25GbE combo card. The pair located on the system board are positioned on the underside, near the memory and CPU assembly, and both are listed as PCIe 4.0 x4 according to Minisforum’s documentation.

Early inspection suggests that one of these may have a PCIe 5.0 lane path available at the hardware level, though software restrictions or lane bifurcation rules may currently limit it to Gen 4 behavior. This is an area that requires further validation using a Gen 5 SSD, as the lane layout on the 285HX platform allows various allocation possibilities depending on how Minisforum assigned bandwidth between CPU, chipset, and expansion slots. These internal slots have modest vertical clearance, meaning SSDs with tall heatsinks cannot be used without removing or replacing the pre-fitted cooling structures.

The remaining two NVMe slots reside on the network combo card alongside the 25GbE controllers. These operate under different bandwidth rules depending on SSD capacity: drives up to 4 TB operate at PCIe 4.0 x4, while larger 8 TB models shift down to PCIe 3.0 x4. This behavior appears to be related to the card’s onboard controller and how its internal bifurcation splits resources between the NIC and storage lanes.

Physical space is also restricted on the card, requiring low-profile SSDs in certain positions to avoid obstruction of the cooling shroud and airflow channel. Minisforum includes an additional heatsink in the package for users installing their own drives, but using SSDs with taller factory heatsinks may be impractical. Altogether, storage layout on the MS-02 Ultra is functional and high-capacity, but with lane behaviors and physical constraints that require attention during configuration.

Memory on the MS-02 Ultra

The MS-02 Ultra provides four DDR5 SODIMM slots, but their distribution within the chassis is unconventional due to the system’s compact thermal layout. Two slots sit on the mainboard near the CPU-side M.2 positions, placed directly in the airflow path of the vapor-chamber cooler and its dual-fan assembly. Because of this, Minisforum has added a custom angled heatsink that draws air from the primary cooling channel across the modules and nearby components.

This arrangement is intended to compensate for the thermal density around the CPU area, where heat buildup would otherwise be more likely. These two slots support both ECC and non-ECC memory, though ECC functionality is active only on the 285HX model. Their placement suggests Minisforum prioritized consistent airflow over ease of access, making upgrades possible but less straightforward than on more open workstation layouts.

The remaining pair of SODIMM slots is located on the opposite side of the board, positioned away from the CPU cooling assembly and closer to the chassis frame. These modules have more breathing room but rely on passive airflow from the system’s general ventilation rather than a focused cooling path. All four slots support speeds up to 4800 MHz, with XMP profiles unavailable due to Minisforum’s implementation and Intel’s platform limitations.

During early testing, memory installation worked as expected, though the arrangement of these slots means users planning maximum 256 GB configurations will need to work within the physical constraints of the layout. Overall, the memory design reflects a tradeoff between supporting high-capacity ECC configurations and fitting the necessary cooling infrastructure into a small volume.

PCIe Card Support on the MS-02 Ultra

The MS-02 Ultra incorporates three PCIe slots arranged to maximize flexibility within its compact chassis: a PCIe 5.0 x16 slot, a PCIe 4.0 x16 slot, and a PCIe 4.0 x4 slot. The PCIe 5.0 slot is left unoccupied by default, allowing users to install a low-profile GPU or accelerator card that fits within the airflow and power constraints of the 350 W internal PSU.

Minisforum includes auxiliary power cables within the system, which is uncommon for small-form-factor workstations and indicates that the chassis is intended to support cards that require supplemental power. Because of the chassis height and width, only dual-slot, low-profile cards with modest cooling requirements are viable, but this still introduces options for compute or media workloads that benefit from hardware acceleration.

The PCIe 4.0 x16 slot is occupied in the 285HX configuration by the dual-25GbE plus dual-M.2 combo card, which introduces additional thermal and power considerations. This leaves the PCIe 4.0 x4 slot available for further expansion, provided the card used meets the system’s spatial limitations. The layout demonstrates Minisforum’s approach to balancing lane allocation between CPU, storage, and networking, especially given the 24 available PCIe lanes on the Ultra 9 platform.

Although the physical presence of three slots in such a compact volume is unusual, the arrangement is functional, and power delivery from the internal PSU supports moderate add-in card configurations. Users will need to consider airflow direction, card length, and slot occupation carefully to avoid restricting internal ventilation.

Conclusion and Verdict on the Minisforum MS-02 Ultra (So Far…)

The MS-02 Ultra presents a compact workstation design that integrates a high-core-count CPU, multiple NVMe storage options, high-speed networking, and an internal PSU within a tightly arranged chassis. Early testing indicates that the system’s thermal behavior, noise profile, and power draw are consistent with its component density, though the long-term performance of its cooling strategy requires extended benchmarking before reaching definitive conclusions. The design choices, such as the split placement of memory slots, the use of a large dual-fan cooling chamber, and the reliance on a densely packed internal layout, all reflect Minisforum’s effort to fit workstation-grade hardware into a constrained volume.

In terms of features, the dual-25GbE plus dual-M.2 combo card remains the most distinctive element, expanding the system’s potential for virtualized environments, NAS roles, and bandwidth-heavy workflows. PCIe allocation, memory configuration, and storage behavior introduce several considerations for users planning upgrades or specialized deployments. While these early observations indicate a capable and flexible platform, further testing is necessary to determine sustained thermal performance, PCIe stability under load, and real-world throughput of the networking and storage subsystems. The forthcoming full review will provide those extended results, but for now, the system presents a feature-rich design with several areas that merit deeper evaluation.

Sipeed NanoKVM Pro KVM Review

The NanoKVM Pro from Sipeed represents the latest iteration in the company’s growing range of remote management devices, developed as a more capable successor to the original NanoKVM. Building on the lessons learned from its earlier RISC-V model, this version introduces a dual-core ARM architecture and significantly enhanced system resources. The design focus shifts toward higher-resolution capture, faster data handling, and improved remote-access functionality, all within a self-contained form factor that can sit on a desk or integrate into rack systems. Supported by an open-source PiKVM-based software environment, it provides the same level of control normally associated with enterprise IPMI solutions, including BIOS access, remote mounting of ISOs, and full keyboard-video-mouse interaction through a browser interface. Unlike many entry-level devices in its category, it supports 4K capture up to 30 fps, 1080p up to 60 fps, and HDMI loop-out for simultaneous local display. Optional features such as Wi-Fi 6, PoE input, and ATX power control expand its deployment flexibility across both professional and hobbyist environments. With 1 GB of LPDDR4X memory, 32 GB of onboard eMMC storage, and the ability to run either NanoKVM OS or full PiKVM firmware, the Pro model aims to balance affordability with advanced functionality suited to modern remote administration setups. But is it any good? Let’s find out if the NanoKVM Pro deserves your money and your data.

*UPDATE 9/12/25* The original NanoKVM (so, not the device in this video/article, but the first development version) features a small on board microphone that can be activated over SSH. This *looks* like it was a case of the brand reusing an existing board and it having the mic onboard (the LicheeRV Nano – which DID mention the microphone in it’s hardware specifications, but it is not detailed on the NanoKVM spec sheets at the time of discovery). I am currently going over the NanoKVM Pro device in this video for any further issues of hardware irregularities or issues discovered since this video was published (the device has been in action for 3 weeks more now), but even early checking has shown up negative/nothing. Bottom line, that device was not released finished, and early reviews of that device absolutely SLAMMED it for security issues (again, see Aparld’s vid linked in the description!) largely related to poor practices (plain text passwords, chinese DNS, etc), so no one should be deploying it on mission-critical clients anyway. Nevertheless, this sounds like (at best) a stupid mistake by the brand, and (at worst) poorly developed and badly baked hardware. I have reached out to the brand for more on this and will add here as/when it arrives. In the meantime, check out Jeff’s Level 2 channel for his video on this, which does a solid job of nailing the salient points! You can find the original investigation of the device HERE .

NanoKVM Pro KVM Review – Quick Conclusion

The NanoKVM Pro from Sipeed is a compact, Linux-based IP-KVM device that brings enterprise-grade remote management features into an affordable, open-source package designed for homelab enthusiasts, technicians, and small-scale administrators. Built around a dual-core ARM Cortex-A53 processor with 1 GB of LPDDR4X memory and 32 GB of onboard eMMC storage, it supports 4K capture at 30 fps, 1080p at 60 fps, and HDMI loop-through for simultaneous local display, while maintaining low latency and stable frame delivery over gigabit Ethernet or Wi-Fi 6. The device integrates ATX control for power and reset functionality, allowing full BIOS-level access and system reboots without physical interaction, and can be powered via USB-C, PoE, or motherboard header connection. A 1.47-inch touchscreen with rotary encoder provides local control and monitoring, supported by an intuitive browser-based interface that enables ISO mounting, firmware updates, and encrypted remote access through built-in Tailscale VPN integration. It runs either Sipeed’s NanoKVM firmware or a full PiKVM stack, both of which are open-source and compatible with community-developed extensions, including AI-assisted features that perform local OCR and screen automation. The aluminum body ensures passive cooling and silent operation, with power draw averaging 3 to 7 watts depending on load. While early firmware builds lacked full 4K45 and H.265 support, continued updates have addressed most of these gaps, and the open nature of the platform allows for further improvement. Its minor drawbacks—such as inconsistent cable bundles, a lightweight dial, and limited CPU overhead during heavy 4K sessions—are outweighed by its flexibility, performance, and independence from proprietary cloud control. Overall, the NanoKVM Pro stands out as one of the most capable and customizable IP-KVM solutions in its price range, offering real out-of-band management power in a device smaller than a deck of cards.

NanoKVM Pro KVM Review – Design & Storage

The NanoKVM Pro adopts a compact aluminum enclosure that measures 65 by 65 by 28 millimeters, emphasizing passive cooling and durability over aesthetic design. The casing doubles as a heat spreader, transferring thermal load from the PCB through its metal base and dissipating it through the chassis surface. This construction allows it to maintain stable temperatures around 50–55°C during typical use, even with extended operation or PoE power input. The metal build makes it suitable for permanent desktop placement or rack integration, and Sipeed provides 3D printable mounting templates for both single and triple-unit configurations. Despite its small footprint, the front panel includes a 1.47-inch 320×172 capacitive touch display and a rotary encoder that enables system navigation and control without needing to connect a keyboard or mouse. The LCD serves both as a configuration interface and as a secondary monitoring screen, capable of displaying live HDMI capture, resource utilization, or user-defined Python applications.

Storage performance represents a notable improvement over the earlier NanoKVM, which relied on a microSD card for its operating system. The Pro integrates 32 GB of eMMC storage rated at approximately 300 MB/s read speeds, providing faster ISO mounting and firmware updates, as well as the ability to host lightweight scripts or utilities locally. The onboard storage can be expanded through a microSD slot positioned beside the HDMI input, supporting additional media up to 512 GB. This expansion capability allows users to keep multiple boot images or installation media accessible directly through the web interface, making it useful for managing test systems or recovery environments. In practice, transferring a 1 GB ISO via a gigabit network takes about a minute, which is considerably faster than previous microSD-based units.

Externally, the NanoKVM Pro’s layout balances density and accessibility. All primary I/O connections, including HDMI input and output, dual USB-C ports for power and HID control, and a gigabit Ethernet port, are aligned along the rear edge to simplify cable routing in both rack and desktop configurations. The USB-C design allows for flexible power sourcing, supporting either direct 5V input, PoE via Ethernet, or ATX line integration through the bundled adapter board. This modularity is complemented by a detachable ATX control board that connects through a flat ribbon cable, enabling power, reset, and LED signal passthrough from a host motherboard. When connected correctly, this board allows remote hard resets and complete power cycling through the web interface, replicating the hardware-level management seen in dedicated IPMI modules.

On the front of the device, the rotary dial and touchscreen offer combined tactile and touch control options. Short presses, rotations, and swipes allow for full system interaction, while long presses bring up system menus and app selections. The screen can also operate as a secondary display via USB connection on Windows systems, acting as a miniature monitor that mirrors or supplements the primary display output. Through custom scripts, users can configure the display to show diagnostic data, resource graphs, or network metrics, further extending the device’s use beyond remote management.

Sipeed’s packaging reflects the device’s development-oriented nature. The kit typically includes two USB-C to USB-A cables, a short HDMI cable, and an ATX interface adapter with DIP cables, although early Kickstarter units reportedly shipped with incomplete cable sets. Documentation is provided through QR-linked web guides rather than printed manuals, directing users to detailed online setup instructions and firmware repositories. This approach aligns with Sipeed’s community-driven model, where updates, firmware images, and user scripts are hosted on GitHub for open access.

Finally, the overall footprint and passive cooling design allow the NanoKVM Pro to run silently, drawing between 3 to 5 watts depending on load, or up to 7 watts when AI functions or ambient lighting are enabled. While compact enough for portable or field use, it performs best when placed on conductive or ventilated surfaces, such as a metal case or rack shelf. The Pro model’s focus on internal storage, heat management, and flexible installation makes it notably more practical than most low-cost USB KVMs and positions it closer to a self-contained remote administration terminal.

NanoKVM Pro KVM Review – Ports and Connectivity

The NanoKVM Pro provides several configuration options for both local and remote access, reflecting its design for flexible integration across various network types. Wired connectivity is managed through a full gigabit Ethernet interface, which supports both data transfer and Power over Ethernet (PoE) in certain configurations. This upgrade from the previous model’s 100 Mbps port reduces latency and ensures smoother 4K capture and ISO mounting operations across a local area network.

For environments where wired access is unavailable, Sipeed also offers Wi-Fi 6 variants that include built-in wireless support, allowing users to connect through a temporary access point and configure the device from a phone or laptop. Initial setup is handled through DHCP, displaying the assigned IP address directly on the front LCD screen. From there, users can access the web interface by entering the device’s IP address in a browser such as Chrome, with HTTPS enabled by default through a self-signed certificate.

For secure remote administration, the NanoKVM Pro includes native support for Tailscale, enabling encrypted VPN-style access across different networks without manual port forwarding. Once linked to a Tailscale account, the unit automatically joins the same virtual LAN as other connected devices, simplifying access to systems behind firewalls or NAT routers. This makes it suitable for home users who need unattended access to remote PCs or small business administrators managing distributed systems.

The device also supports USB-NCM network connections for direct link setups, as well as traditional SSH sessions for users who prefer command-line management. Because the underlying operating system is based on Ubuntu, it can also host additional networking utilities such as ZeroTier or Cloudflare Tunnels, giving users a range of choices for secure remote links depending on their existing infrastructure.

The NanoKVM Pro also supports HDMI loop-through, allowing users to connect both the target computer and a local display simultaneously. The input captures up to 4K at 30 frames per second, while the output can pass through up to 4K at 60 frames per second, depending on the connected monitor and signal mode. This dual-mode setup enables simultaneous viewing and control without interrupting the host system’s display, which is particularly useful for remote diagnostics or shared monitoring environments. In practice, the captured video stream can be viewed in near real time, with local testing showing roughly three frames of latency difference on a gigabit network connection. Combined with audio capture and bidirectional USB-HID control, the NanoKVM Pro provides a complete interface for headless or offsite system management.

NanoKVM Pro KVM Review – Internal Hardware

Internally, the NanoKVM Pro is based on the AX630C processor, a dual-core ARM Cortex-A53 SoC operating at 1.2 GHz. This represents a significant step up from the previous NanoKVM’s single-core RISC-V SG2002 processor, which struggled with multitasking and heavier video capture workloads. The new chip enables both 4K video input and real-time encoding in H.264 or H.265, as well as MJPEG for lower-latency streaming. It is paired with 1 GB of LPDDR4X memory and 32 GB of onboard eMMC storage, providing a notable improvement in performance and responsiveness when handling ISO uploads, live video feeds, or concurrent network sessions. In operation, CPU utilization typically sits around 25 to 35 percent during local access, rising to 50 to 60 percent when performing 4K capture or running AI-assisted functions.

Thermal management relies entirely on the metal enclosure acting as a passive heatsink. The system consumes roughly 3 to 4 watts at idle and up to 7 watts when AI processing or 4K capture is active. During extended use, surface temperatures can reach the mid-50 °C range, while internal readings may approach 70 °C under continuous workloads. Despite this, thermal throttling has not been observed in regular use, provided the device is placed on a conductive or ventilated surface. Users operating in warmer environments can improve dissipation by resting it on a metallic case or rack shelf, as the aluminum body is designed to transfer heat evenly across its underside. The device remains silent throughout, as no active fan is used.

Internally accessible interfaces add to its adaptability. Two USB-C ports handle power and human interface device connections, while a microSD slot offers external storage expansion or alternate firmware booting. A small 0.1 mm header provides access to two RS-232 serial ports, allowing direct console communication with servers, switches, or other serial-based equipment. This makes the NanoKVM Pro suitable not only for managing desktop systems but also for integrating with embedded or industrial hardware that lacks graphical interfaces.

Combined with the ATX breakout board for power management and the option to use the unit’s LCD as a miniature USB secondary display, these features extend its application well beyond that of a standard KVM switch.

NanoKVM Pro KVM Review – Software and Services

The NanoKVM Pro runs on a customized Linux environment built around the open-source PiKVM framework, allowing users to operate within Sipeed’s own NanoKVM interface or switch to a full PiKVM installation through the system menu. The preinstalled NanoKVM environment provides a more streamlined interface tailored to less experienced users, offering web-based management with HTTPS, user authentication, and direct BIOS-level control of connected systems. It supports remote mounting of ISO images, firmware updates, and automated scripts, all handled through an integrated file manager accessible via browser. The software operates entirely locally by default, without mandatory cloud connections, which is a notable distinction compared with many modern remote-access appliances that rely on vendor relay servers.

Once configured, users can log in through a web browser using the device’s IP address, with the default credentials set to “admin” for both username and password. The interface prompts password change on first login and provides granular control over network settings, storage, user accounts, and ATX power functions. Most settings can be modified directly through the web GUI without command-line access, although advanced users can enable SSH for deeper configuration or script automation. Firmware updates are managed via the same interface, with an option to enable preview builds for early access to experimental features such as H.265 encoding or AI integrations. The NanoKVM Pro also includes support for WebSSH, allowing browser-based terminal access to the device itself or to the connected host.

One of the most distinctive aspects of the NanoKVM Pro is its front-panel software ecosystem. The 1.47-inch touchscreen runs its own UI layer with interactive menus, swipes, and rotary input for navigation. It displays real-time system metrics such as CPU load, IP address, and network status, and can also serve as a live HDMI preview display. Beyond these default utilities, users can install small Python-based applications that render custom data on the screen. Three example apps—“coin,” “conway,” and “hello”—are included to demonstrate this feature, and advanced users can upload their own code to the /userapp directory to display statistics, weather, or system messages. Through this approach, the NanoKVM Pro acts not just as a control interface but as a miniature programmable display for local or rack-mounted setups.

Remote management services are another major focus. Tailscale is preinstalled, providing quick setup for secure, encrypted remote sessions without the need for static IP addresses or manual port forwarding. For users preferring other approaches, the device’s Ubuntu base supports additional VPN tools such as ZeroTier, WireGuard, or Cloudflare Tunnels, which can be manually installed through apt. This flexibility ensures compatibility with existing enterprise or homelab networks. The system also includes Wake-on-LAN, remote reboot, and full ATX control options, allowing users to perform power cycling or forced shutdowns directly through the web interface. The integration of these features means the NanoKVM Pro functions as an accessible alternative to server-grade remote management tools, at a fraction of their cost and complexity.

Finally, Sipeed has begun introducing experimental AI-driven functions in its firmware. These include smart assistant options that use basic optical character recognition (OCR) and contextual automation to simplify KVM operations such as copying text from the remote screen or assisting with troubleshooting prompts. Although early and limited in scope, the AI feature demonstrates the company’s effort to integrate local intelligence without relying on external cloud processing. This is complemented by the open-source nature of the platform, where both NanoKVM and PiKVM firmware images are publicly available for inspection and customization. Users can adapt the system to their own needs, extending its functionality through community scripts or integrating it into larger automation frameworks for testing, monitoring, or remote maintenance tasks.

NanoKVM Pro KVM Review – Verdict and Conclusion

The NanoKVM Pro marks a substantial improvement over its predecessor, combining more capable ARM hardware with higher capture quality, local storage, and multiple remote-access options. It bridges the gap between budget IP-KVMs and more professional management tools, delivering features like ATX control, HDMI loop-out, Tailscale connectivity, and a programmable touchscreen interface within a single, compact unit. The open-source base allows users to adapt it for highly specific workflows, whether for homelab management, small business system maintenance, or integration into test benches and automation setups. In day-to-day operation, latency and video performance remain strong over gigabit connections, with the interface proving responsive and stable. While early firmware versions lacked some advertised features such as full 4K45 capture and H.265 encoding, updates have continued to expand the system’s capabilities over time.

As a whole, the NanoKVM Pro is best understood as an evolving platform rather than a fixed appliance. Its combination of hardware versatility and accessible software design positions it as one of the more flexible low-cost KVM options available, even if certain elements, such as the dial build quality and early AI features, feel unfinished. For users seeking an independent, locally managed solution for BIOS-level control and remote diagnostics without vendor lock-in, it represents one of the strongest value offerings in its class.

Share Your Thoughts on a Perfect NAS – Best Feedback Wins One of x200 Beelink ME Mini NAS’

Why This Matters to the NAS Industry?

Beelink’s decision to crowdsource input for its upcoming NAS models reflects a wider shift in how smaller hardware manufacturers are shaping their design and development pipelines. Instead of relying solely on internal research or reseller feedback, Beelink is turning directly to the end users who actively deploy and experiment with NAS systems in home labs, media servers, and small business setups. This approach allows the company to collect detailed, practical insights on what real-world users value most, such as the balance between performance and noise, ease of access for upgrades, power efficiency, and thermal control. In context, this campaign follows Beelink’s rapid emergence as a new competitor in the DIY NAS space. The ME Mini gained traction in 2025 precisely because it delivered features that users had long requested from other compact NAS vendors—such as M.2-only storage layouts, 2.5GbE networking, and an affordable price point around the $200 mark. Now, by seeking public feedback, Beelink appears to be validating the direction of its upcoming models like the ME Pro, ME Pro X, and ME Pro Max, which are expected to feature higher networking speeds, larger capacity support, and improved cooling systems.

The company’s move also suggests it is actively testing which hardware configurations resonate most with a global user base that is increasingly focused on compact, high-throughput NAS systems rather than proprietary ecosystems. Gathering opinions on airflow, dust resistance, and modular design is likely to influence how future Beelink devices are built, potentially leading to products that better address the maintenance challenges of small enclosures and the demand for quieter yet more powerful systems. For a brand still new to network storage, this kind of direct engagement could accelerate its path toward becoming a recognised name in the wider NAS market.

Beelink Me Pro, S, X and MAX, 9x M.2, 10GbE, 5GbE NAS – NEW DIY NAS!

Note – Original Beelink ME Mini from June ’25. Written Review HERE and YouTube Video Review HERE

It has been around a year since Beelink made a major impact in the NAS sector with their $200+ 6-bay flash-based system, the Beelink ME Mini. Although the company already had a strong reputation in the Mini PC space, the ME Mini was their first dedicated NAS, and it ticked all the boxes for many users in terms of price, size, efficiency, performance, and footprint. Fast forward to Q4 2025, and I visited Beelink’s headquarters in Shenzhen, China, to learn more about their “Phase 2” NAS strategy and their expansion into a broader DIY-oriented lineup. This new wave includes several systems under the ME family, designed to remain compact and power-efficient while improving thermal management and scalability. The new range introduces the Beelink ME S, ME X, and ME Max, alongside an upgraded ME Mini Pro that refines the original platform. These systems increase NVMe capacity, introduce 3.5-inch SATA support, and feature a wider range of Intel and AMD processors.

Beelink’s roadmap spans the next 12 months, with initial launches planned for late Q4 2025 and early Q1 2026. It is clear that the company has not been idle since the success of the first ME Mini. The DIY NAS market is growing rapidly, with many users seeking OS-free prebuilt systems that balance simplicity and performance. Since Beelink Mini PCs are already popular among Proxmox and self-hosting enthusiasts, this transition into storage-focused systems could be exactly what those users have been waiting for.

Important 1: Beelink did not fund or sponsor my visit to their headquarters. They did not pay for travel or accommodation, and they have no editorial control over this article or its accompanying video.

Hardware Specifications of the Beelink ME Mini Pro, ME S, ME X and ME Max

The following information is based on a two-hour meeting with Beelink’s founder, product manager, and several engineers at the Shenzhen office, supported by translators. Notes were cross-checked against early prototype visuals and chassis designs. Some translation inaccuracies may exist, but the core technical details are accurate. It is especially notable how much performance Beelink has achieved from Intel’s N150 (Twin Lake) platform and the planned AMD FP8-series processors.

Details about the 2-bay and 4-bay systems were drawn from early 3D models and mock-up shells shared during the meeting.

Important 2: These specifications refer to devices still in development and undergoing testing, so some aspects may change before launch.

Will the New Beelink ME Mini Pro, ME S, ME X or ME Max Include Turnkey NAS Software?

This remains unconfirmed. The current ME Mini includes Ubuntu installed on a small eMMC partition, but this will be removed in the new systems. Beelink is evaluating integration of Feiniu/fnOS, a semi-open-source NAS operating system from China, though this would likely only be pre-installed on configurations that ship with drives. Users would still have the freedom to install TrueNAS, Unraid, ZimaOS, or OpenMediaVault. The software decision is not finalized yet.

Why You Should Care About the Beelink ME Mini Pro, ME S, ME X and ME Max

Beelink surprised the NAS industry in early 2025 with the ME Mini, which outperformed other compact NVMe NAS units despite being their first attempt at this market. It was roughly 60 percent cheaper than the Asustor Flashstor 6, offered more storage bays and lower temperatures than the GMKtec G9 NucBox, and provided stronger base specifications than the Terramaster D8, all while undercutting UGREEN’s offerings. While Beelink is not yet in the same league as Synology or QNAP, their rapid iteration and innovative hardware design suggest they could become a key player in compact flash-based storage solutions through 2026.

UniFi UNAS – 1 Year Later. Should You Buy Now?

It has now been one full year since Ubiquiti made its formal debut in the NAS market with the launch of the UniFi UNAS Pro, a 7-bay rackmount storage system designed to integrate seamlessly within the existing UniFi ecosystem. At launch, the device was seen as a bold but limited step into a space traditionally dominated by established brands such as Synology and QNAP, focusing more on straightforward network storage than application-heavy server functions. Over the following twelve months, the company has steadily expanded the UNAS lineup and rolled out numerous firmware and software updates, refining its NAS operating system, UniFi Drive, and addressing user feedback gathered through real-world testing. From introducing multiple new RAID configurations, encryption, fan control, and USB backup capabilities, to expanding cloud backup support and improving system responsiveness, UniFi has demonstrated a consistent approach to building out the platform incrementally rather than replacing hardware prematurely. Today, the UNAS family includes five systems spanning both desktop and rackmount designs, with capacity options ranging from 2-bay PoE-powered units to 8-bay multi-10GbE solutions. Taken together, these changes illustrate a deliberate evolution of UniFi’s NAS portfolio from a proof of concept into a structured, multi-tier ecosystem with increasing competitiveness in the storage market.

Software Features Added/Improved in UniFi UNAS in 12 Months

In the twelve months since the release of the original UNAS Pro, UniFi Drive OS has developed from a relatively simple file server interface into a more complete NAS management platform. Early releases of the Drive software offered only basic storage creation and sharing options, limited to single-pool RAID 5 or mirror configurations with few administrative tools. Over time, multiple key features have been introduced, including support for RAID 6, multiple storage pools, clustered RAID pools, and hot spare functionality, each of which was implemented through system firmware updates and confirmed through beta and public release candidates. The platform now supports encrypted volumes, user-defined snapshots, and restoration features, offering greater resilience and improved recovery options after system events or accidental deletions. These updates collectively mark a notable improvement in fault tolerance and customization, allowing the UNAS range to better serve both small business and advanced home deployments that require multiple storage tiers or redundancy strategies.

Beyond storage structure, UniFi Drive has also introduced new tools for day-to-day administration and external connectivity. Cloud backup support has expanded to include Dropbox, OneDrive, and Google Drive, replacing the early limitation to only local or UNAS-to-UNAS replication. Shared drive management now includes central administrative oversight, allowing super admins to configure and monitor user-level backup routines across all profiles. The graphical interface itself has become more responsive, adding a file activity monitor that provides timeline-based access logs for folders and files. Support for Apple Time Machine has been added, as well as improved handling of executable files via SMB, and overall network protocol efficiency has increased through back-end adjustments to Samba and NFS. With these refinements, UniFi Drive OS now feels less like an experimental branch and more like a unified part of the broader UniFi management ecosystem, with greater parity across its networking, surveillance, and storage products.

Hardware Products Added/Improved in UniFi UNAS in 12 Months

Since the launch of the original UniFi UNAS Pro in late 2024, Ubiquiti has expanded the UNAS product line into a full hardware family, each model tailored for different deployment scales and power requirements. The first expansion arrived with the compact UNAS 2, a two-bay desktop NAS powered by PoE++, marking the brand’s first use of Power-over-Ethernet as a primary power source for network storage. This device, built around a quad-core ARM Cortex-A55 CPU and 4 GB of LPDDR4 memory, aimed to serve as a lightweight edge storage unit for small offices or UniFi network environments that rely on central power distribution. Its 2.5GbE connection and USB-C port (5 Gbps) provided moderate performance for local transfers and basic backup operations, while its non-hot-swappable dual-drive cage emphasized affordability over convenience. This smaller system demonstrated UniFi’s intent to create entry-level options that could still operate within their ecosystem while maintaining core integration with UniFi Drive OS and cloud management via ui.com.

The next step up in the product family is the UNAS 4, a four-bay desktop NAS that builds directly on the UNAS 2’s design but adds more flexibility. It retains the same ARM Cortex-A55 processor and 4 GB RAM, but introduces dual M.2 NVMe slots for SSD caching or storage expansion and four 3.5-inch SATA bays for larger arrays. It still uses 2.5GbE with PoE+++ as its main power and data input, though at the time of writing, UniFi has not confirmed if the final retail version will include a secondary Ethernet port for redundancy or faster link aggregation. This model brings the UniFi storage ecosystem closer to small business-level performance, allowing for RAID 6 redundancy and improved cooling through a refined chassis design. While compact, the inclusion of NVMe caching and full integration into UniFi Drive 3.3 makes it a practical choice for users who want local storage with minimal cabling and higher data throughput.

At the higher end, the UNAS Pro 4 and UNAS Pro 8 extend the lineup into the rackmount segment, reinforcing UniFi’s move toward professional and enterprise environments. The UNAS Pro 4 adopts a 1U form factor, supporting four 3.5-inch SATA drives and two M.2 NVMe slots, while maintaining the same ARM Cortex-A57 CPU and 16 GB LPDDR4 memory as its larger sibling. It also supports dual hot-swappable PSUs for redundancy and arrives with improved thermal airflow optimized for data center racks. The flagship UNAS Pro 8 offers eight 3.5-inch bays, two rear M.2 NVMe bays, and three 10GbE ports (one RJ45 and two SFP+), making it the highest-performing UniFi NAS to date. The system consumes up to 200W under load, uses Btrfs as the primary file system, and integrates the most comprehensive cooling and failover options in the UniFi NAS lineup. Together, these models illustrate UniFi’s full-tier hardware strategy: from PoE-powered desktop storage to rackmount systems supporting multi-gigabit networking and dual redundant power.

Fixes, Changes and Improvements in UniFi UNAS in 12 Months

Over the past year, UniFi has steadily refined the UNAS operating environment, addressing a number of software and usability issues identified by early adopters of the original UNAS Pro. Many of these improvements were released through incremental firmware updates across both the Drive OS and UniFi Controller platforms. Among the most significant early fixes was the resolution of file handling inconsistencies between the built-in web file manager and SMB-based network access, which previously caused discrepancies when deleting or restoring data.

This issue, which affected synchronization between the NAS GUI and mapped network shares, has now been corrected. Similarly, early memory leak and permission errors during large-scale SMB transfers have been resolved through back-end optimization, reducing skipped files and improving overall data reliability. Updates to the system logs and storage integrity checks also brought clearer reporting of failed transfers and RAID rebuild activity, ensuring that users now receive consistent system notifications and warnings.

Another key focus for UniFi’s development team over the last twelve months has been user management, network integration, and environmental control. Earlier versions of Drive OS restricted backup operations to individual users, preventing the super admin from managing backups or schedules across the system. This has since been rectified, allowing full central backup management, while user permission hierarchies have been expanded to distinguish between local-only accounts, remote accounts, and enterprise identity-linked users.

Environmental improvements include the long-requested fan control interface, which gives users the option to manually adjust fan speeds or keep automatic control active depending on temperature thresholds. The addition of real-time thermal monitoring, more accurate CPU and drive temperature reporting, and improved resource graphs now make it easier to track system health. The Drive 3.3 release also introduced a refined GUI with more responsive dashboard elements, consistent data updates in the system console, and a correction to the long-standing uptime reporting bug that falsely displayed “20,000 days active.”

Missing Features and Planned Features in UniFi UNAS in the Next 12 Months

Despite significant progress since the launch of the original UNAS Pro, several key features are still missing from the UniFi Drive OS ecosystem. The most frequently requested addition from users continues to be iSCSI target and initiator support, a capability that would allow direct block-level storage mapping for virtual machines and professional applications. Its absence limits the UNAS series to traditional network file protocols such as SMB and NFS, which are less efficient for tasks requiring raw storage access or integration with virtualization platforms. Equally, the continued lack of RAID 0 support restricts high-performance users who are willing to trade redundancy for speed. While RAID 6 and clustered pools have been introduced, there is still no configuration option that prioritizes sequential throughput over redundancy. Another omission is a native UniFi Drive client tool for Windows, macOS, or Linux that would allow direct desktop synchronization, local file pinning, and on-demand streaming similar to Synology Drive or Dropbox. At present, users must rely on the web interface or manually mapped drives, which limits productivity and offline access.

Looking forward, UniFi has hinted through developer notes and recent firmware structure that the ENAS (Enterprise NAS) line will introduce ZFS file system support, marking a major shift toward high-end storage with data integrity and snapshot efficiency beyond Btrfs. This aligns with the observed trend of UniFi testing ZFS integration within their enterprise roadmap, possibly extending limited functionality to future revisions of the Pro 4 and Pro 8. The upcoming UniFi Drive 3.3 and 3.4 updates are also expected to expand fan and power scheduling, allowing users to define specific system on/off cycles and control Ethernet port activation schedules, effectively creating customizable air-gap routines. Additionally, UniFi’s roadmap includes exploring expansion connectivity, potentially leveraging unused 10GbE interfaces for network-based expansion enclosures or storage clustering between UNAS units. This would mirror the high-availability (HA) or expansion behavior of established NAS brands, though implemented entirely over the UniFi network layer.

UniFi is also expected to refine NVMe handling, particularly the ability to use installed M.2 drives as standalone storage pools rather than just as cache devices. The introduction of pool-level tiering and dynamic storage balancing could allow users to automatically assign workloads between SSD and HDD pools, improving I/O efficiency without manual adjustment. Beyond hardware-level improvements, there is ongoing demand for the integration of UniFi Protect within the NAS family, allowing video surveillance to run on the same physical storage units rather than on separate NVRs. Although UniFi has historically separated its Protect and Drive ecosystems, internal hardware similarities between the UNAS Pro and UNVR Pro systems suggest eventual compatibility is possible. Finally, more advanced backup filters, bandwidth scheduling, and automated snapshot policies are likely to appear in the next major OS iteration as part of UniFi’s effort to close the gap with traditional NAS brands while maintaining its minimalist network-first design approach.

Conclusion and Verdict – Is the UniFi UNAS Good Now?

One year after the launch of the original UniFi UNAS Pro, the UniFi NAS platform has evolved from a single experimental product into a diversified ecosystem that spans both desktop and rackmount storage. The introduction of the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8 demonstrates that Ubiquiti is committed to building a scalable product range capable of serving both home users and small business environments. On the software side, the development of UniFi Drive OS has been steady and deliberate, with a focus on improving reliability, expanding RAID options, and tightening cloud and local backup integration. These changes, combined with improved temperature management, admin-level control, and performance tuning for SMB and NFS, have resulted in a more mature and dependable NAS experience than the early versions from 2024. However, the range remains deliberately streamlined, prioritizing simplicity and ecosystem integration over third-party app support or virtualization features.

Looking ahead, the next phase of the UniFi NAS roadmap appears to focus on deeper enterprise integration and feature parity with long-standing NAS brands. The likely addition of iSCSI, ZFS, and network-based expansion options will determine how far UniFi can move beyond entry and mid-range use cases. The hardware continues to rely on ARM processors rather than x86, which reinforces UniFi’s focus on efficiency and security but limits advanced workloads such as containerization and VM hosting. Even so, the value proposition remains strong, particularly given the aggressive pricing across the entire UNAS range and its seamless compatibility with the existing UniFi infrastructure. Overall, UniFi’s NAS systems are no longer a novelty—they represent a serious and rapidly developing branch of the company’s portfolio that has gained stability, utility, and confidence within just one year.

Review of the Sharge Disk Pro Mobile Hub and Docking Station

The Sharge Disk Pro is a compact external SSD and multifunction USB hub aimed at users who need additional high-speed storage and connectivity for their mobile or desktop devices. Measuring roughly the size of a credit card and just 11mm thick, it merges solid-state storage, data transfer, and video output within a single enclosure. The device is equipped with an integrated USB-C cable, a fan-assisted thermal system, and a magnetic mounting design that allows it to attach securely to compatible smartphones, handheld gaming consoles, or laptops. Available in 1TB, 2TB, and 4TB versions, it uses 162-layer 3D TLC NAND flash and supports sustained 10Gbps transfers via USB 3.2 Gen 2. The Disk Pro also includes active and automatic fan modes designed to regulate temperature during extended operation. Unlike a standard enclosure, it has no option for user-upgradeable storage, with Sharge citing the closed design as essential for cooling performance. The product is currently being crowdfunded through Kickstarter, with early pricing beginning at $189 for the 1TB model and scaling to $469 for the 4TB version, and retail availability expected after the campaign concludes.

Sharge Disk Pro Review – Quick Conclusion

Sharge Disk Pro Review – Design and Storage

The Sharge Disk Pro adopts a slim, rectangular chassis with a transparent, cyberpunk-style exterior typical of the brand’s product line. At just 11mm thick and weighing approximately 150g, it remains small enough to slip into a pocket or attach directly to the rear of a device via its magnetic backplate. Sharge provides several self-adhesive magnetic rings that enable mounting on laptops, smartphones, and handheld consoles, including MagSafe or Qi2-compatible models. This mounting flexibility is particularly useful when connecting the device to mobile systems with limited space or single-port connectivity, allowing it to remain flush with the device body during use rather than dangling on a cable.

Internally, the Disk Pro integrates TLC NAND flash storage that is permanently sealed within the casing. It comes in 1TB, 2TB, and 4TB configurations, but does not support user replacement or expansion. Sharge has stated that opening the casing would compromise the structural integrity of the fan-assisted cooling system, which directs airflow directly across the SSD and controller. While this closed design limits user flexibility, it contributes to improved durability and controlled thermals during sustained data operations, addressing a common weakness in other compact SSDs that tend to throttle under heavy load.

Externally, the unit uses an aluminium frame combined with a transparent plastic shell that reveals parts of its internal structure. The materials provide both aesthetic appeal and heat dissipation, with the aluminium core helping to channel heat away from the NAND and controller components. The integrated USB-C cable is short and reinforced, designed for use with laptops, tablets, and mobile phones without introducing unnecessary slack. Although the compactness is one of the Disk Pro’s strongest traits, it does come at the cost of expandability and limited repair potential due to the permanently sealed housing.

From a storage standpoint, Sharge’s choice of 162-layer 3D TLC NAND provides a balance of endurance and sustained performance, suitable for large data transfers, video capture, or use as external storage for gaming devices. Each model is preformatted for exFAT to ensure cross-platform compatibility between Windows, macOS, Android, and Linux systems. The inclusion of integrated power management also means the SSD can draw adequate power even when connected to low-output ports, with the fan and SSD operating efficiently under mobile conditions.

The Disk Pro’s overall form factor and integrated features place it closer to a high-performance portable hub than a simple external SSD. Its sealed construction, integrated active cooling, and additional connectivity are intended to reduce heat buildup, protect data integrity, and simplify on-the-go workflows. For professionals working with large 4K or 8K media files, or gamers seeking extended storage without extra cables, this design approach represents a different balance of portability and utility compared with most standard SSD enclosures on the market.

Sharge Disk Pro Review – Ports and Connections

The Sharge Disk Pro is built around a compact yet functional hub layout that integrates five active ports alongside the internal SSD. These include one HDMI 2.1 output, one USB-C port, one USB-A 3.2 Gen 2 port, and one USB-A 2.0 port, all managed by independent controller chips to prevent bottlenecks when multiple peripherals are in use. The inclusion of an HDMI 2.1 output enables video output up to 8K at 30Hz or 4K at 144Hz, depending on the connected device’s bandwidth. This makes it suitable for use with laptops, tablets, and compatible gaming consoles where both data access and display output are needed simultaneously. The USB-C port provides up to 100W input for power delivery passthrough, while the SSD and downstream ports can output up to 80W, allowing users to charge connected devices while maintaining full data and display functionality.

The built-in USB-C cable is one of the device’s defining physical features. Permanently attached to the chassis, it eliminates the need for separate cabling, reducing potential signal degradation and clutter. The short length ensures a secure connection with minimal strain, making it well-suited for handhelds and mobile phones where portability is essential. However, because it is non-removable, users have no option to replace the cable if it wears out or becomes damaged. The Disk Pro operates entirely over USB 3.2 Gen 2 (10Gbps), meaning it cannot exceed around 1GB/s transfer speeds, but remains fast enough for sustained high-volume workloads and video file handling.

Sharge also includes a 100W USB Power Delivery pass-through system designed for multi-device setups. When connected to a charger, the Disk Pro can simultaneously power a laptop or smartphone and operate as an SSD hub. The system manages current allocation automatically between the SSD, active ports, and the connected host device, maintaining stability under load. Users can switch the SSD off using a built-in hardware toggle to conserve NAND lifespan or operate solely as a docking station. This is a useful inclusion for those who primarily use the Disk Pro as a connectivity bridge rather than as continuous storage.

Despite its small dimensions, the hub’s port spacing and layout are designed for accessibility. Each connection point is positioned to avoid cable overlap, which can be problematic in other compact hubs. The HDMI port sits at the rear next to the USB-C power input, while the USB-A ports are side-mounted to support accessories such as flash drives, keyboards, or game controllers. This arrangement allows the device to function as both a desktop companion and an attachable expansion unit for mobile platforms.

• Interface Standard: USB 3.2 Gen 2 (10Gbps)

• Integrated Cable: Built-in USB-C, fixed length

• USB Ports: 1 x USB-C PD (100W input / 80W output), 1 x USB-A 3.2 Gen 2, 1 x USB-A 2.0

• Video Output: HDMI 2.1 supporting 4K 144Hz / 8K 30Hz

• Power Delivery: 100W input passthrough, 80W total output

• Controller Architecture: Three independent controller chips for port load management

• SSD Disable Switch: Hardware button to disable SSD for hub-only use

Sharge Disk Pro Review – Performance Tests

In practical testing, the Sharge Disk Pro delivered performance that closely aligned with its stated specifications. Using AJA System Test on a Windows 11 PC, sustained read speeds averaged between 800 and 900 MB/s, while write speeds remained consistent at around 700 to 800 MB/s across multiple test cycles. These results are in line with expectations for a USB 3.2 Gen 2 (10Gbps) interface, which typically caps out at 1,000 MB/s due to bus limitations. During repeated five-minute transfer tests using 256MB file blocks, there was no noticeable performance degradation or thermal throttling, confirming that the integrated fan and heatsink design effectively maintained stable throughput even under extended workloads. Sequential transfers performed best, while random 4K operations showed typical limitations of USB-based external drives, making it more suited for large media file transfers rather than small transactional data.

Thermal performance was a key focus of Sharge’s design, and testing showed the fan to be highly effective at maintaining low SSD temperatures. With the fan disabled, idle temperatures hovered around 35–37°C, rising only slightly during short file operations.

When the fan was activated in Auto mode, the device maintained temperatures around 34–35°C externally, and the SSD’s internal sensors never exceeded 40°C during prolonged testing. In Turbo mode, which spins the fan up to 10,000 RPM, the system achieved an additional reduction of around 5°C compared to passive cooling. For comparison, typical compact SSDs of similar capacity can reach over 60°C under similar workloads, confirming that active cooling provides tangible longevity and stability benefits for the NAND and controller components.

Noise measurements taken during operation showed moderate but noticeable levels. With the fan off, the Disk Pro was entirely silent, as expected for a solid-state design. When active cooling was engaged, noise levels ranged between 42 and 43 dBA at a one-meter distance, roughly equivalent to a quiet office environment. Although audible, it was far from intrusive and balanced against the benefit of consistent thermal performance. The fan’s automatic speed curve effectively adjusted to thermal demands, rarely ramping to maximum unless under sustained high-intensity transfers. Users who prioritize silence can manually disable the fan when operating in cooler environments or when using the device primarily for intermittent transfers.

The internal SSD uses 162-layer 3D TLC NAND with a proprietary controller tuned for consistent throughput rather than peak burst speeds. The design choice ensures reliable operation across mixed workloads such as 4K video capture, game installation, and system backups. The integrated power delivery circuitry also maintained stability under simultaneous port loads, allowing the SSD and connected peripherals to perform consistently without power drops. While the lack of hardware encryption may be a drawback for enterprise or security-focused users, the drive remains fully compatible with software encryption solutions available on Windows, macOS, and Android.

• Interface Speed: USB 3.2 Gen 2 (10Gbps, ~1,000 MB/s theoretical)

• Measured Read Speed: 800–900 MB/s sustained

• Measured Write Speed: 700–800 MB/s sustained

• NAND Type: 162-layer 3D TLC NAND (BiCS6)

• Cooling System: Active fan with Auto (7,000 RPM) and Turbo (10,000 RPM) modes

• Operating Temperatures: 34–40°C under sustained load

• Noise Levels: 42–43 dBA under fan operation, 0 dBA passive

• Power Draw: 60W power input for device and fan operation, 100W passthrough charging support

Sharge Disk Pro Review – Verdict and Conclusion

The Sharge Disk Pro represents a deliberate departure from conventional external SSDs, offering a hybrid approach that merges high-speed storage with full USB hub functionality in a portable form factor. Its sealed, magnetically mountable chassis and integrated fan system address the common issue of heat buildup in compact SSDs, maintaining reliable performance over long transfers. While its 10Gbps interface limits absolute throughput to around 1GB/s, the consistent sustained speeds and controlled thermals make it suitable for demanding use cases such as 4K editing, live data capture, or console game storage. The fixed internal SSD and integrated cable limit upgradeability and repair potential, but they also contribute to its streamlined design and compact efficiency.

For users seeking a versatile storage expansion that also replaces a traditional docking station, the Disk Pro’s multi-port setup and cooling design provide clear practical benefits. However, those wanting modular storage or hardware encryption will find its closed system less appealing. Ultimately, it’s a well-engineered portable hub that balances mobility, temperature management, and performance more effectively than most devices in its class. If the retail version maintains the same build and stability demonstrated in testing, it will fill a distinct niche for creators and professionals needing fast, thermally stable external storage in a highly compact form.

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

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

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

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

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

The power supply is a single 90W external brick, keeping internal temperatures lower and simplifying maintenance.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Terramaster TOS 6 Software

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

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

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

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

Verdict? The New4-Bay NAS Score to Beat?

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

The UniFi UPS-Tower 600W UPS Review

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

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

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

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

The UniFi UPS-Tower UPS Review – Design & Connectivity

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

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

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

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

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

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

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

The UniFi UPS-Tower UPS Review – Internal Hardware

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

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

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

The UniFi UPS-Tower UPS Review – Functionality

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

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

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

The UniFi UPS-Tower UPS Review – Conclusion and Verdict

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

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

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

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

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

The UNAS Pro 8 NAS

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

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

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

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

The UNAS 2 NAS

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

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

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

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

The UNAS Pro 4 NAS

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

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

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

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

The UNAS 4 NAS

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

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

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

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

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

UniFi Drive 3.3 Update?

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

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

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

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

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

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

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

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

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

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

UniFi UNAS Pro 8 Review – Quick Conclusion

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

UniFi UNAS Pro 8 Review – Design & Storage

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

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

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

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

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

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

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

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

UniFi UNAS Pro 8 Review – Internal Hardware

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

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

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

UniFi UNAS Pro 8 Review – Connectivity & Throughput

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

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

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

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

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

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

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

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

• Management: Ethernet and Bluetooth 4.1 setup/admin

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

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

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

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

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

UniFi UNAS Pro 8 Review – Software and Services

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

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

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

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

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

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

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

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

UniFi UNAS Pro 8 Review – Verdict and Conclusion

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

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

The UniFi UNAS 2 NAS Review – Value vs Scale

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

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

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

UniFi UNAS 2 Review – Quick Conclusion

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

UniFi UNAS 2 Review – Design

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

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

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

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

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

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

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

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

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

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

UniFi UNAS 2 Review – Internal Hardware

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

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

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

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

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

UniFi UNAS 2 Review – Connectivity & Performance

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

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

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

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

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

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

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

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

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

• Power Supply: 60W PoE++ injector included

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

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

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

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

UniFi UNAS 2 Review – Software and Services

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

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

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

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

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

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

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

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

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

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

UniFi UNAS 2 Review – Verdict and Conclusion

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

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

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

Quick Summary of the Synology DS1825+ NAS

Synology DS1825+ NAS Review HERE

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

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

Quick Summary of the UGREEN DXP8800 PLUS NAS

UGREEN DXP8800 PLUS NAS Review HERE

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

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

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

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

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

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

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

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Internal Hardware

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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