The Best RAID 5 Ready 4/5/6-Bay NAS Servers of 2025

Multi bay NAS units in the 4,5 and 6 bay bracket have become the default choice for users who want a single chassis that can handle RAID 5 or larger arrays, mix HDD and NVMe storage and still fit under a desk or on a shelf. This roundup looks at systems released in 2025 that sit in that space, from compact ARM based 4 bay boxes up to more expandable x86 platforms with additional M.2 slots and higher network bandwidth. The focus is on how each unit balances raw storage capacity across SATA and NVMe, the type of RAID and pool layouts it can realistically support, and the power, noise and feature overhead that comes with those choices, so readers can match a chassis to their plans for backup, media, virtualisation or general home lab use without stepping up to larger, more complex rack or 8 bay solutions.

#1 Minisforum N5 NAS – $599 to $749 HERE

SPECS: AMD Ryzen 7 255 8 core 16 thread up to 4.9 GHz – up to 96 GB DDR5 via 2 SODIMM slots – 5 x 3.5″/2.5″ SATA bays – 1 x 10 GbE RJ45 / 1 x 5 GbE RJ45 – 3 x M.2 NVMe or U.2 SSD slots (PCIe 4.0, mixed x1 and x2 lanes) plus 128 GB OS storage.

With 5 SATA bays rated for up to 22 TB per disk and 3 PCIe 4.0 NVMe or U.2 positions, the N5 can be configured as a hybrid array where high capacity RAID 5 or RAID 6 sits on HDDs while SSDs are used for fast pools or tiered storage. MinisCloud OS exposes ZFS style RAID options including RAID 0, 1, 5 and 6, snapshots and compression, so the storage layout can be tuned for sequential workloads, mixed containers or heavier virtualisation without replacing the base system. The Ryzen 7 255 and Radeon 780M iGPU give it enough compute and PCIe bandwidth for multi gig throughput over the combined 10 GbE and 5 GbE interfaces, but they also raise power use and thermal output compared with simpler ARM or low end x86 models. In a 4 or 5 bay context it therefore suits users who expect to keep expanding with higher density drives and multiple NVMe pools over several years, rather than those who just need a small RAID 5 and basic apps.

What we said in our July ’25 Review HERE:

The Minisforum N5 Pro is an impressive and highly versatile NAS platform that successfully combines the core strengths of a storage appliance with the capabilities of a compact, workstation-class server, making it suitable for demanding and varied use cases. Its defining features include a 12-core Ryzen AI 9 HX PRO 370 CPU with 24 threads and onboard AI acceleration up to 50 TOPS, support for up to 96GB of ECC-capable DDR5 memory for data integrity, and a hybrid storage architecture offering up to 144TB total capacity through a mix of five SATA bays and three NVMe/U.2 slots. Additional highlights such as ZFS file system support with snapshots, inline compression, and self-healing, along with high-speed networking via dual 10GbE and 5GbE ports, and expansion through PCIe Gen 4 ×16 and OCuLink interfaces, position it well beyond the capabilities of typical consumer NAS systems. The compact, fully metal chassis is easy to service and efficiently cooled, enabling continuous operation even under sustained virtual machine, AI, or media workloads.

At the same time, the bundled MinisCloud OS, while feature-rich with AI photo indexing, Docker support, and mobile integration, remains a work in progress, lacking some enterprise-grade polish, robust localization, and more advanced tools expected in mature NAS ecosystems. Minor drawbacks such as the external PSU, the thermally challenged pre-installed OS SSD, and the higher cost of the Pro variant relative to the standard N5 are important to weigh, particularly for users who may not fully utilize the Pro’s ECC and AI-specific advantages. For advanced users, homelab builders, and technical teams who require high compute density, flexible storage, and full control over their software stack, the N5 Pro delivers workstation-level performance and configurability in NAS form—offering one of the most forward-thinking and adaptable solutions available today in this segment.

Premium $1000+ pricing may be hard to justify for users who don’t need ECC memory or AI capabilities compared to the standard N5 at $500+

#2 UGREEN NASync DH4300 Plus – $369 to $409

SPECS: Rockchip RK3588 8 core ARM up to 2.0 GHz – 8 GB LPDDR4X – 4 x 3.5″/2.5″ SATA bays – 1 x 2.5 GbE RJ45 – no internal M.2 SSD slots.

The DH4300 Plus concentrates all of its storage on 4 SATA bays with support for RAID 0, 1, 5, 6 and 10, up to a stated 120 TB raw using 30 TB disks, which makes it a straightforward choice for traditional RAID 5 capacity rather than mixed media architectures. The absence of M.2 slots means there is no internal SSD cache tier, although SSDs can still be used in the main bays if lower latency is required, at the cost of capacity per bay. In return, the RK3588 SoC and LPDDR4X memory keep power consumption relatively low, with quoted figures under 25 W under load, and the 2.5 GbE interface is enough to saturate what 4 mechanical drives in RAID 5 or RAID 6 can usually deliver. UGreen’s UGOS Pro platform adds a container system, snapshot capable file services and consumer facing features such as AI photo indexing, so for a 4 bay RAID 5 appliance the trade off is clear: a fixed, HDD focused storage layout with no internal NVMe, in exchange for low complexity, modest power draw and a simple upgrade path based mainly on higher capacity disks.

What we said in our July 2025 Review:

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

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

#3 Beelink ME Mini N150 – $259 to $299

SPECS: Intel N150 quad core up to 3.6 GHz – 12 GB LPDDR5 (16 GB variants available) – 6 x M.2 SSD slots (1 preinstalled 2 TB PCIe 3.0 x2, 5 user accessible PCIe 3.0 x1) plus 64 GB eMMC – dual 2.5 GbE RJ45.

The ME Mini replaces conventional 3.5″ or 2.5″ bays with 6 M.2 sockets, one wired as a PCIe 3.0 x2 system drive and 5 as PCIe 3.0 x1, giving up to 24 TB of all flash capacity in a 99 mm cube chassis when populated with current 4 TB modules. Because there is no SATA backplane, any RAID is provided by the chosen OS or software layer, whether that is a Linux distribution, ZFS based platform or a dedicated NAS operating system installed in place of the default Windows image. From a power and thermal standpoint, the combination of an 8 to 10 W class Intel N150 and low voltage NVMe SSDs keeps system draw relatively low compared with multi bay HDD units, while still allowing the dual 2.5 GbE ports to be used effectively for small sequential workloads and many concurrent small reads. In practical terms this makes the ME Mini a compact all flash alternative to 4 or 5 bay HDD chassis for users willing to handle their own OS choice, trading spinning disk capacity and native RAID controls for high IOPS, small physical footprint and lower acoustic impact.

What we said in our June ’25 Review HERE:

The Beelink ME Mini NAS delivers an uncommon blend of size, functionality, and efficiency in a market segment often dominated by larger, louder, and less integrated alternatives. It is not designed to compete with traditional enterprise-grade NAS devices or modular, scalable solutions for prosumers. Instead, its strengths lie in targeting the needs of home users who want a quiet, energy-efficient storage solution that is easy to deploy, aesthetically unobtrusive, and capable of handling daily tasks such as media streaming, file backup, or soft routing. The inclusion of six M.2 NVMe SSD slots—paired with a Gen 3 x2 system slot—offers a rare level of expansion in such a small enclosure. The integration of an internal PSU, silent fan-assisted cooling, and a surprisingly effective thermal design are thoughtful touches that differentiate it from the majority of DIY NAS mini PCs.

That said, it is not without limitations. The memory is non-upgradable, thermal accumulation at the base suggests room for improvement, and bandwidth ceilings imposed by Gen 3 x1 lanes will constrain users who demand high parallel throughput. Still, for its price point—particularly when pre-order discounts are applied—the ME Mini offers significant value, especially when compared to ARM-based NAS solutions with similar or lower specifications. With bundled Crucial SSD options and support for a wide range of NAS operating systems, it positions itself as a ready-to-go platform for tech-savvy users wanting to avoid the assembly of a fully DIY system. Overall, while not a product for every use case, the Beelink ME Mini succeeds in its aim to be a compact, stylish, and capable home NAS.

#4 TerraMaster F4-425 Plus – $549 to $599

SPECS: Intel N150 quad core up to 3.6 GHz – 16 GB DDR5 (1 slot, up to 32 GB) – 4 x 3.5″/2.5″ SATA bays – 2 x 5 GbE RJ45 – 3 x M.2 2280 NVMe PCIe 3.0 x1 slots.

The F4-425 Plus is built as a hybrid 4 bay chassis with 3 additional M.2 NVMe slots, allowing a mixed layout where HDDs hold bulk data in conventional RAID while SSDs are used for cache or as separate RAID 5 or RAID 1 pools. TerraMaster quotes support for up to 120 TB on the 4 SATA bays plus up to 24 TB across the 3 M.2 sockets, and TOS 6 can treat the SSDs as either acceleration for HDD arrays or discrete volumes for latency sensitive workloads. The dual 5 GbE ports give a potential aggregated 10 Gb link that better aligns with SSD capable throughput than 1 GbE or single 2.5 GbE designs, while the N150 CPU and 16 GB DDR5 memory are sized for small office backup, virtualisation light use and multi user file serving rather than heavy compute tasks. From a RAID planning perspective the device suits scenarios where a 4 disk RAID 5 or RAID 6 on large SATA drives is combined with SSD based scratch or application volumes, without moving to a physically larger 6 or 8 bay enclosure.

What we said in our October 2025 Review:

The TerraMaster F4-425 Plus demonstrates how far the company’s mid-range NAS lineup has progressed in terms of hardware refinement and real-world usability. By combining Intel’s efficient N150 processor with 16GB of DDR5 memory, dual 5GbE connectivity, and triple M.2 NVMe slots, it provides a specification normally reserved for higher-priced units. The build quality, centered around a full-metal chassis and quiet cooling design, contributes to consistent thermals and low power usage even under multi-day workloads. While the design omits premium touches like drive locks or redundant fans, the emphasis on practicality and efficient cooling makes it a dependable solution for continuous operation. From a user experience perspective, the integration of TOS 6 represents TerraMaster’s most stable and capable operating system to date, offering improved security features, cloud synchronization tools, snapshot management, and flexible storage configurations that appeal to both home and small office users.

From a value standpoint, the F4-425 Plus stands out as one of the most competitively priced NAS units in its category. At $569.99, or $484.99 during the initial discount period, it delivers strong network and storage performance that aligns closely with rivals from Synology and QNAP while retaining open installation flexibility for third-party platforms such as Unraid or TrueNAS. Its combination of high-speed connectivity, compact design, and mature software environment makes it an appealing option for anyone seeking a 4-bay system capable of multitasking across media streaming, data backup, and light virtualization. Although it cannot fully match the polish of Synology DSM or the plugin ecosystem of QNAP QTS, TerraMaster has successfully positioned this device as a bridge between affordability and professional performance, solidifying its place as one of the more balanced NAS releases of 2025.

#5 Synology DiskStation DS1525+ – $799 to $899

SPECS: AMD Ryzen V1500B quad core 2.2 GHz – 8 GB DDR4 ECC (2 slots, up to 32 GB) – 5 x 3.5″/2.5″ SATA bays – 2 x 2.5 GbE RJ45 – 2 x M.2 2280 NVMe slots plus 1 x PCIe 3.0 x2 expansion slot.

The DS1525+ follows Synology’s typical pattern of putting all primary capacity on 5 hot swap SATA bays while reserving 2 internal M.2 slots for NVMe SSDs used as cache or, in some scenarios, as separate pools under DSM. Raw capacity on the main bays is specified around 100 TB, and with 2 supported DX525 expansion units the platform can scale to 15 drives and roughly 300 TB, giving it more growth headroom than most standalone 4 or 5 bay devices. DSM prefers Synology certified NVMe modules for cache, and the typical deployment is therefore a RAID 5 or RAID 6 array on the 5 SATA disks with SSD cache accelerating small random access workloads such as virtual machines, databases or heavy Synology Drive usage. The Ryzen V1500B and ECC memory are adequate for that role and integrate with DSM features like Btrfs snapshots, Active Backup Suite and Virtual Machine Manager, but they do not drive NVMe storage as a primary all flash tier in the way more other NAS brands do (i.e you can only use them for caching, or limited ‘synology only SSD’ use for pools to comparatively lower performance than most). The result is a system where the storage design is conservative but predictable, emphasising SATA RAID resilience and cache-assisted responsiveness rather than radical hybrid layouts, backed by a mature software stack.

What we said in our July 2025 Review:

The Synology DS1525+ is a capable and well built NAS that continues the company’s focus on dependable performance, solid build quality and very tight integration with DSM, which is the main justification for choosing this platform over more open hardware from other vendors. Its compact 5 bay design, quiet operation and scalable storage make it suitable for small offices, creative studios and prosumers who want a single system to handle file serving, backup and light virtualisation. The inclusion of a server grade Ryzen V1500B CPU and ECC memory support provides predictable performance for DSM services such as Synology Drive, Synology Office, Virtual Machine Manager and Surveillance Station, while the dual M.2 slots and PCIe expansion give enough headroom for cache and 10 GbE upgrades. DSM itself remains the central strength: Btrfs based volumes with snapshots, Active Backup Suite for Windows, Linux and SaaS workloads, integrated directory and access control, and relatively polished mobile and web clients mean that much of the day to day administration, recovery and user management can be handled inside a single, consistent interface rather than across multiple third party tools.

More importantly for many buyers, Synology’s 2025 Plus series, including the DS1525+, now fully supports third party hard drives without on screen warnings or functional restrictions, which removes a major concern from earlier policies and restores flexibility for users reusing existing disks or mixing capacities and brands under DSM’s storage manager. By contrast, M.2 SSD support remains locked to Synology’s own validated modules, so NVMe upgrades for DSM cache or SSD pools still carry a vendor premium and limit hardware choice. The switch from four 1 GbE ports to two 2.5 GbE ports trades some port level redundancy for higher per port bandwidth and may require compatible switches to realise the benefit, but DSM can aggregate links, shape traffic and expose detailed monitoring from within its own interface.

In practice the DS1525+ suits users who prioritise DSM’s software maturity, integrated backup and collaboration stack and the relative simplicity of a managed ecosystem over maximum hardware openness; for those who want unrestricted NVMe choices or the highest raw performance per dollar, more generic x86 systems with looser SSD validation may be a better fit.

Taken together, the Minisforum N5, UGREEN DH4300 Plus, Beelink ME Mini, TerraMaster F4-425 Plus and Synology DS1525+ outline the main paths available in the 4,5 and 6 bay segment in 2025: high core count x86 with mixed SATA and NVMe for heavier workloads, low power ARM with straightforward 4 bay RAID for cost sensitive deployments, compact all flash designs where capacity scales through M.2 rather than 3.5 inch bays, hybrid chassis that combine 4 bay RAID with several SSD slots, and software led platforms where DSM’s feature set is the primary reason to buy. None of them is universally better than the others; the practical choice depends on whether the priority is raw HDD capacity in RAID 5 or RAID 6, a larger number of NVMe slots, lower power use, or tighter integration of backup, collaboration and virtualisation tools. For buyers who understand how they intend to balance SATA and NVMe storage over the next few years, these units set a useful reference point for what can realistically be expected from a modern 4,5 or 6 bay NAS without moving to larger rackmount or 8 bay hardware.

Best NAS of the Year 2025

Network attached storage in 2025 has shifted from being a niche utility to a central part of how many homes, studios and small businesses manage data. Rising storage needs, more capable low power CPUs and a renewed interest in self hosted services have produced a wave of compact, power efficient systems alongside more traditional multi bay enclosures. This article identifies a small group of NAS devices that stood out during 2025 for their hardware design, price-to-performance balance or the specific problems they address, rather than for brand familiarity alone. To qualify for inclusion, a NAS had to be commercially available for general sale during 2025, not an older carry over model or a crowdfunded prototype. No Kickstarter, Indiegogo or pre production units were considered, and devices that only existed as region locked or short lived batches were excluded where availability could not be reasonably confirmed. Both turnkey systems with bundled NAS operating systems and OS agnostic, barebones style hardware are included, provided they offer a clear proposition for real world use in home lab, small business or mobile workflows.

Honourary Mention – The UniFi UNAS Series – $199 to $799

SPECS: Quad core ARM Cortex A55 or A57 at 1.7 to 2.0 GHz – 4 to 16 GB LPDDR4 – 2 to 8 x 3.5″ SATA bays – 1 x 2.5 GbE RJ45 / 1 x 1 GbE RJ45 / up to 3 x 10 GbE (RJ45 and SFP+) – 0 or 2 x M.2 NVMe SSD slots for cache (depending on model).

While not a single flagship unit, UniFi’s expanded UNAS NAS range in 2025 merits an honorary mention as a platform level development. Moving from a single NAS offering in 2024 to multiple UNAS models in 2025, UniFi shifted from dabbling in storage to positioning itself as a serious option for small business, UniFi centric home labs and integrators that want storage tightly aligned with existing UniFi networking and management.

The significance here is not an isolated specification or feature, but the fact that a major networking vendor is rapidly building out a NAS portfolio at a time when private data ownership, self hosted services and integrated stacks are becoming more important, adding competitive pressure on more established, slower moving NAS brands.

UNAS UNAS 2 – 2-Bay NAS – $199	UNAS UNAS Pro 8 – 8-Bay NAS – $799

#1 Aoostar WTR Max – $599-699

SPECS: AMD Ryzen 7 Pro 8845HS – up to 128 GB DDR5 ECC via 2 SODIMM slots – 6 x 3.5″/2.5″ SATA bays – 2 x 2.5 GbE RJ45 / 2 x 10 GbE SFP+ – 5 x M.2 2280 NVMe PCIe 4.0 slots.

The Aoostar WTR Max is a prebuilt, OS agnostic NAS chassis that stands out for its hardware density at its price point. It combines 6x hard drive bays with 4x M.2 NVMe slots, dual 10 GbE networking and an AMD server grade platform with ECC memory support in a compact enclosure that has been noted for effective cooling relative to its size. Rather than tying buyers to a proprietary operating system, it is intended to run third party NAS or server platforms, which gives it flexibility but also means any software integration and management experience depends on the OS the user chooses to deploy. Throughout 2025 it has frequently been in short supply, indicating sustained demand from home lab users and small operators who want near turnkey hardware with specifications that would be expensive to replicate via a fully DIY build.

What We Said in our June ’25 review HERE: The Aoostar WTR Max stands out as a rare blend of high storage density, advanced connectivity, and raw compute performance in a compact NAS form factor, making it well-suited for experienced users seeking a versatile, self-managed platform. With support for up to 11 drives—six SATA and five NVMe Gen 4—paired with an enterprise-grade Ryzen 7 PRO 8845HS CPU and ECC memory compatibility, the system offers workstation-class capabilities for storage-heavy workflows, including virtualization, multimedia processing, and hybrid file serving. Dual 10GbE SFP+ and dual 2.5GbE ports provide ample bandwidth for multi-user access or isolated subnet roles, while the OCuLink interface enables high-speed external expansion, compensating for the absence of a traditional PCIe slot. Additional benefits like a fully customizable LCD status display, low fan noise, and consistently low thermals under load reinforce the system’s value in 24/7 deployments.

However, the WTR Max does present some caveats—namely, internal NVMe cross-performance appears constrained by shared bandwidth, and the lack of an internal PCIe slot could be limiting for users requiring more conventional upgrade paths. The LCD panel’s configuration software also proved cumbersome, raising security flags and requiring manual IP client setup, which may deter less technically inclined users. Lastly, the use of an external 280W PSU—while effective—won’t appeal to those expecting internal power integration in a workstation-style chassis. Nonetheless, for users who value full control over their NAS stack and want to avoid restrictive ecosystems, the WTR Max delivers a rare combination of hardware freedom and scalability that few turnkey systems offer in this price and size category.

#2 Minisforum N5 NAS – $549-599

SPECS: AMD Ryzen 7 255 or AMD Ryzen AI 9 HX Pro 370 – up to 96 GB DDR5 (ECC on N5 Pro) – 5 x 3.5″/2.5″ SATA bays – 1 x 5 GbE RJ45 / 1 x 10 GbE RJ45 – 3 x M.2 NVMe slots (2 convertible to U.2, PCIe 4.0).

The Minisforum N5 is a compact 5-bay NAS that targets users who want preconfigured hardware with some workstation derived design features. It uses an x86 CPU in the same general class as the Aoostar WTR Max, paired with an internal storage module of 64 GB for the system volume, and is typically sold in the 599 to 699 USD range, with the separate Pro variant occupying a higher bracket. The chassis integrates a removable drive base section for easier maintenance, and the platform includes multi-gig networking up to 10 GbE and 5 GbE, a PCIe expansion slot and USB4 connectivity for additional bandwidth or external devices. Minisforum ships the N5 with its own NAS operating system to provide an immediate out of box experience, but the software is still relatively young and many buyers elect to overwrite the included module with a more established NAS or server OS. Throughout 2025, availability has been intermittent, reflecting a level of demand from home lab users who want higher specification NAS hardware without building entirely from individual components.

What we said in our July ’25 Review HERE:

The Minisforum N5 Pro is an impressive and highly versatile NAS platform that successfully combines the core strengths of a storage appliance with the capabilities of a compact, workstation-class server, making it suitable for demanding and varied use cases. Its defining features include a 12-core Ryzen AI 9 HX PRO 370 CPU with 24 threads and onboard AI acceleration up to 50 TOPS, support for up to 96GB of ECC-capable DDR5 memory for data integrity, and a hybrid storage architecture offering up to 144TB total capacity through a mix of five SATA bays and three NVMe/U.2 slots. Additional highlights such as ZFS file system support with snapshots, inline compression, and self-healing, along with high-speed networking via dual 10GbE and 5GbE ports, and expansion through PCIe Gen 4 ×16 and OCuLink interfaces, position it well beyond the capabilities of typical consumer NAS systems. The compact, fully metal chassis is easy to service and efficiently cooled, enabling continuous operation even under sustained virtual machine, AI, or media workloads.

At the same time, the bundled MinisCloud OS, while feature-rich with AI photo indexing, Docker support, and mobile integration, remains a work in progress, lacking some enterprise-grade polish, robust localization, and more advanced tools expected in mature NAS ecosystems. Minor drawbacks such as the external PSU, the thermally challenged pre-installed OS SSD, and the higher cost of the Pro variant relative to the standard N5 are important to weigh, particularly for users who may not fully utilize the Pro’s ECC and AI-specific advantages. For advanced users, homelab builders, and technical teams who require high compute density, flexible storage, and full control over their software stack, the N5 Pro delivers workstation-level performance and configurability in NAS form—offering one of the most forward-thinking and adaptable solutions available today in this segment.

#3 Beelink ME Mini N150 NAS – $209-299

SPECS: Intel N150 quad core Twin Lake SoC up to 3.6 GHz – 12 GB LPDDR5 (with 16 GB LPDDR5 variant announced) – 6 x M.2 2280 SSD bays – dual 2.5 GbE RJ45 / WiFi 6 – 6 x M.2 NVMe PCIe 3.0 slots (5 x1 / 1 x2, one slot also supporting SATA SSD).

The Beelink ME Mini N150 is an all flash, ultra compact NAS style platform built around 6x M.2 NVMe bays, an Intel N150 CPU and 12 to 16 GB of memory, aimed at low power home lab and edge storage roles. It typically ships in the 200 to 250 USD bracket depending on retailer and configuration, and includes a small amount of onboard eMMC storage intended for the operating system, with users commonly installing Linux distributions such as Ubuntu or other lightweight NAS platforms. Connectivity includes dual 2.5 GbE ports, making it suitable for multi gig networks despite its size, and its idle power draw with all slots populated has been measured in the sub 10 to 12 W range, which positions it as an efficient always on node. While comparable N150 based systems from GMKTEC and turnkey brands like TerraMaster arrived in the same period, the ME Mini gained wider attention in 2025 because its combination of price, power envelope and density is difficult to match via a conventional DIY build using standard motherboards and cases.

What we said in our June ’25 Review HERE:

The Beelink ME Mini NAS delivers an uncommon blend of size, functionality, and efficiency in a market segment often dominated by larger, louder, and less integrated alternatives. It is not designed to compete with traditional enterprise-grade NAS devices or modular, scalable solutions for prosumers. Instead, its strengths lie in targeting the needs of home users who want a quiet, energy-efficient storage solution that is easy to deploy, aesthetically unobtrusive, and capable of handling daily tasks such as media streaming, file backup, or soft routing. The inclusion of six M.2 NVMe SSD slots—paired with a Gen 3 x2 system slot—offers a rare level of expansion in such a small enclosure. The integration of an internal PSU, silent fan-assisted cooling, and a surprisingly effective thermal design are thoughtful touches that differentiate it from the majority of DIY NAS mini PCs.

That said, it is not without limitations. The memory is non-upgradable, thermal accumulation at the base suggests room for improvement, and bandwidth ceilings imposed by Gen 3 x1 lanes will constrain users who demand high parallel throughput. Still, for its price point—particularly when pre-order discounts are applied—the ME Mini offers significant value, especially when compared to ARM-based NAS solutions with similar or lower specifications. With bundled Crucial SSD options and support for a wide range of NAS operating systems, it positions itself as a ready-to-go platform for tech-savvy users wanting to avoid the assembly of a fully DIY system. Overall, while not a product for every use case, the Beelink ME Mini succeeds in its aim to be a compact, stylish, and capable home NAS.

#4 Lincplus Lincstation N2 – $399-449

SPECS: Intel N100 quad core up to 3.4 GHz – 16 GB LPDDR5 – 2 x 2.5″ SATA bays / 4 x M.2 NVMe bays (total 6 bays) – 1 x 10 GbE RJ45 – 4 x M.2 2280 NVMe SSD slots.

The Lincstation N2 is a compact prebuilt NAS positioned primarily on value, combining an Intel N100 quad core CPU, 16 GB of non upgradable memory and 10 GbE networking in a small chassis. Storage is split between 4x M.2 NVMe bays and 2x 2.5 inch SATA bays, giving a mix of high speed solid state and more conventional, higher capacity drives, with visible status LEDs on the exterior. Typical street pricing in 2025 has been around 400 to 450 USD depending on tax and discounts, but its effective cost is reduced further by the inclusion of an Unraid license, which separately represents a non trivial software expense and is pre supported via a USB loader for straightforward deployment. While the N100 CPU and PCIe lane distribution place it below some competing platforms in raw performance, the combination of 10 GbE, mixed media bays, bundled software and small footprint makes it a distinct option for users who prioritise overall throughput and licensing value rather than maximum compute power.

What we said in our Jan ’25 Review HERE:

The Lincstation N2 NAS is a solid upgrade over its predecessor, the N1, offering better connectivity, improved cooling, and more efficient hardware. The inclusion of 10GbE networking makes it a more appealing option for users who require higher data transfer speeds, and the passive and active cooling improvements ensure better thermal regulation under sustained workloads. With support for four M.2 NVMe SSDs and two SATA SSDs, the N2 provides flexible storage options, allowing users to build a high-speed, all-flash NAS setup. The Intel N100 processor and 16GB LPDDR5 memory deliver decent performance for most home and small business NAS applications, but the non-upgradeable memory may be a limiting factor for more demanding users. The compact, efficient design makes it an ideal NAS for those looking for a balance between power efficiency and performance.

That being said, the N2 does have a few drawbacks that may impact users looking for greater expandability. The lack of PCIe expansion slots means users cannot add additional NICs or storage controllers, making it less versatile compared to some competing NAS solutions. Additionally, while the 10GbE port is a significant upgrade, it is limited by PCIe bandwidth constraints, meaning users may not be able to fully utilize its maximum throughput in all scenarios. The USB connectivity options are decent, but having only one high-speed USB-C 10Gbps port may feel restrictive for those wanting multiple fast external connections. Furthermore, the reliance on a barrel-type power connector instead of USB-C is another missed opportunity for modernization.

Overall, the Lincstation N2 NAS remains a good choice for UnRAID users looking for an affordable, high-speed, all-flash NAS solution. It provides great energy efficiency, a streamlined setup process, and a solid mix of connectivity options. While it lacks some scalability features, for most home and small business users, it offers a compelling blend of performance, efficiency, and ease of use. If Lincplus continues refining their NAS lineup, future iterations with more robust networking, storage expandability, and minor refinements to cooling and connectivity could make it a standout competitor in the small NAS market.

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.

Minisforum MS-02 – Internal Hardware

The Minisforum MS-02 Ultra is built around Intel’s Arrow Lake-HX platform, with the Core Ultra 9 285HX serving as its central processor. This 24-core CPU combines eight performance cores and sixteen efficiency cores, reaching up to 5.5 GHz while maintaining a 140 W thermal design power. It incorporates an integrated Intel Arc GPU with four Xe cores and an NPU capable of up to 13 TOPS for AI acceleration. The CPU provides 24 PCIe lanes in total, which are distributed among the system’s multiple expansion and storage options.

Memory capacity is one of the most notable upgrades over its predecessor. The MS-02 Ultra offers four DDR5 SO-DIMM slots, supporting up to 256 GB of 4800 MHz memory, with full ECC functionality for stability in continuous workloads. Two modules are located on the CPU side of the board, and two on the reverse, optimizing thermal spacing and service access. This capacity places it closer to entry-level server configurations than typical mini PCs, reinforcing its suitability for virtualization or compute-heavy tasks.

Storage expansion is handled through four M.2 2280 NVMe slots, each supporting PCIe 4.0 ×4 bandwidth. Combined, these slots can accommodate up to 16 TB of SSD storage. The system’s slide-out chassis design allows quick installation or replacement of drives, simplifying maintenance. Minisforum has also introduced a small debug LED and clear CMOS button on the board, indicating that the model is targeted toward users familiar with system-level configuration and troubleshooting.

Expansion flexibility extends far beyond most small form factor workstations. The system includes three PCIe slots: one PCIe 5.0 ×16, one PCIe 4.0 ×16 (often occupied by a 25 GbE NIC in standard configurations), and one PCIe 4.0 ×4. The top slot can host dual-slot desktop graphics cards, drawing up to 140 W through an included 8-pin auxiliary connector. This allows for the addition of mid-range GPUs such as the NVIDIA RTX 4000 SFF Ada or workstation accelerators, while still retaining physical compactness.

Power delivery is managed through a built-in 350 W Flex PSU that eliminates the need for an external brick. This internal supply was a deliberate shift from the MS-01’s external adapter and helps sustain higher CPU and GPU draw without additional clutter. The unit supports 100–240 V AC input, giving it universal deployment flexibility for both workstation and light server scenarios.

Minisforum MS-02 – Ports and Connections

The Minisforum MS-02 Ultra includes a broad range of connectivity options intended to support both workstation and server workloads. Front access is optimized for frequent use, featuring two USB4 Version 2.0 Type-C ports offering 80 Gbps bandwidth each, a 10 Gbps USB Type-A port, a 3.5 mm audio combo jack, and the system power button. These front USB4 v2 ports also support DisplayPort Alternate Mode and Power Delivery up to 15 W per port, making them suitable for high-speed data transfer or direct monitor output without additional adapters.

The rear I/O layout is designed for permanent peripheral and network connections. It includes a third USB4 Type-C port rated at 40 Gbps, three USB 3.2 Gen 2 Type-A ports at 10 Gbps each, and a single HDMI 2.1 output supporting up to 8K at 60 Hz or 4K at 120 Hz. For network communication, the MS-02 Ultra integrates four ports in total: two 25 GbE SFP28, one 10 GbE RJ-45, and one 2.5 GbE RJ-45. The 2.5 GbE interface uses Intel’s i226-LM controller and supports vPro remote management for BIOS-level administration, which is beneficial for enterprise or headless operation.

Wireless connectivity is provided by an M.2 2230 E-Key slot supporting Wi-Fi 7 and Bluetooth 5.4 modules, enabling flexible configuration for wireless networks or peripheral pairing. The combination of USB4 v2, multiple Ethernet options, and RDMA capability positions the MS-02 Ultra as a system ready for both high-performance workstation setups and compact server deployments. Its port layout, with both front and rear accessibility, ensures straightforward use in horizontal or vertical orientations.

Minisforum MS-02 – Cooling and Temperature Management

The cooling system of the Minisforum MS-02 Ultra is designed to manage sustained high thermal loads while maintaining compact dimensions. The chassis follows a front-intake and rear-exhaust airflow pattern, similar to rackmount servers. A six-heatpipe radiator combined with phase-change material (PCM) ensures efficient heat dissipation from both the CPU and expansion slots. This design enables the system to maintain stable operation at a 140 W CPU TDP, even when fully populated with PCIe cards and NVMe storage. Airflow direction also varies depending on the unit’s orientation, with side-mounted intakes feeding the expansion slots and rear vents handling exhaust when the unit is placed horizontally or vertically.

The internal layout is structured to prevent thermal overlap between major components. The CPU and memory modules are cooled through a direct-contact heat spreader, while GPU and add-in cards draw intake air from the left side and expel it from the right or top, depending on placement. The inclusion of an internal 350 W Flex PSU was balanced with this design, ensuring sufficient clearance and airflow. This approach allows the MS-02 Ultra to sustain continuous high-load performance without external cooling solutions or the noise levels typical of larger tower workstations.

Minisforum MS-02 Ultra Workstation – Worth waiting for?

The Minisforum MS-02 Ultra represents a substantial progression from the original MS-01 workstation, addressing nearly every limitation of its predecessor. The earlier model, released in 2023, gained attention for integrating desktop-class performance into a small form factor but was constrained by its single-slot PCIe design, limited memory capacity, and reliance on an external power brick. The MS-02 Ultra resolves these issues with four DDR5 SO-DIMM slots supporting up to 256 GB ECC memory, a dual-slot PCIe 5.0 ×16 slot for graphics or accelerator cards, and a fully internal 350 W Flex PSU. These refinements, along with the addition of 25 GbE networking and USB4 v2 connectivity, elevate the system into a new category that bridges high-end workstation and compact enterprise server design.

Performance and versatility are at the center of this system’s concept. The inclusion of a 24-core Intel Core Ultra 9 285HX CPU and up to four PCIe 4.0 NVMe drives positions it for continuous workloads such as virtualization, software development, or AI inference without the thermal or structural compromises typical of small PCs. Minisforum’s decision to adopt ECC memory and RDMA-capable networking also underlines a shift toward reliability and professional usage scenarios rather than enthusiast or gaming audiences.

In terms of market placement, pricing has yet to be confirmed, but early indications suggest the MS-02 Ultra will likely start around $1,500, with higher configurations approaching or exceeding $2,000 depending on memory, storage, and NIC options. This aligns it with compact workstations like the ASRock DeskMeet X600 and high-end mini servers from OEM integrators, though the Minisforum model’s density and component flexibility set it apart. Overall, the MS-02 Ultra shows how far the brand’s SFF engineering has advanced since the MS-01, turning a well-liked prototype concept into a fully realized professional-grade workstation built for sustained heavy use.
