The Beelink ME Pro NAS – Should You Buy

After the surprising hit that was the Beelink ME Mini NAS in 2025, a lot of users were looking forward to seeing what the brand would do next in the NAS space. In January 2026, the brand responded with the launch of the Beelink ME Pro: an Intel N95/N150 powered system with DDR5 memory, 5GbE plus 2.5GbE connectivity, 2 SATA HDD bays, 3 M.2 NVMe bays, and one of the smallest physical footprints in this device class that I have seen. I have a full detailed review in progress on the ME Pro, but even after several days of use, several pros and cons have already emerged that may influence whether this is the right purchase for a homelab. While the review comes together, this article will outline the good, the bad, and the weird aspects of the Beelink ME Pro NAS.

Bonus Point: Really Nice Logistics Design

This is a minor point, but it is worth noting how the ME Pro arrives. The chassis box is unusually small for a 2-bay NAS, and at first glance it can look like the packaging contains little more than the unit itself. In practice, the accessory items are stored inside the drive bracket area in small internal boxes, which helps avoid loose parts moving around in transit and reduces wasted packaging volume.

The device also arrives with the M.2 thermal pads already positioned in place, so the initial storage installation process is more direct. It is not a major buying factor, but it is a practical packaging decision that avoids the excessive empty space and material waste that is common in this product category.

Reasons you Should Buy the Beelink ME Pro NAS

The ME Pro is positioned as a compact, high-connectivity 2-bay NAS that also provides NVMe expansion and local display capability, with hardware aimed at users who want more than basic file serving in a small footprint. It combines dual-port networking, integrated wireless connectivity, and multiple internal storage options in a chassis designed for straightforward access and cleaning, while also introducing a motherboard drawer concept that Beelink claims will support future platform upgrades. If those priorities match your setup goals, the ME Pro has several practical advantages that can justify its price and design choices.

#1 Man alive – this 2 Bay NAS is TINY!

The ME Pro’s most immediate differentiator is its physical footprint. The chassis measures 166 x 121 x 112mm and uses an all metal unibody design, which is notably smaller than most 2-bay NAS boxes that also include NVMe storage and dual network ports. In person it reads closer to a compact mini PC enclosure than a traditional NAS, and that difference matters if you are placing it on a crowded desk, a media shelf, or anywhere you are trying to keep cabling and hardware out of the way.

That compactness is not just cosmetic, it directly shapes how the hardware is arranged and how it feels to work with. Storage bays, the NVMe area, networking, and the cooling hardware are densely packed, so clearances are tight and the device is designed around precision fit rather than roomy access. The upside is that it is easy to place in small spaces without needing the usual NAS sized footprint. The tradeoff is that installations and maintenance are likely to feel more constrained than they would on a larger, more conventional 2-bay enclosure.

#2 Arrives with 5GbE and WiFi6, when everyone else is still on 2.5GbE

On networking, the ME Pro ships with 2 wired Ethernet ports and integrated wireless. The wired setup is a 5GbE Realtek RTL8126 port alongside a 2.5GbE Intel i226-V port, and the unit also includes WiFi 6 plus Bluetooth 5.4. For a compact 2-bay NAS, that is a broader mix of connectivity than the many systems that still top out at dual 2.5GbE, and it gives you more options for how the device fits into an existing home or small office network.

In practical terms, this provides flexibility rather than guaranteeing a specific performance outcome. A 5GbE port can be useful for faster transfers if you already have compatible switching or direct attach options, while the 2.5GbE port can serve as a secondary link for a different subnet, failover, or a separate device path depending on the OS and network configuration you choose. WiFi 6 is not a replacement for wired networking in a NAS role, but it can be relevant for temporary placement, initial setup, or use cases where running a cable is not straightforward, and the manual indicates the antenna is integrated into the front panel design rather than using an external antenna.

#3 Maintenance and Internal Access is a work of art!

The ME Pro is built around user access rather than treating the internals as a sealed appliance. The manual’s process is simple: remove the magnetic cooling mesh cover, unscrew and pull out the hard drive bracket, and use the bottom access panel to reach the M.2 slots. A screwdriver is stored in the base under a silicone pad, so the tool required for basic access is physically included with the device. The ports and recovery related features also acknowledge user servicing, with items like a reset hole and a CLR CMOS function shown in the manual.

In day to day handling, the layout is designed to slide out and reassemble in a specific order, and it generally supports the idea of quick cleaning and drive installation without full disassembly. At the same time, access relies on small screws and tight tolerances, so it is not a tool-less experience. In your first impressions, the mechanism for sliding the internal assembly out felt solid and precisely aligned, but you also noted that the included tool is very small and can be fiddly to use. The result is a design that prioritizes compact service access, but still expects careful handling during installation and maintenance.

#4 Great Base Memory Quantity at a time when RAM costs are BONKERS

From the start, the ME Pro is configured with either 12GB LPDDR5 4800MHz on the N95 models or 16GB LPDDR5 4800MHz on the N150 models, rather than shipping with a minimal memory pool that immediately pushes users toward an upgrade. In practical NAS use, that baseline capacity is relevant because it can influence how comfortably the system handles common add-ons such as containers, light virtualization, background indexing, and multiple concurrent services, depending on the operating system and workload. It also reduces the likelihood that memory becomes the first immediate bottleneck for typical home and small office setups.

The tradeoff is that this approach is linked to the way the memory is implemented. In your inspection of the unit, you noted there is no SO-DIMM slot and the RAM appears soldered to the board, which means users are effectively choosing their memory tier at purchase rather than treating it as a later upgrade (more on that in a bit). This makes the initial configuration choice more important, especially for buyers who already know they will run heavier applications or multiple VMs over time.

#5 Genuinely unique modularisation and upgradability in a pre-built solution, which I have ever seen

The ME Pro’s most unusual design claim is the swappable modular motherboard. Beelink markets the system as supporting interchangeable boards across Intel, AMD, and ARM options, using a drawer style layout intended to let the main compute board slide out rather than being permanently fixed inside the chassis. The product page frames this as a way to avoid replacing the entire enclosure when you want a different CPU platform, and instead treat the chassis, drive housing, and general structure as the long-term part of the purchase.

In practical terms, this concept will only matter if Beelink actually sells the alternative boards at sensible pricing and maintains availability over time, but the physical architecture appears to be built around the idea. Your first look showed a clear internal separation between the board assembly and the rest of the enclosure, and you also observed hints of planned scale-up hardware, such as layout markings that suggest different future storage or platform variants. For buyers who like the idea of extending a system’s usable life without a full rebuild, the ME Pro is one of the few pre-built NAS style devices currently trying to formalize that upgrade path rather than leaving it to a full case swap.

Reasons You Might Want to Skip the Beelink ME Pro NAS

The ME Pro’s compact design and connectivity focused feature set come with tradeoffs that will matter to some buyers more than others. Several of the core choices are linked together, meaning you get the small chassis, the storage density, and the modular drawer approach, but you also accept limits around upgrades, physical handling, and how the platform is configured from the factory. This is not a device where every part is meant to be user replaceable or easily swapped in the way a DIY small form factor build would be.

It is also worth treating the launch configuration and roadmap as part of the buying decision. The product is being introduced with very similar Intel CPU options and fixed memory tiers, while the company is already pointing toward future AMD and ARM variants and possible expanded layouts. For some buyers, that is a reason to wait until the wider range exists and the upgrade parts are actually available. For others, the current design constraints are enough to prefer a more conventional 2-bay NAS that is larger, simpler to work on, and has clearer long-term upgrade paths.

The RAM is FIXED (i.e cannot be upgraded or changed)!!!

The ME Pro uses LPDDR5 memory (12GB on the N95 models, 16GB on the N150 models), and based on the internal layout you inspected, there is no SO-DIMM slot for user upgrades. In other words, the memory appears to be soldered to the motherboard rather than installed as a replaceable module. That makes the initial purchase configuration more important than on many small NAS builds where memory can be upgraded later as needs change.

The practical impact shows up when your usage grows beyond basic file storage. If you plan to run multiple containers, heavier indexing tasks, or virtual machines, memory headroom can become a limiting factor long before CPU or network does, depending on the OS and services you deploy. With this platform, there is no simple path to increase RAM after purchase, so anyone unsure about future requirements may prefer a system with upgradeable memory, or may want to treat the 16GB model as the safer long-term option by default.

The design is so, so very tight!

The ME Pro’s small enclosure is achieved through very tight internal tolerances. That is visible in how the drive bracket, motherboard drawer area, and storage zones are packed together, and it influences the overall experience during installation and servicing. The system relies on screw mounting for drives rather than a click-in tray approach, and while the manual provides clear steps, the process assumes careful alignment rather than quick, tool-less handling. This level of precision fit is likely part of how Beelink is trying to control airflow and improve thermal transfer in a compact space, and it also aligns with their noise and vibration messaging around tightened mounting and silicone dampening.

In the first impressions, that tightness showed up most clearly when inserting and removing components. Slotting the hard drive bracket and drives could feel rough at times, with very little clearance to work with, and the internal assembly can require a firmer push to seat correctly. Even if the compact fit is helping with heat dissipation and vibration control, it remains a very tight build, and it is less forgiving if you are frequently swapping drives, testing different storage combinations, or repeatedly opening the chassis. The end result is a device that looks clean and flush when assembled, but can feel constrained during hands-on work compared with a larger enclosure with more physical margin.

Launching the N95 version and N150 version was an odd choice (i.e very similar processors)

At launch, the ME Pro is offered in N95 and N150 variants, and on paper these CPUs sit very close to each other. Both are 4-core, 4-thread Intel N-series parts with 6MB cache, and the headline frequency difference is modest: up to 3.4GHz on the N95 and up to 3.6GHz on the N150. For many NAS workloads that are constrained by storage or network throughput rather than CPU, this kind of gap may not translate into a clearly different experience, especially once real world thermal and power limits are applied.

This tight spacing makes the product stack less clear than it could be, because the pricing difference between the entry and higher tier configurations is not simply paying for a meaningfully different platform. In practice, buyers are also paying for the memory and SSD tier attached to each CPU option, and in your case the non-upgradeable memory makes that choice more permanent. If the goal is to segment the lineup, the N95 and N150 pairing may feel like a small step that leaves some users waiting for a more distinct higher performance option rather than choosing between two closely related CPUs. Given the noise that Beelink has made about this expanding range, that only further encourages some users who think these CPUs a little timid, to remain on the fence a bit longer….

There are other CPU/Architecture versions coming

As mentioned, Beelink is already signalling that the ME Pro chassis is intended to outlive the initial Intel configurations. The official product messaging highlights a swappable modular motherboard concept and explicitly references future boards beyond the current Intel N-series options, including AMD and ARM. In your first look, you also noted visible hints inside the unit that suggest the internal layout has been planned with other variants in mind, rather than being a one-off design limited to the launch hardware.

For buyers, this creates a timing question. If those alternative boards and models arrive soon, they may offer clearer performance separation, different feature priorities, or a better match for specific workloads. At the same time, the current purchase decision depends on what is available today, not what is promised, and the value of the modular approach only becomes real once the upgrade boards can actually be bought at reasonable pricing. Until the roadmap becomes a shipping product line, some users may prefer to wait, while others will simply evaluate the current N95 and N150 models on their own merits.

Mixed M.2 Speeds at PCIe 3.0 x2 and PCIe 3.0 x1? Was 10GbE and uniform lanes discussed instead?

The ME Pro’s 3 M.2 NVMe slots are not equal. Slot 1 is PCIe 3.0 x2, while slots 2 and 3 are PCIe 3.0 x1, and the manual specifically recommends using slot 1 for the system drive because it is the fastest slot. In practical terms, this creates a tiered NVMe layout where one drive has higher potential bandwidth than the other 2, which can influence how you plan cache, containers, VM storage, or scratch workloads. It also means peak NVMe performance depends heavily on which slot you choose, not just the SSD you buy.

That design choice raises an obvious tradeoff question: whether the platform would have been better served by a different allocation, such as keeping all 3 M.2 slots at PCIe 3.0 x1 in exchange for other connectivity, or prioritizing a different network tier such as 10GbE (though arguably, it might well have to sit at 3×1 and potentially be bottlenecked to 800-900MB/s, unless that lowered the m.2 to x2 bays). The ME Pro already includes 5GbE plus 2.5GbE, so the networking is not low end, but the mixed NVMe lane widths still make the storage side feel uneven by design. For a NAS focused build, the practical impact will depend on real testing: whether the internal topology causes contention under mixed loads, and whether the faster slot meaningfully benefits common tasks once network and SATA throughput are considered.

Conclusion & Verdict – Should You Buy the Beelink ME Pro NAS?

The Beelink ME Pro is a compact 2-bay NAS platform that combines SATA storage with 3 M.2 NVMe slots, dual wired networking, and integrated wireless in an enclosure that prioritizes density and internal access. It also introduces a modular motherboard drawer concept that, if supported with real upgrade boards over time, could change how long the chassis remains useful compared with typical pre-built NAS systems. As a hardware package, it is aimed at users who want high connectivity and mixed storage options without moving to a larger box.

At the same time, several of its main limitations are set at purchase and cannot be easily changed later. The memory appears fixed, the internal fit is very tight during drive and bracket handling, and the launch CPU options are closely spaced rather than clearly separated performance tiers. The NVMe layout is also mixed speed by design, which affects how you should plan drive placement and workloads. Whether these tradeoffs are acceptable depends largely on how much you value the enclosure size, the network ports, and the promised modular roadmap versus the more conventional upgrade flexibility of larger or more established NAS designs.

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. For additional flexibility, the system supports online RAID migration and expansion, meaning users can start small and scale capacity over time without data loss.

Beyond local storage, the device integrates directly with TerraMaster’s CloudSync service, which connects to providers like Google Drive, OneDrive, Dropbox, and Baidu Cloud. Hybrid storage configurations allow partial replication or tiered backup between the NAS and the cloud, offering an extra level of redundancy for professional workflows. External connectivity through USB 3.2 ports also supports direct backups to DAS enclosures or portable drives. Altogether, the F4-425 Plus’s design emphasizes efficient cooling, solid construction, and versatile storage architecture, making it a flexible foundation for both data-heavy projects and long-term digital archiving.

The Terramaster F4-425 PLUS NAS Review – Internal Hardware

Internally, the TerraMaster F4-425 Plus is structured around Intel’s N150 processor, a 4-core, 4-thread CPU from the Twin Lake generation. Built on a 6W TDP architecture, this chip delivers a significant efficiency advantage over the previous N5095-based systems while offering a higher burst clock of up to 3.6 GHz. The CPU integrates Intel UHD Graphics, allowing 4K hardware decoding for H.264, H.265, VC-1, and MPEG-4, which is particularly beneficial for Plex, Emby, or Jellyfin users who want native transcoding without GPU add-ons.

This combination makes the system viable not only as a file server but also as a local multimedia hub, capable of decoding and streaming 4K video at up to 60 frames per second. Despite being a low-power chip, its instruction set includes AES-NI hardware encryption, ensuring efficient data security without notable throughput loss when encryption is enabled.

The system’s memory architecture uses a single DDR5 SO-DIMM slot, populated with a 16GB non-ECC module by default and expandable up to 32GB. The adoption of DDR5 over DDR4 marks a generational improvement in bandwidth and latency, leading to faster multitasking, smoother virtualization performance, and reduced overhead when handling multiple users or services. The memory module is non-ECC but benefits from on-die error correction at the hardware level, offering stability improvements over standard DDR4 implementations. This approach aligns with the unit’s target demographic of small offices, creators, and advanced home users who want server-grade responsiveness without enterprise complexity.

Storage connectivity within the system is distributed between four SATA III 6Gb/s interfaces managed by an ASMedia controller and three PCIe 3.0 x1 lanes dedicated to M.2 NVMe SSDs. This configuration ensures balanced throughput for simultaneous HDD and SSD activity. Internally, the layout is straightforward, providing easy access to both the memory slot and M.2 bays via the removable top panel. 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.

Terramaster F4-425 PLUS & F2-425 PLUS NAS Hardware Specifications

Terramaster’s F2-425 PLUS and F4-425 PLUS NAS units share a unified hardware architecture centered on Intel’s N150 processor, part of the Twin Lake family. This 4-core, 4-thread CPU operates at a base clock of 1.0 GHz and boosts up to 3.6 GHz, with integrated Intel UHD graphics that support hardware acceleration for 4K and 8K video decoding. While the N150 is not a high-power processor by desktop standards, it provides excellent balance between performance and efficiency for NAS workloads such as Plex or Jellyfin media streaming, file indexing, and lightweight virtualization. The use of this chip also aligns Terramaster’s lineup with newer offerings from competitors who have adopted similar architectures in their 2025 models.

The memory configuration has moved to DDR5, marking a notable generational shift from the DDR4 modules used in previous Terramaster systems. The F2-425 PLUS includes 8 GB of DDR5, while the F4-425 PLUS doubles this to 16 GB, both expandable up to 32 GB. 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.

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.
