Choosing a 4-bay NAS enclosure means weighing more than how many drives fit. Network speed, processor headroom, memory, software features, and ease of setup all shape whether a system suits home backups or a heavier multi-user workload. My leading picks are the UGREEN NAS DXP4800 Pro for its 10GbE connection and strong compute options, the TerraMaster F4-424 Pro for its included 32GB of memory, and the QNAP TS-464 for dual 2.5GbE networking with two NVMe slots.

Those strengths come with different compromises. The UGREEN DXP4800 Pro offers the broadest network and memory ceiling, but advanced functions may take more setup. TerraMaster supplies generous memory out of the box, though it cannot be upgraded. QNAP gives buyers flexible caching and storage expansion, while the simpler UGREEN DH4300 Plus focuses on household media and backups rather than virtual machines. All four are sold without drives, so I compare them as enclosures and systems, not as ready-to-use storage bundles.

More Details on Our Top Picks
UGREEN NAS DXP4800 Pro 4-Bay Network Attached Storage
I rank the UGREEN DXP4800 Pro first because it pairs a strong processor with the most ambitious network setup here: 10GbE and 2.5GbE ports. That combination is suited to large file transfers and busy workflows, provided the rest of the network can make use of 10GbE. Its Intel Core i3-1315U, 8GB of DDR5 memory expandable to 96GB, and support for Docker and virtual machines give it a broader workload range than the home-oriented DH4300 Plus.
Expansion is another advantage. The unit has four drive bays, two PCIe 4.0 M.2 slots, and a stated maximum capacity of 144TB. That gives buyers multiple storage-planning options, while tool-free trays make routine drive installation less fussy. The UGOS Pro system also includes on-device AI photo organization, which may help households manage growing libraries without relying solely on cloud services.
The tradeoff is that capability does not equal effortless setup. UGREEN notes that some advanced features may require configuration, so a buyer who only wants plug-in backups may find the DXP4800 Pro more system than necessary. It also ships without drives, and its two-year warranty is shorter than the QNAP TS-464’s three-year coverage. Compared with the TerraMaster F4-424 Pro, it begins with less memory but offers a far higher stated upgrade ceiling and faster networking. I place it first for buyers who value that combination over a simpler initial setup.
Pros:- 10GbE and 2.5GbE ports support varied high-speed network setups.
- Memory can expand from 8GB to 96GB DDR5.
- Supports Docker, virtual machines, and two PCIe 4.0 M.2 slots.
- Tool-free trays and stated support for up to 144TB aid flexible storage planning.
Cons:- Ships without drives, so storage must be sourced separately.
- Some advanced features may call for setup and configuration.
- Its two-year warranty is shorter than QNAP’s stated three-year warranty.
Best for: Home labs, small offices, and advanced home users who want 10GbE, Docker or virtual-machine support, and substantial memory expansion.
Not ideal for: Buyers seeking a basic backup appliance, a drive-included package, or the longest stated warranty among these four models.
- Drive bays:4
- Processor:Intel Core i3-1315U, 6 cores and 8 threads, up to 4.5GHz
- Memory:8GB DDR5, expandable to 96GB
- Network:10GbE and 2.5GbE
- M.2 slots:2 PCIe 4.0
- Maximum stated capacity:144TB
- RAID modes:0, 1, 5, 10
- Operating system:UGOS Pro
- Warranty:2 years
Our verdict“I recommend the DXP4800 Pro for buyers who can use its 10GbE link and want the broadest upgrade path in this group.”
TerraMaster F4-424 Pro 4-Bay NAS Enclosure, Intel Core i3-N305, 32GB DDR5, Diskless
The TerraMaster F4-424 Pro takes a different route from the DXP4800 Pro: rather than starting with expandable memory, it supplies 32GB of DDR5 from the outset. Its eight-core Intel Core i3-N305 and integrated graphics make it a capable foundation for concurrent services, backup applications, and other demanding NAS tasks. Buyers who prefer a substantial memory allocation without planning an upgrade may find this more appealing than the UGREEN DXP4800 Pro’s 8GB starting point.
Its four bays are joined by dual 2.5GbE ports and two M.2 NVMe slots. That is a useful mix for a NAS focused on local storage and networked access, though it does not match the DXP4800 Pro’s 10GbE option. RAID choices include 0, 1, 5, 6, and 10, alongside JBOD, Single, and TRAID. Tool-free drive installation, noise-reducing panels, and shock absorption are practical touches for a unit that may run continuously in a home or small work space.
The key limitation is fixed memory: its 32GB is non-upgradable. That gives it a generous starting point but no way to scale beyond it, unlike the UGREEN DXP4800 Pro. The supplied details also describe it as diskless, and its two-year warranty matches UGREEN rather than QNAP’s longer stated coverage. I place it second because its hardware is compelling for multitasking, but network speed and memory flexibility give the DXP4800 Pro a wider ceiling.
Pros:- Eight-core Intel Core i3-N305 processor and 32GB DDR5 memory.
- Two 2.5GbE ports and two M.2 NVMe slots.
- Broad stated RAID support, including RAID 6 and TRAID.
- Tool-free drive installation with noise-reducing and shock-absorbing features.
Cons:- Memory is non-ECC and cannot be upgraded.
- Network ports top out at 2.5GbE, unlike the DXP4800 Pro’s 10GbE option.
- Diskless configuration means drives must be purchased separately.
Best for: Buyers who want a powerful processor and 32GB of memory installed from the start for multiple services or intensive multitasking.
Not ideal for: Users who need 10GbE networking, want to upgrade RAM later, or would rather begin with a smaller memory configuration.
- Drive bays:4
- Processor:Intel Core i3-N305, 8 cores and 8 threads, up to 3.8GHz
- Memory:32GB DDR5 4800MHz, non-ECC and non-upgradable
- Ethernet:2 × 2.5GbE
- M.2 slots:2 × M.2 NVMe
- USB:2 × USB 3.2 10Gbps
- RAID support:RAID 0/1/5/6/10, JBOD, Single, TRAID
- Drive configuration:Diskless
- Warranty:2 years
Our verdict“I would choose the F4-424 Pro over the QNAP when 32GB of fixed memory matters more than 10GbE or a memory upgrade path.”
QNAP TS-464-8G-US 4-Bay Desktop NAS
The QNAP TS-464 is my balanced pick for buyers who want useful expansion without moving into the DXP4800 Pro’s more demanding 10GbE setup. Its Intel quad-core processor and 8GB of DDR4 memory can be upgraded to 16GB, while dual 2.5GbE ports allow faster local transfers than a single gigabit connection when the network supports it. Hardware-assisted encryption adds a layer of processing support for protected data workflows.
Two PCIe Gen3 x2 NVMe slots set the QNAP apart from a basic four-bay enclosure. They can be used for caching or SSD storage, giving buyers another way to tune access to frequently used files. Compared with the TerraMaster F4-424 Pro, the TS-464 starts with less memory and a less powerful stated processor, but it offers upgradeable RAM and a three-year warranty. Compared with the DH4300 Plus, it is a stronger choice for someone who wants more networking flexibility and explicit NVMe expansion.
Its limits are clear: this is a diskless system, so drive selection and RAID setup are still part of the purchase. The memory ceiling of 16GB is modest beside the DXP4800 Pro’s 96GB expansion limit, and its 2.5GbE connections do not offer the UGREEN model’s 10GbE port. I rank it third because it provides a well-rounded feature set and longer stated warranty, but it is not the pick for the highest compute ceiling or fastest wired link in this group.
Pros:- Dual 2.5GbE ports support faster local networking.
- Two NVMe slots can serve caching or SSD storage pools.
- Memory expands from 8GB to 16GB.
- Hardware-assisted encryption and a stated three-year warranty.
Cons:- Diskless configuration requires separate drive purchases.
- Memory expansion stops at 16GB, below the UGREEN DXP4800 Pro’s stated ceiling.
- No 10GbE port is listed.
Best for: Home users and small teams who want dual 2.5GbE, NVMe caching or SSD options, hardware-assisted encryption, and a three-year warranty.
Not ideal for: Buyers seeking 10GbE networking, very high memory capacity, or a NAS that arrives with drives installed.
- Drive bays:4
- Processor:Intel Celeron N5105/N5095 quad-core, up to 2.9GHz
- Memory:8GB DDR4, supports up to 16GB
- Network:2 × 2.5GbE
- M.2 slots:2 × PCIe Gen3 x2 NVMe
- Drive interface:SATA 6Gb/s
- Maximum USB transfer speed:10Gb/s
- Enclosure material:Metal
- Warranty:3 years
Our verdict“I recommend the TS-464 for a balanced, expandable home or small-office NAS when dual 2.5GbE is enough.”
UGREEN NAS DH4300 Plus 4-Bay Network Attached Storage
The UGREEN DH4300 Plus is the least workstation-oriented option here, and that is its point. It targets private home storage, photo backups, and media access across computers, phones, tablets, and smart TVs. Its 8GB LPDDR4X memory, 2.5GbE port, 4K HDMI output, and AI photo organization cover common household jobs without matching the DXP4800 Pro’s processor and connection range. Docker support adds some room for extra services, but virtual machines are not supported.
For a household that wants one central place for files and media, the platform’s cross-device access and photo tools may be more relevant than a high-core-count processor. The stated maximum capacity is 128TB, and the product supports remote access as well as automatic backups. Compared with the QNAP TS-464, the DH4300 Plus offers HDMI output and a more home-media-oriented feature list, but the QNAP has dual 2.5GbE ports and two explicitly specified NVMe slots. Against the DXP4800 Pro, the DH4300 Plus is simpler but lacks 10GbE and virtual-machine support.
It is not a wireless NAS: the unit requires a wired Ethernet connection and does not support Wi-Fi. It is also diskless, and the supplied specifications do not list an expandable memory path. Buyers planning a home lab or a multi-service server should choose one of the higher-ranked systems instead. I place it fourth because its household focus is useful, but its narrower networking and compute limits make it less adaptable as workloads grow.
Pros:- AI photo organization includes search, recognition, and duplicate removal.
- Supports 2.5GbE networking and 4K HDMI output.
- Provides private storage, automatic backups, and remote access across common devices.
- Docker support adds some flexibility for home services.
Cons:- Drives are not included.
- No Wi-Fi support; a wired Ethernet connection is required.
- Virtual machines are not supported.
Best for: Households seeking a central destination for photo backups, private media storage, remote access, and 4K HDMI output.
Not ideal for: Home-lab users, buyers who need virtual machines or Wi-Fi, and anyone seeking dual 2.5GbE or 10GbE networking.
- Drive bays:4
- Maximum stated capacity:128TB
- Memory:8GB LPDDR4X
- Network:2.5GbE Ethernet; wired connection only
- Drive interface:SATA
- Drive inclusion:Diskless; HDDs and SSDs not included
- Virtual machines:Not supported
- Docker:Supported
- Video output:4K HDMI
Our verdict“I would choose the DH4300 Plus for household backup and media use, not for a NAS expected to run virtual machines or scale into a home lab.”
How We Picked
I ranked these four-bay enclosures by how well their hardware and stated features match distinct storage jobs, rather than treating every model as a generic file server. I looked first at drive capacity and expansion, then compared processor and memory resources, network connections, and the practical role of M.2 slots. Those details affect whether a NAS can serve several users, move large files quickly, or take on tasks beyond basic backups.
I also separated home-focused simplicity from heavier workloads. Docker support, virtual machines, photo tools, HDMI output, and operating-system flexibility can matter, but they do not carry equal weight for every buyer. I considered whether memory can be expanded, since an upgrade path may matter more than a larger fixed starting amount. Finally, I accounted for stated drawbacks such as diskless shipping, non-upgradable RAM, required wired networking, and setup demands. The order favors broad capability and room to grow, while the role labels show when a lower-ranked model may be the better match.

Factors to Consider When Choosing Nas 4 Bay Enclosure
A four-bay NAS can be a simple household file hub or a small server for demanding services. I would choose by matching the enclosure’s network, processor, memory, and software support to the work it will actually do.
Decide how much network speed you can use
The DXP4800 Pro’s 10GbE port is the standout link here, but it only helps when the switch, client device, and cabling support a compatible high-speed path. For many homes, dual 2.5GbE on the QNAP TS-464 or TerraMaster F4-424 Pro is a more practical fit. The DH4300 Plus lists one 2.5GbE connection, which is adequate for many household file and media tasks but offers less network flexibility. I would avoid choosing a faster port solely on its headline number if the rest of the network cannot use it.
Treat memory as both a starting point and an upgrade plan
The TerraMaster begins with 32GB DDR5, the largest installed amount in this comparison, but its memory is fixed. The DXP4800 Pro starts at 8GB and can expand to 96GB, making it the more flexible pick for a changing workload. QNAP supports a more modest upgrade to 16GB. The DH4300 Plus lists 8GB LPDDR4X, with no upgrade detail supplied here. If Docker, virtual machines, or several services are part of your plan, compare the upgrade ceiling as carefully as the installed capacity.
Match processing features to the work
A NAS used for backups and shared folders does not need the same resources as one running containers or virtual machines. UGREEN specifies support for both on the DXP4800 Pro, and TerraMaster pairs an eight-core processor with 32GB of memory. QNAP provides a quad-core processor and hardware-assisted encryption. The DH4300 Plus supports Docker but not virtual machines, so it makes more sense for household storage and media than a home-lab host. Software capability matters only if the system can support the services you want to run.
Plan drive capacity, RAID, and backups together
All four products are diskless, so the enclosure is only one part of the storage decision. Buyers still need to choose drives, work out usable capacity, and select a RAID or equivalent layout supported by the NAS. RAID can help maintain availability after certain drive failures, but it is not a replacement for a separate backup. Check the individual model’s drive compatibility and setup guidance before filling all four bays; starting with fewer drives can affect later expansion choices.
Look beyond drive bays for expansion
The M.2 slots distinguish three of these choices from a basic four-drive box: the DXP4800 Pro has two PCIe 4.0 slots, while QNAP lists two PCIe Gen3 x2 NVMe slots and TerraMaster lists two M.2 NVMe slots. Their exact supported uses and setup depend on the system, so confirm whether you want SSD storage or caching before buying. The DH4300 Plus instead emphasizes home media access and HDMI output. For local viewing or a TV-connected setup, that feature may matter more than NVMe expansion.
Account for setup and ongoing use
Tool-free trays on the DXP4800 Pro and F4-424 Pro can simplify drive installation, while the QNAP’s metal enclosure and stated three-year warranty may appeal to buyers prioritizing build details and longer coverage. UGREEN notes that some advanced DXP4800 Pro features require configuration; that is a reasonable trade for users who want more control, but it may not suit someone seeking a minimal setup. The DH4300 Plus is focused on everyday home storage, though it still needs wired Ethernet. Think about where the NAS will sit, who will administer it, and how much time you want to spend configuring services.
Frequently Asked Questions
What does diskless mean for a four-bay NAS?
Diskless means the enclosure is supplied without hard drives or SSDs. You need to purchase compatible drives separately, install them, and configure storage before using the NAS. The four models in this guide are all listed as diskless, so compare the cost and capacity of your planned drives as part of the full system decision.
Which of these four-bay NAS enclosures has the fastest network connection?
The UGREEN DXP4800 Pro lists both 10GbE and 2.5GbE network ports, giving it the fastest stated network option in this group. A 10GbE connection is useful only if your network equipment and client devices can support it. QNAP and TerraMaster list dual 2.5GbE ports, while the DH4300 Plus lists a single 2.5GbE port.
Which model is the best fit for a home lab?
I would start with the UGREEN DXP4800 Pro for its 10GbE connection, expandable memory, Docker support, and virtual-machine support. The TerraMaster F4-424 Pro is another strong candidate when its 32GB of fixed memory suits the planned services. The DH4300 Plus does not support virtual machines, so I would not choose it for a lab built around running them.
Is four-bay RAID a substitute for backing up files?
No. RAID can help keep a storage volume available after certain drive failures, depending on the selected configuration, but it does not protect against every cause of data loss. Accidental deletion, device damage, theft, and other failures can still affect data. I recommend maintaining a separate backup, ideally on another device or in another location, for files that matter.
Should I choose the DH4300 Plus for a home media setup?
The DH4300 Plus is a reasonable match if your priorities are private household storage, photo organization, remote access, and 4K HDMI output. It works over wired Ethernet and does not support Wi-Fi or virtual machines. If your media setup also needs virtualized services or a faster network path, I would compare it with the DXP4800 Pro or QNAP TS-464 instead.
Conclusion
For a home lab or small office that can use 10GbE and needs room for memory growth, I would pick the UGREEN DXP4800 Pro. Buyers who want 32GB installed from day one and can live with fixed memory should look at the TerraMaster F4-424 Pro. For balanced home or small-office storage with dual 2.5GbE, NVMe options, and a longer stated warranty, the QNAP TS-464 is the sensible fit. If the job is household photo backup and media access rather than virtual machines, I would choose the UGREEN DH4300 Plus. Whichever enclosure fits, remember to plan for separate drives, a suitable RAID layout, and an independent backup.
