For a NAS with SSD cache, the main choice is whether you need high-speed networking, more drive bays, or a smaller system with dual NVMe slots. I put the UGREEN DXP4800 Pro first for its Core i3 processor, expandable memory, and fast 10GbE connection; the DXP4800 Plus is the more straightforward four-bay pick with a listed 128GB SSD; and the DXP2800 suits buyers who want a compact two-bay setup with two NVMe slots. The tradeoff is practical: extra cache and network bandwidth help most when your apps or files can use them, while drive capacity, RAID choices, and setup needs still shape everyday value.

One distinction matters before choosing: an M.2 slot or included SSD does not, by itself, confirm how the NAS handles cache, which workloads benefit, or whether cache is configured automatically. I weigh the stated SSD and NVMe provisions alongside bays, CPU, RAM, and Ethernet, and flag where the supplied details do not specify cache behavior. All three are presented as diskless for the main storage drives, so plan for separate drive selection.

Key Takeaways
- The DXP4800 Pro is the strongest fit for demanding workloads that can benefit from 10GbE, dual M.2 PCIe 4.0 slots, and memory expansion.
- The DXP4800 Plus also pairs 10GbE with four bays and lists a 128GB SSD, but its description does not explain that SSD’s cache role.
- The DXP2800 offers two NVMe slots in a smaller two-bay design, making it the compact option rather than the best choice for maximum capacity.
- Each model has a different balance of bays and SSD provisions: two M.2 slots on the Pro, a listed 128GB SSD on the Plus, and dual NVMe slots on the DXP2800.
- Do not expect cache to compensate for slow networking or unsuitable drives: the 2.5GbE DXP2800 has a lower network ceiling than the four-bay models’ 10GbE ports.

More Details on Our Top Picks
UGREEN NAS DXP4800 Pro 4-Bay Network Attached Storage
I rank the DXP4800 Pro first because it combines the most complete performance foundation here: a Core i3-1315U, two PCIe 4.0 M.2 slots, and both 10GbE and 2.5GbE networking. That combination gives buyers room to build a fast storage pool and serve multiple demanding uses, from file sharing to Docker and virtual machines. Its 8GB of DDR5 can expand to 96GB, so the system has a clearer upgrade path than a fixed-memory appliance.
Compared with the DXP4800 Plus, the Pro’s advantage is spelled out most clearly in its processor and M.2 interface details. Both four-bay systems support up to 144TB as specified and include 10GbE networking, but the Plus lists a 128GB SSD while the Pro’s supplied details emphasize two SSD slots instead. I would not treat either point as proof of a particular cache setup: the provided information does not explain cache policy or configuration. Buyers should confirm how UGOS Pro handles SSD cache for their intended workload.
This is the better fit when several users, large files, or self-hosted services justify the stronger hardware. The downside is that its capabilities can be wasted on simple backups, and the advertised read rate depends on the network, drives, and configuration. The four-bay chassis also requires separate drives, and RAID choices trade usable capacity for redundancy. Against the smaller DXP2800, it costs more space and setup effort in exchange for more bays and much faster networking.
Pros:- Two PCIe 4.0 M.2 slots provide SSD expansion options.
- 10GbE plus 2.5GbE is a stronger networking mix than the DXP2800 offers.
- Core i3-1315U and expandable DDR5 memory suit apps and virtual machines.
- Four bays support larger storage pools and RAID 0, 1, 5, or 10.
Cons:- Main storage drives are not included.
- The supplied details do not explain cache configuration or how workloads benefit.
- Its higher capability can be unnecessary for straightforward file backup.
Best for: Home labs, creators, and small teams that want a four-bay NAS with dual M.2 slots, 10GbE, and room to expand memory.
Not ideal for: Buyers who only need basic backups, prefer a compact two-bay system, or want a confirmed out-of-box cache configuration without further setup checks.
- Processor:Intel Core i3-1315U, 6 cores, 8 threads
- Memory:8GB DDR5, expandable to 96GB
- Drive bays:4
- Maximum capacity:Up to 144TB, dependent on installed drives
- Networking:10GbE and 2.5GbE
- SSD provisions:2 PCIe 4.0 M.2 slots
- RAID:0, 1, 5, and 10
- Operating system:UGOS Pro
Our verdict“I recommend the DXP4800 Pro for buyers who can use its 10GbE, dual M.2 slots, and upgrade headroom, while noting that cache behavior needs confirmation.”
UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams
The DXP4800 Plus is the more direct choice for someone who wants a four-bay NAS and sees value in an SSD already listed in the configuration. Its specs include a 128GB SSD, 8GB of DDR5, and a five-core Intel CPU, alongside 10GbE and 2.5GbE ports. That makes it appealing for families and small teams building a media library or shared workspace without moving to a more elaborate model description.
For SSD-cache buyers, though, the product details leave an important gap: they name a 128GB SSD but do not state whether it is assigned as cache, system storage, or another purpose. I would verify that point before buying if cache is the deciding feature. The DXP4800 Pro is clearer about its two PCIe 4.0 M.2 slots and offers a more explicit memory ceiling; the Plus counters with its listed SSD and broadly similar four-bay, dual-Ethernet setup. Neither model’s headline transfer figure guarantees the same result on a typical home network.
The Plus makes sense when you want four HDD bays, 10GbE potential, and support for Docker, virtual machines, and photo organization, but do not need the Pro’s specified memory expansion ceiling. It is also more substantial than the two-bay DXP2800, which gives up capacity and 10GbE for a smaller footprint. The tradeoffs are familiar but meaningful: the main hard drives are separate purchases, Wi-Fi is not built in, and SSD cache behavior is not described. I would choose it for its overall four-bay balance, not assume its listed SSD automatically delivers a particular cache benefit.
Pros:- Four bays and up to 144TB capacity support a sizable storage pool.
- A 128GB SSD is listed alongside 10GbE and 2.5GbE networking.
- 8GB DDR5 and an Intel five-core CPU support multitasking and NAS apps.
- Encryption and permission management support shared household or team use.
Cons:- The 128GB SSD’s role is not specified in the supplied product details.
- Hard drives must be purchased separately.
- Actual throughput depends on the network, drives, and workload.
Best for: Families, creators, and small teams who want four HDD bays, 10GbE networking, and an SSD listed in the configuration.
Not ideal for: Buyers who require clear documentation that the listed SSD is cache, or those who need the most explicit M.2 and memory-upgrade details.
- Processor:Intel five-core CPU
- Memory:8GB DDR5
- Drive bays:4
- Maximum capacity:Up to 144TB, with drives sold separately
- Networking:1× 10GbE and 1× 2.5GbE
- SSD listed:128GB SSD; stated use is not specified
- Advertised read speed:Up to 1,250MB/s; actual results depend on configuration
- Warranty:2 years
Our verdict“I would choose the DXP4800 Plus for a capable four-bay setup with an SSD listed, after confirming whether that SSD serves as cache for your use.”
UGREEN NAS DXP2800 2-Bay
The DXP2800 earns its place as the compact option: it pairs a two-bay design with an Intel N100, 8GB of DDR5, and dual NVMe slots. That gives a home user or remote worker a route to add SSDs while keeping the main storage pool relatively simple. It also supports Docker, virtual machines, Plex, photo management, and surveillance features, so it is more capable than a basic file-sharing box.
Compared with the four-bay DXP4800 models, the DXP2800 gives up two HDD bays and the 10GbE port. Its 2.5GbE connection is more appropriate for a compact home network than for a workflow built around very large transfers or multiple high-bandwidth users. The supplied read and transfer figures are lower than those listed for the four-bay options, and I would avoid comparing advertised rates as if they were guaranteed real-world results. Drive type, configuration, and network equipment all affect performance.
For SSD cache specifically, its dual NVMe slots are attractive, but the product information does not spell out the supported cache mode or setup steps. I would confirm software support before buying with a cache-only goal. The DXP2800 is a better match for a buyer prioritizing footprint and a manageable two-bay storage system than for someone building a large shared archive. It may also ask more of a beginner who wants to configure containers or surveillance, and the drives are not included.
Pros:- Dual NVMe slots give it a clear SSD expansion path in a compact two-bay design.
- Intel N100 and 8GB DDR5 support Docker, virtual machines, and Plex workloads.
- 2.5GbE fits faster-than-gigabit home networking.
- Photo management and surveillance features extend beyond file storage.
Cons:- Two HDD bays limit capacity and RAID flexibility compared with the four-bay models.
- It lacks the 10GbE networking offered by both DXP4800 options.
- The cache setup and supported behavior are not detailed, and drives are sold separately.
Best for: Advanced home users and remote workers who want a two-bay NAS with dual NVMe slots, 2.5GbE, and support for self-hosted apps.
Not ideal for: Small teams needing 10GbE, buyers planning a large multi-drive storage pool, or beginners who do not want to configure advanced apps.
- Processor:Intel N100 quad-core
- Memory:8GB DDR5
- Drive bays:2
- Maximum capacity:Up to 80TB, dependent on installed drives
- Networking:2.5GbE Ethernet
- SSD provisions:2 NVMe slots
- Storage interface:SATA
- Warranty:2 years
Our verdict“I recommend the DXP2800 when compact size and dual NVMe matter more than four bays or 10GbE throughput.”
How We Picked
I ranked these three NAS systems around the promise in the search: SSD cache and practical NAS fit, not raw specifications alone. I compared the stated M.2 or NVMe provisions, included SSD information, drive bays, supported capacity, networking, memory, and processor class. I gave extra weight to options that pair room for SSDs with a clear reason a buyer might benefit, such as multi-user transfers, apps, or a larger storage pool.
I also kept the limits of the supplied details visible. An SSD slot does not prove that a unit includes cache software, that caching is enabled by default, or that every workload gets faster. The DXP4800 Plus description lists a 128GB SSD but does not say what it is used for; the Pro and DXP2800 list SSD slots without a supplied cache policy. I treat these as SSD-ready options, rather than promising a particular cache result.
Ranking reflects those differences. The DXP4800 Pro leads because its two PCIe 4.0 M.2 slots sit alongside dual 10GbE and 2.5GbE networking, a capable CPU, and expandable DDR5 memory. The Plus follows as a strong four-bay alternative with an included SSD listed, but less clarity about its role. The two-bay DXP2800 comes third for this specific roundup: its dual NVMe slots are appealing, yet 2.5GbE and fewer HDD bays make it a better compact choice than a high-throughput, high-capacity centerpiece. I do not assume the advertised maximum speeds will match every network or drive configuration.
| nas with ssd cache | Processor | Maximum capacity |
|---|---|---|
| UGREEN NAS DXP4800 Pro 4-Bay N | Intel Core i3-1315U, 6 cores, 8 threads | Up to 144TB, dependent on installed drives |
| UGREEN DXP4800 Plus 4-Bay NAS | Intel five-core CPU | Up to 144TB, with drives sold separately |
| UGREEN NAS DXP2800 2-Bay | Intel N100 quad-core | Up to 80TB, dependent on installed drives |
Factors to Consider When Choosing Nas With Ssd Cache
I would choose a NAS with SSD cache by matching the SSD arrangement to the work it will do. Slot count is only part of the decision: the drive pool, network, apps, and cache software determine whether added SSDs make a noticeable difference.
Separate SSD slots from confirmed cache support
M.2 or NVMe slots mean expansion options, not necessarily a defined cache configuration. Ask whether the SSD can serve as read cache, write cache, system storage, or a separate volume; the difference affects both performance and risk. These product details do not establish cache modes for any of the three models. The Plus lists a 128GB SSD, but its purpose is not stated. I would verify the NAS software’s current instructions before treating any included or optional SSD as cache.
Match network speed to your transfers
The DXP4800 Pro and Plus list 10GbE alongside 2.5GbE; the DXP2800 lists 2.5GbE. A fast SSD cache cannot overcome a slower link when transferring large files to one computer. To benefit from 10GbE, the client, switch or direct connection, and cabling must support it too. For many households with a 2.5GbE network, the DXP2800 may be a more proportionate fit, while creators moving large projects may prefer the four-bay models’ faster network option.
Choose bays and RAID for capacity needs
Four bays offer more room to build a storage pool than two, but extra bays do not automatically provide protection. RAID 5 or RAID 10 can help tolerate certain drive failures, but RAID is not a backup. The DXP4800 models list up to 144TB, while the DXP2800 lists up to 80TB; actual supported capacity depends on installed drives and configuration. Plan for a separate backup of irreplaceable files, and confirm compatibility before buying drives.
Think about workload and setup
Frequent access to a working dataset, photo library, or app data may make SSD features more relevant than occasional sequential backups. For large sequential media files, network and HDD performance may matter more. The Pro’s Core i3 and expandable memory suit a heavier mix of services; the Plus gives families and small teams a four-bay platform; the DXP2800 can run containers and virtual machines in a smaller design. Advanced apps can require hands-on setup, so a beginner may prefer a simpler file-storage configuration.
Budget for the complete storage setup
All three listings indicate that main storage drives are sold separately, so compare the total setup rather than the enclosure alone. Include suitable HDDs, any NVMe SSDs you intend to add, and backup storage. The Plus is the only one here that lists a 128GB SSD, but buyers should confirm its purpose; the Pro and DXP2800 specify SSD slots without an included cache drive in the supplied descriptions. Capacity, redundancy, and backup each need their own plan.
Frequently Asked Questions
What does SSD cache do in a NAS?
SSD cache uses solid-state storage to hold data that may be accessed again, potentially speeding some repeated or random operations. The benefit depends on workload, cache mode, NAS software, and network speed. It is not a universal upgrade for every file transfer, and it does not replace a backup. Confirm the NAS supports the cache behavior you need before adding an SSD.
Which of these models is the strongest fit for SSD cache?
I rank the DXP4800 Pro first because it specifies two PCIe 4.0 M.2 slots and pairs them with 10GbE, a Core i3 processor, and expandable memory. That makes it the most capable foundation for demanding use in this group. Its supplied description still does not detail the cache modes, so buyers should check UGOS Pro documentation for the intended configuration.
Does the DXP4800 Plus include an SSD cache drive?
The supplied DXP4800 Plus specifications list a 128GB SSD, but they do not explain whether it serves as cache, system storage, or another purpose. I would not assume it is configured as cache based only on that listing. Confirm the SSD’s role and whether the desired cache feature is supported before choosing the Plus for that reason.
Is the DXP2800 a good choice for a small home NAS?
It can be a good fit if you want two HDD bays, dual NVMe slots, 2.5GbE, and support for home apps such as Plex or Docker. It is less suited to buyers who need the four-bay capacity or 10GbE ports of the DXP4800 models. The product details also do not explain its cache setup, so confirm software support if SSD caching is a main requirement.
Will SSD cache make every NAS transfer faster?
No. Cache is most likely to help workloads involving repeated or random access, while a large one-time sequential transfer may be limited by the drives, client, or network. A 10GbE NAS also needs a compatible client and network path to use that link’s potential. I would match the cache and network investment to the actual files and applications rather than expecting a universal speed increase.
Conclusion
For the strongest all-around performance foundation, I would choose the DXP4800 Pro: it has four bays, dual PCIe 4.0 M.2 slots, 10GbE, and room to expand memory. Choose the DXP4800 Plus if you want a four-bay family or small-team NAS and value that a 128GB SSD is listed, but first verify its purpose. Pick the DXP2800 for a more compact two-bay system with dual NVMe slots when 2.5GbE is enough and you do not need four drive bays. For all three, check cache support and configuration, budget for the main drives, and maintain a separate backup.
