Best M.2 NVMe for the UGREEN NASync DXP4800
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DXP4800 has 2 M.2 slots. They are freely populated (2 × m.2 nvme, usable as cache or as their own storage pool), so a Samsung 990 EVO, WD Red SN700 or Crucial P3 all work. Whether a cache pays off depends on the 2 × 2.5GbE (link-aggregable to 5 Gbit/s) link and on whether you re-read the same data — for a media library streamed once, it does not.

What sets the DXP4800 apart
The frugal version of the DXP4800 Plus: the same four-bay build, but the N100 instead of the Pentium and two 2.5-gigabit ports instead of 10GbE. For file storage and backup that is plenty; the 16 GB RAM ceiling is the real limit.
Cache or a fast pool on the DXP4800?
The DXP4800's 2 M.2 slots (2 × m.2 nvme, usable as cache or as their own storage pool) can serve as a read cache or, depending on the OS, as their own fast storage pool. A cache only speeds up data you read more than once: on the DXP4800, a media library streamed through once gains nothing, while repeated project files, photo libraries or container images show the difference immediately. Weigh that against its 2 × 2.5GbE (link-aggregable to 5 Gbit/s) link, which is often the real limit.
Because the DXP4800 takes any M.2 drive, a Samsung 990 EVO, WD Red SN700 or Crucial P3 all work; for a write cache or VM pool, pick one with a real TBW rating rather than a DRAM-less budget SSD, since a cache wears faster than normal use.

Keep calculating
To see how much capacity is left after parity, the DXP4800 capacity calculator is preset to its 4 bays and RAID types. For the DXP4800, the wider basics of choosing a drive are in the buying guides, where we also explain why CMR rather than SMR is mandatory in any RAID array.
Frequently asked questions
How many M.2 slots does the DXP4800 have?
2. 2 × M.2 NVMe, usable as cache or as their own storage pool
Is an NVMe cache worth it in the DXP4800?
Only if you re-read the same data on the DXP4800: project files, photos, container images. A media library streamed once gains nothing, and with 2 × 2.5GbE (link-aggregable to 5 Gbit/s) the link is often the limit before the drive is.
Can I put third-party drives in the DXP4800?
Yes. UGREEN locks no drive brand on the DXP4800 — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
