Best M.2 NVMe for the UGREEN NASync DH4300 Plus
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DH4300 Plus has no M.2 slots, so an NVMe cache is not possible on this model — no m.2 slots Over its 1 × 2.5GbE, that is barely a loss: a single CMR drive already saturates the link, and a cache only helps data you read repeatedly. If cache or a fast NVMe pool matters to you, choose a model with M.2 slots.

Do you actually need NVMe on the DH4300 Plus?
An NVMe cache accelerates random I/O — the many small, scattered reads and writes you get when lots of users, a database or virtual machines all hit the array at once. It does almost nothing for the workload the DH4300 Plus is built for: sequential file transfers, device backups and everyday storage. On this model the 1 × 2.5GbE connection is the real ceiling, so a cache sitting in front of the drives would have no headroom to give — the network fills up long before the disks become the bottleneck.
Put the money where it moves the needle instead. The bigger win is capacity: larger CMR drives with the best CA$/TB, sized in the drive-count calculator. If you genuinely need a cache — a busy multi-user array, 10-gigabit networking, or a database/VM workload — that is simply a different class of NAS: an Intel model with M.2 slots and faster networking. Our SSD cache guide explains when a cache earns its place and when it does nothing, and drives by model lists the boxes that have the slots.
What sets the DH4300 Plus apart
The affordable ARM version with four bays. The memory is soldered, so you decide once and for good at purchase: 8 GB stays 8 GB. That is exactly why the DH line is a file store, not a container platform.

Frequently asked questions
How many M.2 slots does the DH4300 Plus have?
None. No M.2 slots
Is an NVMe cache worth it in the DH4300 Plus?
Not possible — the DH4300 Plus has no M.2 slots. Over its 1 × 2.5GbE a cache would add little anyway, since a single drive already saturates the link.
Can I put third-party drives in the DH4300 Plus?
Yes. UGREEN locks no drive brand on the DH4300 Plus — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
