Best M.2 NVMe for the UGREEN NASync DH2300
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DH2300 has no M.2 slots, so an NVMe cache is not possible on this model — no m.2 slots Over its 1 × 1GbE, 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 DH2300?
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 DH2300 is built for: sequential file transfers, device backups and everyday storage. On this model the 1 × 1GbE 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 DH2300 apart
The cheapest NASync model and deliberately lean: 1-gigabit networking, 4 GB of soldered RAM, no Docker. Watch out for reviews that quote RK3588C, 8 GB and 2.5GbE: those are the DH4300 Plus specs, not the DH2300.
The UGREEN drive policy on the DH2300
unrestrictedOpen. UGREEN mandates no drive brand. The compatibility list is a recommendation, not a lock.

Keep calculating
To see how much capacity is left after parity, the DH2300 capacity calculator is preset to its 2 bays and RAID types. For the DH2300, 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 DH2300 have?
None. No M.2 slots
Is an NVMe cache worth it in the DH2300?
Not possible — the DH2300 has no M.2 slots. Over its 1 × 1GbE a cache would add little anyway, since a single drive already saturates the link.
Can I put third-party drives in the DH2300?
Yes. UGREEN locks no drive brand on the DH2300 — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
