UGREEN NASync DH4300 Plus: compatible drives
By Devin Chua · Data checked by Owen Nakamura · Updated For the UGREEN NASync DH4300 Plus fit CMR NAS drives like WD Red Pro or Seagate IronWolf Pro across all 4 bays up to 128 TB raw. UGREEN locks no drive brand on the DH4300 Plus; its compatibility list is guidance, not a gate. At 4 × 8 TB the DH4300 Plus keeps 21.83 TiB usable in RAID 5, about CA$2,288 in drives. Since its ARM 8-core (Cortex-A76 and A55, 2.4 GHz) serves files and backups quietly but does not hardware-transcode Plex or run real virtual machines, an ordinary CMR drive already saturates the DH4300 Plus's link.

What fits the DH4300 Plus
| Drive type | Status | Detail |
|---|---|---|
| 3.5-inch SATA hard drive (CMR) | Fits | UGREEN publishes no per-drive size limit; its compatibility list shows tested sizes. |
| 2.5-inch SATA SSD | not stated by UGREEN | UGREEN does not say the bays take 2.5-inch drives. |
| SAS drive | Does not fit | The bays are SATA; a SAS drive needs a SAS controller. |
| SMR hard drive | Avoid in RAID | Works alone, but can stall a rebuild for days. Check the model number against the maker's CMR/SMR list. |
| M.2 SATA SSD (for example WD Red SA500 …R0B) | Does not fit | Not a bay drive, and there is no M.2 slot. |
| M.2 NVMe SSD | No slot | The DH4300 Plus has no internal M.2 slot. |
How we decide what is compatible
A part reaches our shortlist for the DH4300 Plus only when it meets UGREEN’s published specifications for its form factor, interface, size and memory type, and, where UGREEN requires its own compatibility list (as Synology does for M.2 NVMe), when it is on that list. Parts that fit physically but are not on a required list are shown separately and labelled. Parts that depend on a detail UGREEN does not publish are labelled “fit not confirmed”. Anything that does not fit is left out. Our methodology explains each step.

Keep calculating
To see how much capacity is left after parity, the DH4300 Plus capacity calculator is preset to its 4 bays and RAID types. For the DH4300 Plus, the wider basics of choosing a drive are in the buying guides, and CMR versus SMR explains why SMR drives do not belong in a RAID array.

Frequently asked questions
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.
Which drives fit the DH4300 Plus?
The DH4300 Plus takes any 3.5-inch SATA drive; use a CMR NAS family rated for 24/7 duty such as IronWolf, WD Red Plus or Toshiba N300. On its 1 × 2.5GbE, a standard CMR drive is already fast enough for the DH4300 Plus.
How much capacity is usable in the DH4300 Plus?
In the DH4300 Plus, 4 × 8 TB in RAID 5 gives about 21.83 TiB usable and survives 1 drive failing; the balance is parity.
Can the DH4300 Plus run Plex with hardware transcoding?
Only in software. The DH4300 Plus's ARM 8-core (Cortex-A76 and A55, 2.4 GHz) has no Quick Sync, so Plex transcodes on the CPU: enough for direct play, not for heavy 4K transcoding.
Is a Pro drive worth it in the DH4300 Plus?
Marginal. The DH4300 Plus's 1 × 2.5GbE sits right where a standard CMR drive already saturates the link, so a Pro drive mainly buys warranty, not speed.
