The UGREEN DH4300 Plus is £279.99 today, at or below the lowest price we have recorded for it (£313.99 on 23 Jul 2026). The best-value drive to fill it at a genuine low is the WD Red Pro 22TB at £365.00 (£16.59/TB).
The DH4300 Plus takes the DH2300's low-power ARM platform to four bays, with 8GB of soldered memory and 2.5GbE. It is the cheapest route to RAID 5 in UGREEN's range and suits bulk media and household backups rather than heavy apps. We check its price against our log and then fill all four bays with today's cheapest matching drives.

Frequently asked questions
DH4300 Plus or DXP4800 Plus?
The DH4300 Plus costs much less and sips power, but its ARM chip limits transcoding and apps. The DXP4800 Plus adds an Intel CPU, M.2 slots and 10GbE for media and faster transfers.
How much usable space do four drives give in RAID 5?
Roughly three drives' worth after formatting, so four 8TB drives give about 22TB usable. The fill table works this out for each drive size.
Does the DH4300 Plus have M.2 slots?
No. Storage is the four 3.5-inch bays only, which keeps it simple and cheap.
Is 8GB of soldered RAM a limit?
For file sharing, photos and backups, no. It rules out larger Docker stacks and virtual machines.
