How much storage fits in the UGREEN NASync DXP4800 Plus?
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DXP4800 Plus takes 4 drives, up to 144 TB raw, but usable is the number that matters: 4 × 8 TB in RAID 5 gives 21.83 TiB, and it survives 1 drive failing. The gap from raw capacity is parity.

CMR NAS drives for the DXP4800 Plus, by price per TB
Only families with confirmed CMR recording and a 24/7 rating, in stock on Amazon.ca and sized for the DXP4800 Plus. SMR drives are deliberately kept out.
What sets the DXP4800 Plus apart
The model putting Synology under pressure: 10-gigabit networking out of the box, up to 64 GB of RAM, four bays. To actually saturate the 10GbE link you need four quick CMR drives here or the NVMe cache, otherwise the drive is the limit, not the network.
Who the DXP4800 Plus is for
The DXP4800 Plus steps a clear rung above the N100 class. The Intel Pentium Gold 8505 (5 cores, 6 threads) has the threads for several concurrent Plex transcodes plus a couple of genuine virtual machines beside your containers, and with up to 64 GB of memory it has the headroom to run them. Paired with its 1 × 10GbE and 1 × 2.5GbE, the DXP4800 Plus is the UGREEN aimed straight at Synology's Plus range.
How the DXP4800 Plus's network shapes the drive choice
The DXP4800 Plus ships with 1 × 10GbE and 1 × 2.5GbE, and that rewrites the maths. Ten gigabit is about 1,100 MB/s; a single drive gives 150 to 280 MB/s and a 4-drive array three to four times that, so you close much of the gap without ever quite saturating the link. On the DXP4800 Plus, for the first time, a 7200 rpm Pro drive earns its price — and the NVMe cache earns its slot by keeping hot data off the spinning disks.
A worked configuration for the DXP4800 Plus
Seagate IronWolf Pro or WD Red Plus in every bay is the recommendation for the DXP4800 Plus. At 4 × 8 TB in RAID 5, the DXP4800 Plus lands 21.83 TiB usable, gives up 8 TB to parity, and survives 1 drive failing. Step the same 4 bays of the DXP4800 Plus up to 16 TB drives and it holds roughly twice that, at the CA$/TB the live table above shows.
RAID 5 or RAID 6 in the DXP4800 Plus?
With 4 bays the DXP4800 Plus gives a real choice. In RAID 5 it keeps 21.83 TiB of the 4 × 8 TB and survives one failure; RAID 6 spends one more drive for two. The trade tips with large drives: after a failure the DXP4800 Plus must read every surviving drive in full to rebuild, which on 20 TB drives runs the better part of a day under peak load. So from 16 TB per drive up, RAID 6 is the calmer choice in the DXP4800 Plus.
One rule holds on every NAS, the DXP4800 Plus included: use CMR drives, not SMR. SMR drives rewrite overlapping tracks and collapse during a RAID rebuild, dragging a repair from hours into days.

Frequently asked questions
What is the maximum storage in the DXP4800 Plus?
4 drives, up to 144 TB raw per the manufacturer. 4 × 32 TB hard drives plus 2 × 8 TB NVMe, per the manufacturer
How much of the DXP4800 Plus is actually usable?
In the DXP4800 Plus, 4 × 8 TB in RAID 5 yields about 21.83 TiB — that is 24 TB in drive-maker terms, with 8 TB to parity. It shows less than the label because it counts in powers of two.
Can I fit larger drives in the DXP4800 Plus later?
Yes, but on the DXP4800 Plus classic RAID sizes to the smallest drive, so the extra space arrives only once every drive is replaced. There is no flexible RAID like SHR on this model.
Can I put third-party drives in the DXP4800 Plus?
Yes. UGREEN locks no drive brand on the DXP4800 Plus — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
