How much storage fits in the UGREEN NASync DXP4800?
By Devin Chua · Data checked by Owen Nakamura · Updated The UGREEN NASync DXP4800 takes 4 drives, up to 136 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, 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. SMR drives are deliberately kept out.
What sets the DXP4800 apart
The frugal version of the DXP4800 Plus: the same four-bay build, but the N100 instead of the Pentium and two 2.5-gigabit ports instead of 10GbE. For file storage and backup that is plenty; the 16 GB RAM ceiling is the real limit.
Who the DXP4800 is for
The DXP4800's Intel N100 (4 cores) is the home-NAS sweet spot. Its integrated graphics hardware-transcode Plex — 4K HEVC included, through Intel Quick Sync — and it runs a stack of Docker containers without complaint; heavy virtualization is the one thing it leaves to bigger machines. With 8 GB stock and up to 16 GB, the DXP4800 suits a household that wants its media server and its drives in one quiet box.
How the DXP4800's network shapes the drive choice
The DXP4800 runs 2 × 2.5GbE (link-aggregable to 5 Gbit/s). Two-and-a-half gigabit is about 280 MB/s — almost exactly what a modern high-capacity NAS drive reads off its outer tracks — so the DXP4800 sits in the sweet spot where an ordinary CMR drive saturates the link and a Pro model buys nothing on speed. Drives under about 8 TB fall short here for lack of areal density; from 8 TB up, a standard IronWolf or WD Red Plus is the right call on the DXP4800.
A worked configuration for the DXP4800
Seagate IronWolf Pro or WD Red Plus in every bay is the recommendation for the DXP4800. At 4 × 8 TB in RAID 5, the DXP4800 lands 21.83 TiB usable, gives up 8 TB to parity, and survives 1 drive failing. Step the same 4 bays of the DXP4800 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?
With 4 bays the DXP4800 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 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.
One rule holds on every NAS, the DXP4800 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?
4 drives, up to 136 TB raw per the manufacturer. Manufacturer figure based on 30 TB drives; correspondingly more with 32 TB drives
How much of the DXP4800 is actually usable?
In the DXP4800, 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 later?
Yes, but on the DXP4800 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?
Yes. UGREEN locks no drive brand on the DXP4800 — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
