Best 8-bay NAS — every model, every vendor, one table

How to choose a 8-bay NAS in 2026

Eight bays is small-business territory: RAID 6 across eight spindles, 100+ TB raw with modern drives, and redundant everything. Synology's DS1821+/DS1823xs+ anchor the top end with the best software stack, QNAP's TS-873A/TS-864 and the U.2-capable TS-832PXU cover the middle, and UGREEN's DXP8800 Plus/Ultra bring 10GbE and DDR5 at prices that undercut both incumbents by hundreds. UniFi's UNAS Pro 8 ($799, dual 550W PSUs, 16 GB RAM) is the newest entrant — with a spec-based drive policy instead of a whitelist.

At eight drives, array rebuilds take a day or more — this is the bay count where sticking to each vendor's officially listed drives pays off most. The cross-checked drive table below shows which part numbers the most {n}-bay machines list.
