How to choose a 12-bay NAS in 2026
Twelve bays is proper rack country: Synology's DS2422+ is the rare 12-bay desktop tower, QNAP's TS-1264/1232PXU lines cover the rack, and TerraMaster's T12 series rounds it out. Drive choice at this scale is an enterprise-drive conversation — every model page links the vendor's tested list.
Current-generation picks
The models you can actually buy new today — one card each, with the official drive-list depth most spec sheets never show:
