NAS Units

Synology NAS units — DiskStation desktop enclosures from two to twelve bays and RackStation rackmount arrays. Drives are sold separately unless the product name says otherwise; see NAS drives.
Choosing a NAS covers bay count, RAID and what genuinely needs 10 GbE. Check Synology’s compatibility list for your intended drives — an unlisted drive usually works but costs you support cover if it plays up.
