Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • HAT3300-8T is a different, slower family; the Plus Series page lists HAT3320-8T with 7200 rpm.
  • HAT3310-12T and HAT3310-16T are higher-capacity 5400-class family members, not this model.
  • Enterprise class HAT5300/5320 drives are a different Synology line, not Plus Series.

Why people pick it

  • CMR recording, suited to NAS RAID arrays rather than SMR drives
  • 7200 rpm with up to 281 MB/s sustained transfer rate
  • Firmware updates ship through DSM, the same interface as the NAS itself
  • Validated on Synology's own compatibility list for its RackStation and DiskStation models

Know before you buy

  • No maker-linked retail listing: Synology sells through resellers, so the exact ASIN must be found on Amazon
  • Plus Series drives are tuned for 1-16 bay NAS; larger arrays are better served by Enterprise class
  • Only Synology compatibility-validated; the maker does not publish third-party NAS validation
