Before you buy

  • Check Synology’s current compatibility list for the exact drive, NAS model and DSM version.
  • NVMe slot presence does not guarantee arbitrary SSDs can form a storage pool.
  • Drives are separate purchases. Confirm the exact model and hardware revision in the manufacturer compatibility list.
  • Keep an independent backup of irreplaceable files. RAID does not protect against every cause of data loss.
