Before you buy

  • Check USB4 support on the host and its OS. RAID requires host software; the enclosure does not provide it.
  • 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.
