How to choose 6 TB hard drives

What to look for

  • Price per TB: compare with 4 TB ($50 median) and 8 TB ($41 median) per TB.
  • Recording method: choose CMR for NAS and RAID use.
  • Line: NAS (IronWolf, WD Red), surveillance (SkyHawk, WD Purple) and desktop drives are tuned for different workloads.
  • Warranty: check the term, especially on renewed drives.

Best for

A mid-size NAS drive, a surveillance recorder or a desktop with plenty of media.

Skip it if

A larger or smaller size gives a clearly lower price per TB for your needs.
