Failure rate No failure data Sizes 0.5 TB 1 TB 2 TB 3 TB 4 TB 6 TB 8 TB 10 TB 12 TB Good for A PC, or a backup copy you plug in now and then Not for A NAS (WD gives it no NAS rating) Updated 27 Oct 2026 · Method 2.0
Should you buy the WD Blue 8 TB? A PC tower suits it, or a dock for backups.
! Watch out forWD doesn't rate it for NAS use at all, which rules it out for an array as far as we're concerned.
Backblaze doesn't run enough of these for a failure rate we'd publish. WD's datasheet puts it at 24 dB idle and 28 dB seeking. Power draw is 3.4 W idle and 5.2 W working on WD's figures, or 30 kWh a year if it spends the whole year idling.
