The short version

The WD Blue 4TB is Western Digital's mainstream desktop hard drive, using CMR recording at 5400 RPM with a 256MB cache and transfers up to 185 MB/s. It suits general file storage and game archives in a desktop PC, and CMR avoids the rewrite penalty of SMR drives such as the 4TB BarraCuda. The warranty is only two years, and its 5400 RPM spindle is slower than performance-focused desktop drives.

Pros

  • CMR recording avoids SMR rewrite penalties
  • 256MB cache
  • Up to 185 MB/s transfer rate

Cons

  • Two-year warranty is short
  • 5400 RPM is slower than performance drives
  • No independent review of this exact model was read

Best for

  • Desktop file and game archives
  • Secondary storage on a budget

Common questions

Is the WD Blue 4TB CMR?

Yes. Western Digital's specification table for model WD40EZAX lists CMR recording, a 5400 RPM speed and a 256MB cache.

Is it good for a NAS?

It is designed for desktop PCs and carries a two-year warranty, so a NAS-rated drive such as the WD Red Plus is the better fit for always-on use.
