WD My Book Spec and Price in the United States

USB8TB

My Book is WD's desktop backup line: a 3.5-inch drive with hardware AES-256 encryption and WD Backup software, USB 3.0, and a three-year warranty, per the WD product overview. Over the Elements Desktop it adds the encryption and software bundle for a small premium. It has long been the default recommendation for large local backups — the 18-22TB SKUs are the largest single-drive desktop externals WD sells.

What owners and reviewers say

Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • A more compact enclosure than the outgoing model, with straightforward on-site and cloud backup software.
  • Includes password protection and hardware encryption, with performance well matched to backup duties.

Commonly criticised

  • No internal component upgrades over the previous generation, so it is largely a cosmetic refresh.
  • The glossy finish smudges easily, and it carries only a two-year limited warranty.
