It’s been a long time since we reviewed a USB external drive—not since November 2008, to be exact—mostly because they’re essentially commodities now. With transfers capped at USB 2.0 speeds and drive sizes mostly standardized, portable hard drives have had few features by which to distinguish themselves from their peers—the usefulness of included software, eSATA support, and full-disk encryption among them. On the eve of USB 3.0 drives, the Western Digital My Book Elite 2TB seems to be the state of the USB 2.0 drive art, with a custom e-ink display. But is it more than a gimmick?The My Book Elite shares the vaguely book-like formfactor of the My Book World and Essential lineups, but along its “spine” is the e-ink display, which shows a custom 12-character drive label, a capacity meter, and a little lock icon if you’ve enabled disk encryption. Despite its limited usefulness, we dig it—mostly because we geek out over any applications with e-ink.
