We wouldn’t normally test two products from the same lineup in two consecutive issues of the magazine. But when Western Digital’s My Book 3.0 showed up just days after the March issue went to print (it's on newsstands now!), we knew we had to review it. It doesn’t have an e-label or capacity meter, like the My Book Elite. Nor does it include WD’s SmartWare backup software or hardware encryption. But the My Book 3.0 has one feature that makes it awesome: USB 3.0.
