My Book Essential Edition meets the needs of users who seek simple, instant storage. Demonstrations of the newly redesigned My Book family of external hard drives may be viewed at WD’s booth (No. 864) ...

Some external hard drives actually come with the add-in card themselves: the Western Digital My Book 3.0 (for desktops) and the Seagate BlackArmor PS 110 USB 3.0 (for laptops).

WD’s My Book external USB hard drive now comes in a 22TB model for $600. There’s also a Duo model that has 44TB capacity for $1,100.

WD®, the world's leader in external storage solutions, today expanded its My Book® family of external hard drives to include a 2 TB capacity, the largest available capacity in a single-drive system.

If the 4 TB My Book is unavailable, or if its price goes up, WD’s 4 TB Elements desktop drive is a great second choice. It’s a reliable drive, although it isn’t quite as fast as our top pick.
