There’s nothing revolutionary in it, but it delivers a solid value, Windows backup software and a 4TB capacity which is the highest available in a single hard drive. This edition of the Western Digital My Book Essential is an incremental bump to an established line of external hard drives. For 4TB of storage intended to be used primarily for backup and archiving that sells for around $200 at most retailers, this is a good value. The large-block random access speeds were 49.8MB/s for reads and 50.8MB/s for writes. The drive registered 126.1MB/s on sequential write and 127.4 MB/s on sequential read tests.

We tested the unit using the PC consumer testing platform using IOMeter over USB3.0. The only other features that break up the plastic are a tiny white activity LED on the front of the unit just above the small WD logo. The small part of the back panel that isn’t a vent sports a USB3.0 port, the power connector port and a power switch. As a result, the case stays cool to the touch. The entire top and bottom edge, as well as most of the back edge, is actually a vent.

The left, right sides and curved front “spine” of the My Book are formed by a seamless solid piece of plastic. A welcome feature of the enclosure is generous ventilation. It can be set vertically or horizontally, but the presence of rubber feet only along the bottom edge suggests that vertical is the preferred orientation. This edition is encased a glossy jet-black plastic enclosure. It shares the now-familiar stylized book shape that gives the line its name. The exterior of the WD My Book Essential hasn’t changed significantly since the line was first introduced.
