Western Digital’s My Book Mirror Edition isn’t the thinnest external hard drive there is, but this is a virtue of containing two hard drives. Housed in a piano black casing with perforated top, bottom and rear for airflow and a glowing blue light on the front, it does its best to emulate the shape of a hard cover book — although we’d suggest it’d look slightly out of place on a bookshelf. Two versions are available: a 1TB model for AU$349, and a 2TB model for AU$699, both with a three-year warranty.
The Mirror Edition is the first external hard drive from the big player that is user serviceable — that is, you can open it up and replace the hard drives yourself, should one of them fail. This is done by pressing down hard on the top near the front to release a magnetic clamp, then turning a key to unscrew a support bracket, then using a plastic loop to remove the hard drives. While the manual did feature the procedure, it wasn’t intuitive and removal of the drives proved difficult, mainly down to the plastic loops which apply pressure to only one side of the hard drives and cause needless additional friction. Western Digital has a little further to go on the design front before user serviceable becomes user friendly.
