For a large block random access Reading and Writing speeds were 49.6 MB/s and 72.3 MB/s respectively. For Sequential Reading and Writing, the My Book topped at 137.4 MB/s and 136.1MB/s respectively – which is a fantastic result. We used CrystalDiskMark to test out the performance of the hard drive.

The best way to gage the performance of a hard drive is by doing a stock standard speed test. When the drive went to sleep, it was virtually silent. During reading and writing there was only a small noise of the hard drive spinning but nothing loud. There are rubber feet on the bottom of the My Book suggesting that it should be placed upright, however, we found the My Book to work fine in both Vertical and Horizontal orientations. You’ll find a USB 3.0 port, power port, power button and Kensington lock port on the back. The spine of the My Book is a vent from the hard drive inside meaning the My Book doesn’t really get that warm, even after several hours of continuous use. Now featuring a jet black glossy finish and white activity light at the front, you really can’t go wrong with it’s design. The design of WD’s My Book range has remained mostly the same over the years, however, the design of the hard drive has changed slightly.

The included software SmartWare will also allow you to format the drive to HFS+ when installed on OS X. The drive is pre-formatted with NTFS – for use with Windows computers, however, the drive can easily be formatted to the file system of your choice. Designed for use on a desk, the My Book comes with a huge 4TB of space, USB 3.0 connectivity and a small form factor so it can be placed almost anywhere. Enter, the My Book Essential drive from Western Digital. With those that have USB 3.0, getting the right drive to take advantage of those great speeds is important.
