The WD My Book is a basic no-frills backup drive. The slower 5400 RPM drive and USB 3.0 interface makes it ideal for data backup as transfer speeds are lower than drives that include faster 7200 RPM drives or faster Thunderbolt 3 interfaces. However, if you are not looking at intensive use cases such as editing 4K videos, then the performance should be perfectly acceptable. The design is pretty basic but the plastic case provides enough passive ventilation to keep it cool. The slightly cheaper Elements Desktop drives have a more basic design and negate the bundled backup software; however, they feature the same drives and performance. The 3 year warranty is better than the 1 year of the Seagate Expansion Desktop or the 2 years of the Seagate Backup Hub Plus.

Summary

The My Book are very similar to the Elements Desktop drives, only adding hardware encryption and bundled backup software. If you can do without these, the Elements Desktop is slightly cheaper. A 3 year warranty is longer than equivalent Seagate drives.
