The My Book series from Western Digital has been on the market for some time now. This is due to its timeless, elegant design as well as its technological features. The Duo model has its name from the two integrated hard disk drives, which can be used in different RAID configurations according to the respective use. Either for a maximum speed, highest data security or a combination of both elements. The unambiguous software makes configuration child’s play and helps everyone – from computer novice to power user – to get an optimal performance from the external drive. With capacities between four and 12 terabyte, the My Book Duo also fulfills the requirements of demanding users.
