The My Book Duo offers enormous storage capacities and is ideal for storing photos, videos, documents, and music. The RAID 0 mode provides super-fast sequential read speeds of up to 360 MB/s (maximum speed when connected via USB Type-C). Switch to a RAID 1 setting with data mirroring if you want to store your data redundantly on the built-in WD Red hard drives. The USB Type-C port and the various included cables make the device universally compatible (supports USB 3.1 Gen 1, USB 3.0, USB 2.0). Additional USB devices can be connected to the two USB 3.0 Type-A expansion ports.
