The My Book Duo drive has massive capacity for storing photos, videos, documents and music. RAID-0 mode provides super-fast performance with up to 360MB/s2 sequential read speeds (using the USB Type-C™ port). Switch to RAID-1 configuration for redundancy and to mirror data on the WD Red drives inside. A USB Type-C port with all cables included makes it universally compatible (supports USB 3.1 Gen 1/3.0/2.0). Two USB 3.0 Type-A hub ports deliver flexibility for additional accessories.
