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/s 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.

Massive Capacity

The My Book™ Duo drive has up to 20TB capacity with a single cable. Free up valuable space on all your computers. Store and back up your photo, video and music collections, and important documents in one reliable place.

RAID-0 Ready Out of the Box

Ready to perform at maximum speed and capacity in default mode, RAID-0. Reconfigure the drive to RAID-1 for redundancy (data mirroring), or use it as two independent drives (JBOD) with the included WD Drive Utilities™ software.

RAID-Optimized WD Red™ Drives

The My Book™ Duo drive comes with RAID-optimized WD Red™ drives inside to deliver high-speed, quality storage to rely on. RAID-optimized firmware is perfect for two-disk array systems with auto management of drive operations to help ensure read/write cycle data integrity.
