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 drives. Thanks to RAID-0, it is ready for use by default with maximum speed and capacity. The included WD Drive Utilities software also allows for the setup of a RAID-1 array for redundant storage or to use it as two independent drives (JBOD). The My Book Duo is equipped with two RAID-optimized WD drives and is an ultra-fast, high-quality storage solution you can rely on. The RAID-optimized firmware ensures data integrity during read and write operations in the dual-drive configuration. The My Book Duo drive features 256-bit AES hardware encryption and WD Security software, keeping your private content safe and confidential. Set your own password to enable hardware encryption and data security.
