WD 4TB My Book Thunderbolt Duo with Thunderbolt Cable B&H Kit

The 4TB My Book Thunderbolt Duo with Thunderbolt Cable B&H Kit is a kit that includes a My Book dual-drive storage system with two Thunderbolt ports (capable of up to 10 Gb/s data transfer rates) and a Thunderbolt cable as well, so you can start using those blazing transfer rates right out of the box.

The system supports user-selectable RAID 0 (striping) and RAID 1 (mirroring) modes, as well as JBOD (Just a Bunch of Disks) modes for both backup and storage needs. Plus, since Thunderbolt ports are bidirectional, they afford high-speed multitasking. You can also daisy chain multiple devices or peripherals using the two Thunderbolt ports for better efficiency and productivity. For added convenience, the drives are user-serviceable and the system comes with the WD Drive Utilities software.
