The Western Digital WDBUSK0080JSL 8TB My Thunderbolt Duo is a dual-drive storage system with two Thunderbolt ports capable of up to 10 Gb/s data transfer rates. The system supports user-selectable RAID 0 and RAID 1 modes, as well as JBOD modes. 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 Drives Utilities software. A Thunderbolt cable is included so you can immediately start operating this storage-system.


Move Data at Unprecedented Speeds

Video editors and other digital media professionals can do more work in less time thanks to the data transfer speed of the Thunderbolt ports on WD's My Book Thunderbolt Duo. It offers the fastest way to get information to and from your external drive

User-Selectable RAID or JBOD Modes

With the My Book Thunderbolt Duo, you can choose between RAID 0 (striping), RAID 1 (mirroring) and JBOD. RAID 0 offers the performance you need when designing or editing time-sensitive graphic-intensive media files. RAID 1 provides safer data protection by automatically generating a duplicate copy of your data. JBOD allows you to use this dual-drive storage system as two individual drives and select between HFS+J or ExFAT per disk. It's ideal for running Windows OS on a Mac

Dual Thunderbolt Ports

Daisy chain multiple devices or peripherals such as HD displays, media players, HD media capture and editing systems using the two Thunderbolt ports, if you want to maximize your workflow efficiency and productivity

High-Speed Multitasking

The bidirectional Thunderbolt technology delivers heightened speed for multitasking while video editing, 3D rendering and completing other graphics intensive projects


To replace a drive, just open the case and exchange the existing drive - no tools needed. If you fill up a drive, you can remove it and replace it with a fresh drive and begin saving even more of your work
