WD is combining two high-speed technologies to produce one of the fastest dual-storage systems ever offered. Supported by the Mac OS X operating system, the new My Book VelociRaptor Duo dual-drive storage system becomes provides speed and performance with two 1 TB 10,000 RPM WD VelociRaptor drives along with two Thunderbolt ports. This boost in performance delivers data transfer rates of up to 400 MB/s, according to WD. The dual-drive storage system offers RAID 0 for performance or RAID 1 for protection; and the twin Thunderbolt ports offer daisy-chaining multiple My Book VelociRaptor Duo drives and other high performance peripherals without impacting data transfer speeds or performance. The My Book VelociRaptor Duo also comes complete with a Thunderbolt cable in the box and is user-serviceable.

While RAID 0 maximizes the drive's speed and capacity, RAID 1 support allows users to create a second copy of their digital content on the drive for added protection, security and peace of mind. The drive also provides a JBOD (just a bunch of disks) option for users running a Windows operating system on a Mac.

Additional features found on the My Book VelociRaptor Duo dual-drive storage system include out-of-the-box compatibility with Apple Time Machine and HFS + Journaled for Mac computers; capability for multi-stream workflows; and a 3-year limited warranty.
