The My Passport Pro from Western Digital (WD) is the first portable, Thunderbolt-powered, dual drive solution. It's targeted to creative professionals and enthusiasts such as photographers, videographers, musicians, graphic designers, and architects.

For Mac systems, My Passport Pro has user-selectable RAID functionality to deliver performance for demanding applications in the field, without the need for power adapters or extra cables. My Passport Pro is available in 2TB and 4TB capacities.

Directly powered via the integrated Thunderbolt cable — a design unique to WD — the performance of My Passport Pro clocks in at speeds up to 233 MB/s, providing fast transfer, edit and backup capabilities. Another key feature of the dual-drive My Passport Pro is its user-selectable RAID function, which lets users choose data striping (RAID 0) for high performance or mirroring (RAID 1) for data redundancy, depending on the user's needs.

The integrated Thunderbolt technology of My Passport Pro provides the ability to copy a 22 GB high-definition video file in half the time typically required by a USB 3.0 drive working in RAID 0 format. Consisting of two 2.5-inch hard drives housed in a sleek aluminum enclosure, My Passport Pro has been shock-tested.

It's available at Apple and major consumer electronics retailers and e-tailers as well as online at www.wdstore.com. Pricing for the 2TB My Passport Pro is US$299.99, and the 4TB model is $429.99.
