If you notice at the picture below, it looks thicker than your regular WD My Passport drive. It is thicker, why? Because not only does it feature a super-fast Thunderbolt connectivity, it also features two drive (meaning it’s a dual drive) that can be configured in RAID 0 mode, giving it an SSD-like speed, or in RAID 1 which is the mirror mode for double safe data protection. Check out the rest of its features and specs, price and where to buy below."
Western Digital My Passport Wireless Pro is not only for photographers, it's for everyone. Indeed, it's a really powerful personal cloud storage.
CNET Review: The WD My Passport Pro is fast, portable, and has some of the largest storage capacity you can find. It supports multiple RAID setups, has a well-designed built-in Thunderbolt cable, and is comparatively affordable.
