Amazon offers the WD My Passport Pro 2TB portable RAID storage with integrated Thunderbolt cable for $199.99 shipped, which is $100 (33%) less than its regular price and by far the best deal we’ve ever seen. Most retailers are charging between $270-$290 for it.

This is not your average external hard drive used for making the occasional Time Machine backup. With features like an integrated Thunderbolt cable, RAID 0/1 or JBOD setup and speeds of up to 233MB/s, it’s geared towards professionals who are constantly on the move. The entire drive is powered via Thunderbolt (no AC adapter needed) and is protected by an anodized aluminum enclosure. Rated 3.8 out of 5 stars from 103 Amazon reviewers.
