Quick: what’s more important? Your entire My Documents directory, or your Facebook / Flickr galleries? The answer seems fairly obvious, but for those too proud to admit it, Seagate‘s got a new hard drive that’ll delicately handle both. The outfit’s latest line of 2.5-inch mobile HDDs goes by the name Backup Plus, aiming to give consumers one-click backup and the ability to save and share your content on Facebook and Flickr. They’ll work interchangeably with both Windows and Mac platforms, and they ship with a new Seagate Dashboard interface that makes all of that “one-click magic” possible. The company’s proclaiming that these guys are the world’s first external drives to “provide backup for content on social networks, such as Facebook and Flickr,” with a single-click path to Save (download) and Share (upload) personal videos and photos. Backup Plus drives can be snagged in the US starting today, with Amazon, Best Buy and other reputable dealers offering ‘em in 500GB, 750GB and 1TB capacities for portable drives and 1TB to 4TB for Backup Plus Desk drives. Pricing and color details are spelled out in the presser just after the break.
