Storage giant Seagate have introduced a USB 3.0-powered Backup Plus for Mac which is available through Amazon right now, and will be made available through the Apple Stores in November.
Both the Backup Plus Portable for Mac, and Backup Plus Desktop for Mac both sport the SuperSpeed USB 3.0 connectivity, which is of course backwards compatible. Seagate provides their Backup Plus devices with a software feature that lets them backup content from social networks like Facebook and Flickr.
Seagate Backup Plus Portable drivers will ship in 500GB and 1TB sizes for a MSRP of $109.99 and $129.99, respectively. The Backup Plus Desktop drives will be made available in 2TB and 3TB for $129.99 and $179.99, respectively.
