It's a borderline understatement to call Seagate's portable hard drive slim. At less than 0.5" tall when lying on its side, the hard drive has about the same thickness as a pencil. Yet these svelte dimensions house 500GB of storage for photos, videos, music, and other digital files. The preloaded Seagate Dashboard simplifies downloading and sharing files with integrated social media apps such as Facebook, Flickr, and YouTube. These functions work seamlessly with both Windows and Mac operating systems—no reformatting or shouting obscenities required. Mac users also get several added benefits, including out-of-the-box USM and Time Machine compatibility. This lets the hard drive begin automatically backing up files upon plug in.
