While you’ll pay a premium, the GoFlex Slim is true to its name. This is the slimmest external drive we've laid hands on. It seems barely larger than a 2.5-inch standard laptop drive. In the package, a USB 3.0 cable and connector that's backwards compatible with USB 2.0. The Slim continues Seagate's interchangeable connectors concept meaning you can change the way your drive connects to the computer without having to buy a whole new drive. If you don't mind breaking the aesthetic of this super slim drive, you can even use the connectors from other not-so-slim FreeAgent GoFlex drives.
