The GoFlex Slim performance drive is the optimal capacity addition for portable devices with limited storage. The ultra-thin anodized case not only helps resist against damage while transport, it also adds a unique and premium finish to the drive. It is about as thick as a pencil, allowing you to slide it in a computer case, backpack or pocket so you can take your content anywhere and everywhere. The GoFlex Slim is not only thinner than most external drives, it also offers 5400 RPM performance and USB 3.0. The faster drive speed takes full advantage of the included plug-and-play USB 3.0 interface, allowing for up to 10x faster transfer speeds. USB 3.0 is backwards compatible with USB 2.0 (at USB 2.0 speeds), offering further interface flexibility. Install the pre-loaded NTFS... Less
