The Seagate GoFlex Slim Hard Drive offers additional storage solution for portable devices with limited storage capacity. It has USB v2.0 connectivity and is formatted for Mac computers out of the box, making it fully compatible with Time Machine software. Its ultra-thin anodized case not only provides durability, 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 for convenience. This GoFlex Slim drive for Mac is compatible with GoFlex accessories, while giving you the option of upgrading to faster interfaces. Install the downloadable HFS+ driver on a PC and use the drive interchangeably between PC and Mac computers without any formatting and with no loss of performance.
