Small enough for a loaded laptop bag yet spacious enough for loads of content, the red 2TB Backup Plus Slim USB 3. 0 External Hard Drive from Seagate combines portability with useful file storage. Formatted as exFAT and compatible with Windows and Mac right out of the box, this drive connects to systems running Windows 7 and higher or macOS 10. 11 and higher using its micro-USB port and an included 18" micro-USB to USB Type-A cable that is compatible with USB 3. 0 and USB 2. 0. It is powered via the USB bus, which means that no additional power supplies are required, and also features plug-and-play functionality, meaning that no additional drives are required for use.
