The Freecom Mobile XXS Drive may be small in size, but with 1TB of storage it's ideal for large data backups and transfers. With a USB 3.0 connection, it offers SuperSpeed data transfers - and it's also back compatible with USB 2.0. A tough rubber enclosure provides a comfortable grip when carrying the drive. Just plug it in with the included USB cable and you're ready to go - there's no need to connect an external power adapter.
