These two parts can be snapped onto each other to form a portable hard drive. The adapter part has a male SATA connector and a Mini-USB 3.0 port. The hard drive is a 2.5-inch SATA internal hard drive housed in a plastic chassis that has a small opening on one side to reveal the internal hard drive's standard SATA female connector. The drive comes in two parts: the hard drive and the adapter. The new Seagate Backup Plus comes from the same concept as the portable drives in the Seagate GoFlex family.
