As a data container optimised for mobile use, the ThinkPad USB 3.0 1 TB external security hard drive combines ultimate data protection with handiness. 256-bit AES encryption ensures the security of the stored content. The housing is handy and light and has its own power supply. The high-quality integrated keypad allows you to enter an 8- to 16-digit password for... an administrator ID and a user ID, if desired. The security hard drive can be connected either via USB 2.0 or USB 3.0 or with the USB 3.0 cable housed in an integrated storage compartment. The ThinkPad 3.0 1 TB security hard drive is supplied with a USB Y extension cable that reliably supplies it with power - a separate power supply unit is therefore unnecessary. An attractive protective cover, also included in the scope of delivery, protects the hard drive during transport.
