A PIN on the keypad: protection that does not depend on the computer
A built-in rechargeable battery lets you enter the PIN before the drive is plugged in, so malware on the computer has no way to capture the keystrokes. The circuitry is covered in epoxy that destroys the components if removed, and the casing shows signs of tampering. Ten wrong user PINs lock the drive; ten wrong admin PINs in a row crypto-erase it for good. Digitally signed firmware protects against BadUSB attacks.
