Aegis Padlock hardware encrypted portable drive
I reviewed the 750GB model of the Aegis Padlock (there are four lower capacity models available as well, starting at 250GB). The keypad on the Padlock lets you assign your own six- or twelve-digit pin for accessing the device. And the drive offers your choice of 128-bit or 256-bit AES hardware encryption. The drive remains encrypted even if removed from its enclosure.
