The worst thing that I fear of about flash drive is not faulty Flash drive but losing it, the valuable data that stored in the flash drive could be access by anyone that get hold of it. Corsair’s Flash Drive Padlock provides a hardware-secured lock to protect data on an USB drive. Featuring auto-lock hardware, it will self lock after removal from computer.
This prevents any unauthorized access or “Brute Force” attack to the data on Flash Padlock. Users can program in a PIN, much like they do for an ATM machine, to lock/unlock their data. An easy to use keypad in conjunction with lock/unlock indicator lights makes the Flash Padlock highly intuitive to use. Lastly, the Flash Padlock is fully plug-and-play, and requires no software or drivers to work properly. Corsair Flash Padlock comes with 1G or 2G each cost $29.99 and $39.99 respectively.
