This Hard Drive Secure made by Freecom is probably one of the most secure hard drives out there. It uses an AES-encrypted RFID keycard which grants you access to everything inside. Swipe the card once to unlock it and swipe it again to lock it. The external hard disk drive isn’t available for purchase just yet but when it will come out you’ll be able to choose between a 500GB version and a 2TB version. Just make sure you have the extra $119 or $409, respectively, before getting your own Hard Drive Secure!
