If you're in constant fear that your data will be compromised for one reason or another, you'll be pleased to hear Apricorn has just outed their Aegis Padlock Secure Hard Drive.
This portable storage system actually has a keypad with which you can enter a PIN number you set. This way, no one else can access your information without that specific PIN you designate.
Other features include a USB 2.0 cable, AES-128 or 256 bit encryption, ten user IDs and a single administrator to assign permissions, and an omnidirectional shock mounting system, allowing the device to stand up to unexpected bumps. You can get the Aegis Padlock Secure Hard Drive now in 250GB, 320GB and 500GB capacities in either 128-bit or 256-bit versions. Pricing is $100, $110 and $140 for the 128-bit models and $120, $130 and $160 for the 256-bit ones.
