Considering the competition in drive locking/encrypting, USB Secure has a very steep price of USD 29.95. There are many free alternatives, such as the powerful TrueCrypt, which offers AES, TwoFish and Serpent encryption algorithms (and their combinations like AES-TwoFish, TwoFish-Serpent etc.) USB Secure is well behind the price/performance comparison in the USB security arena. In addition, USB Secure, for its price is used only for external disks, where TrueCrypt can be used for any type of disks.
