"As far as we've seen, the Flash Padlock 2 delivers on its promises: the PIN locking and unlocking system works, the drive doesn't even register on a host system when locked, performance seems very acceptable, and the enclosure can take plenty of punishment."
There are plenty of drives out there with 256-bit AES encryption, but very few have an active lock/unlock mechanism in form of a number pad or fingerprint reader. The latter requires active power, having to connect the stick first and then swiping your finger using a software stored on the flash drive itself. This offers various ways to attack the protection to gain access to the stored data. Corsair has gone with the unattached PIN entry with no software required to be run on the host system. This means that there is no way to bypass the system. It is a mystery to me, how Corsair manages to give the user instant access when using VBE, but if that is true, the entire flash memory is encrypted. Even if one opens up the unit and de-solders the flash storage IC and then accesses the data, all the hacker will find is encrypted data.
