The Corsair Flash PadLock is not built for durability but is designed just with affordable security in mind. The device is not water or shock resistant and is larger than most of the USB flash drives that we have seen. On the front of the drive are a combination keypad, locked and unlocked indicators, access indicator, and key buttons. The USB 2.0 port is concealed behind a small plastic cap.
The keypad contains five buttons with values from zero through nine. Inside the flash drive is a 3V lithium battery, which allows you to key in the pass code even while the Flash PadLock is not connected to a computer. Corsair's instruction manual is definitely helpful during the setup process for creating your own pass code. The locking mechanism for the Corsair Flash PadLock is hardware-based and platform independent. If the Flash PadLock is not unlocked via the proper pass code, the flash drive will not mount and thus the data is inaccessible.
