The SecureData SecureDrive KP USB is a unique solution to keeping sensitive data safe. The main allure of this drive is hardware-based encryption. The drives contents will not appear in your operating system until you have unlocked the hardware encryption with the physical keypad. You can use the keypad to enter a user-defined PIN number that unlocks the drive and exposes its contents to your operating system. This is a very attractive solution for people who transfer highly sensitive data regularly and need a quick and easy way to do so.
