Lexar today revamped its JumpDrive Secure II with the new Plus model. The USB stick continues to rely on the 256-bit AES encryption that automatically locks files on the drive and can securely erase them through a FileShredder function; new, however, is an e-paper storage display borrowed from the Mercury that displays the filled space on the drive without requiring a battery.

Any of the JumpDrive Secure II Plus models will work with both Mac and Windows PCs. The line ships immediately with capacities ranging between 512MB and 4GB. An 8GB version is expected to follow soon. Pricing hasn't been outlined completely but begins at $20 for the 512MB version.
