Kingston has announced that the DataTraveler Vault - Privacy Edition is now fully compatible with Macs.

The "ultra secure" hardware-based encrypted USB drive does not require any Windows software installation prior to use.

The drive features 256-bit AES hardware-based encryption and locks and reformats itself after 10 unsuccessful login attempts.

For added protection from clumsiness the USB drive comes in a protective aluminium casing and is waterproof up to 4 feet.

Prices range from £53.45 for the 2GB model to £445.38 for the 32GB version.
