Ironkey

Thumb drives are handy, but they're also super easy for a digi-thief to walk off with your important data. Offering military-grade encryption, the Ironkey ($79-$149) is here to stop those unsavory types. The metal flash drive is built to withstand software and hardware attacks — the main chip self-destructs, Mission Impossible-style, after 10 incorrect password attempts, making the drive totally unreadable. Choose from 1GB, 2GB and 4GB sizes.
