i4u has a review on the PlexusCom BioDisk USB flash drive. The device has a fingerprint sensor on the top and can be directly plugged into your USB port or with an extension cable. The drives come in sizes of 64MB to 1GB and is a great way to protect your sensitive data files. It would be nice to integrate it with Windows Login, but unfortunately this is not supported yet.
