Encrypted storage device design

For quite sometime now I've been facing space crunch on my laptop and have been using various external storage devices. I'm reluctant to put any important piece of information on these devices due to security and privacy concerns. Unlike my laptop (and the disk within it), these devices will not be in my sight all the time and hence my reluctance to trust any confidential data with them.
I've thought about using some software based encryption solutions. But I need them to work seamlessly on multiple operating systems as these portable storage devices will be connected to different machines running different OSs.

I've been wishing for a crypto device that would sit between the computer and the portable disk and provide transparent encryption/decryption functionality. Such a device would have to be small. It can be powered from the computer over USB. It should have a biometric identification device embedded on it for authentication. One such device could be used to interface with multiple storage devices.

It would transparently work on all the popular OSs as it would present a standard generic USB storage device interface. Encryption/decryption should work at wire-speed.

I've searched on the Internet for my imaginary device and haven't come across one. If anyone knows of such a device, please do add a comment. Hope someone would manufacture it some day.
