Karma Hard Disk Technology

I remember reading sometime back before the Karma was a reality, about the hard disk technology that would make the Karma possible. Something about it being shock resistant, low power, etc. I can't get my hands on that info anymore. My search techniques probably suck.

Does anyone know what type of HD is in the Karma's? Pointers to information about them or where they can be purchased (to use in a car pc).

Thanks.

It's a Hitachi disk drive. Read the end of this thread.

Thanks.
