You're right that the BB has a smartcard reader, though the reliance on bluetooth makes it... problematic for use in the field. What I was trying to describe was something similar to what we currently use in laptops. Remove the card (express card in most cases, though they can be built onto the ssd themselves) and the computer is no longer able to read or write to the drive, as it never actually holds the FDE keys.
