Cryptography doesn't do you any good if there are guys with a car battery asking you very pointed questions, like "where did you get this encrypted disk"?
With MicroSD in your mouth, they wont even get the idea to question you.
We didn't exactly give bin Laden a lot of time to answer any questions. We found him and shot him. Encrypted documents would have remained safe after his death, but that MicroSD would be a goldmine of information that will compromise his other operatives.
I was addressing the transportation step of the message, not its long term storage. From OBL to net-cafe, the dude carrying it would be safer with a MicroSD, encrypted or otherwise.
