    Interesting article here about flash memory cards, their internal controllers and hackability.

    The security aspect is scary enough, but I do like the thought of using a small card as a standalone microprocessor for light projects...

    The hard part is identifying which controller you have for a given card and begging able to exploit it.

    VERY interesting. Also explains the "64GB" cards that have only 32GB or 16GB in them.

    That's a good story, which actually leads to this article.

    Apparently he was involved in Chumby production in China, and were having problems with fishy SDs from Kingston. And it talks about buying SDs from the SEG market in Shenzhen, well that's something I've done myself. LOL.

    With manipulating the micro-controller in SDs, that's how they do the phonys. Specifically the ones that might state 32 or 64GB and appear to the OS as that capacity, but in reality perhaps they're only 1-2GB.
