is about SD cards and what's dangerous about them. But what you can do
with SD cards you can do with SSDs and USB sticks too, I would say.
And think about removing data what's in bad blocks. I think it's not
possible to remove that data without destroying the SSD. An SSD could
even copy all your data to hidden parts.
I would like SSD's without a controller, where the OS is reponseable for
bad-block mapping and wear leveling. Or SSD's with open source firmware.
See here a list of the tasks of the processor in a SSD:
