Sorry, the topic was SSD, not SD. SSDs have controllers that contain heavy
closed magic to circumvent all kinds of troubles you get when using classical
flash and SD cards.
Honestly I would just drop the idea of an SSD option simply because the
vendors implement all kinds of neat strategies in their devices. So in the end
you cannot really tell if the option does something constructive and not
destructive in combination with a SSD controller.
Of course you may well discuss about an option for passive flash devices like
ide-CF/SD or the like. There is no controller involved so your fs
implementation may well work out.
