No, the SSFDC module implements a software "Flash Translation Layer"
so that Linux can treat it as a block device. The filesystem is still
(probably) FAT, like you might use for USB flash drives or SD memory
cards. You can read a little more on the  Linux-MTD website. Ignore
the stuff specifically about UBIFS (a different filesystem for flash)
and note that xD memory is like the "raw flash devices" mentioned:

BTW, if you want a response from specific individuals (e.g., me), it's
usually a good idea to Reply-All so that the e-mail address appears in
To/CC.
