Non Card based directly managed flash chips with file systems like JFFS2 
and UBIFS that handle the wear leveling in the file system code itself

wear leveling into account and (maybe) it even can be rolled back clean 
to the last transaction completely stored on the flash ship.

stored data when storing of other data is aborted.

I was even told about cards that could not even be formatted after an 
aborted write (obviously the writing to a a page management page has 
been aborted.) It was completely dead but _could_ be reconfigured by the
