Question, What about the use of just RAM alone for read/writing? dont write to the SD card until the floppy gets the eject command therefore the entire disk image gets written, plus saving the SD card write cycles. would this work? Of course i understand if a power failure occured or something it could be tragic, but what are the odds... Then there is the whole part of battery backed RAM so if a PF does occur, the FPGA can look and see that there was a disk image last mounted, to go ahead and do an emergency save function.
