The actual byte programming isn't the majority of the time taken; the "erase sector" command is. (This remains true even on modern SSDs and USB sticks and the like). On typical flash of that vintage, it can take a full second or more to erase a block, and you must erase each block prior to programming it. The System 573 games' setup process got an order of magnitude slower when smf put in proper erase timings, and I don't imagine it did CPS-3 any favors either.
