Would this mean that it is unlikely we will get an ON-time faster than 500ms? Or will your newRPL eventually yield faster ON times?

Thank you.

Yes, it seems the utilities for MAC follow the much older recommendations you linked (funny how the same information from the same source varied over the years). For embedded systems, I like the old specs better, as less clusters means less overhead.
Did you check the cluster size on the other card? If you formatted with the same utility, then it should be at 4kbytes. If that's true, your 256 MB card has a FAT 4 times bigger than the other one, yet still starts in the same amount of time? (head scratching...)

Regarding newRPL, it doesn't suffer from this until you use the card. ON is (and will forever remain) instantaneous, it's a revolutionary design concept once used in devices of the 20th century, that apparently was abandoned by millennial developers :-).
If you've been following the newRPL thread, we already have a compromise solution that will eliminate the mount delay even on large SDHC cards. I'm testing it now, will be out soon.
