I did/do consider it. It's just that I have never used SD cards before.
>From a distance, they appear a bit "high-tech" to me (though I
understand they feature a simple SPI interface ?), whereas I am more
familiar with old-school Flash chips, so I tried to go this route
first. But since this is proving more and more of a dead end sadly, I
will have no choice but turn to SD cards. I just hope they are not (too
much) more work to read/write than Flash chips already are
(page/bloc mess, long writing times, long and funny command sequence
to get them working...) :-/
I guess it's time I go hunt the 'net for some SD card datasheet to see
what's involved exactly... crossing fingers it's not too
difficult/overwhelming, mmmm...
