a larger block size of 16k will probably be faster. i wouldn't expect it
to be too fast, though reads should be faster. if your application calls
for reading 512M of data regularly, maybe compact flash isn't the best
solution. most people i know using compact flash only boot from it, and
rarely touch it after.
