ops I was thinking .1S... you mean .1mS!!! therefore (even if flash 
was fast enough. IT IS NOT) you will basically kill the chip in 10 
seconds.

How much data are you saving? you can use 512 MB MMC card and save 
the new data without deleting the old ones till needed! Again, it 
depends on how much data is going there.
