When using a flash-based system, it really helps to use a filesystem 
specifically designed for flash.  JFFS2, as used in the OLPC, uses a special 
block allocation scheme and garbage collection that allows it to spread wear 
evenly across the entire flash device.  It also uses on-the-fly compression.

As far as atime is concerned, I always turn it off.  It doesn't tell me 
anything useful about my files, slows disk performance, and wears drives out 
faster.
