newwgg just had a m4 128gb crucial for $99 that I just grabbed as a second to the first one I bought and have the better part of filled.
I's cost averaged down now to just about $1/gb as I paid $160 at teh beginning of the year for my first one.
as they say, if I only knew then what I know now...

NAND is rated for a certain number of cycles and as it shrinks (from 55nm to 22nm, for instance) the number of cycles decreases. The controller also implements wear leveling algorithms with space set aside. Enterprise SSDs tend to have more NAND space set aside. Controllers also determine write amplification via their design.
