I doubt that anybody knows the true cause of the 8mb bug (not even intel engineers).
But anyway, Windows 7 should automatically optimize settings for SSD (disable defrag, turn off indexing, enable trim, etc), so all you need to do is run WEI.
edit: fixed link. gave vista instruction by mistake.
Intel engineers must know the cause of the 8MB bug.... how else would they be able to issue a firmware to fix it?
