That's fine for mp3 players and cameras; even wrong. at 1 million writes (which better flash drives can do) wear leveling, this can be disproved with a simple back of napkin calculation... the major problem with flash drives in the server space is actually random write performance...if random write performed as well as random read for flash ssd, you would be able to replace a stack of 15k sas drives with a single flash ssd in terms of iops. merlin ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
