> Stan you are wrong on that... You are correct. I was wrong. Let me fix that with a two word edit: SSD life has increased substantially in the 3-4 year period since. Overall useful life of an SSD (the whole device) has continued to increase substantially thanks to better wear leveling controllers and RAISE, even though individual flash cell life has continued to decrease as process geometries continue to decrease. -- Stan
