SSD Write Endurance 25nm Vs 34nm

[Christopher]

Perhaps it's a warranty consideration? I mean, the 830 exhausted its MWI 180 days ago. It's written 4.5 more petabytes since then, so while Anand's statement doesnt fill me with confidence, it wont keep me up at night. But if they set the warranty length by MWI... It makes more sense. You also have to think that keeping 20nm flash within error specs is hard after a little bit of wear, so the reduction in MWI could be to keep uBER in check. The enterprise spec from JEDEC is 10^16, I don't know what the consumer spec is, but maybe it goes out of spec after a few thousand PE cycles (and isn't so much an endurance issue).

I actually read the review, and I think there is merely something wrong with the FW. I've had two drives both ship with MWI less than 100. In one case it was FW, and in another it was just caused by reallocations out of the box.
