FusionIO is publicly claiming 24 years @ 5TB/day on the 80GB SLC device, which wear levels across 100GB of actual installed capacity. http://community.fusionio.com/forums/p/34/258.aspx#258 Max drive performance would be about 41TB/day, which coincidently works out very close to the 3 year warranty they have on the devices. FusionIO's claim _seems_ credible. I'd love to see some evidence to the contrary.
