FusionIO is publicly claiming 24 years @ 5TB/day on the 80GB SLC device, which wear levels across 100GB of actual installed capacity.

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.
