Well here is one, but this is really for the device level: http://nepp.nasa.gov/workshops/etw2012/talks/Tuesday/T04_Heidecker_Flash_Qualification.pdf http://nep

If I find a good system-level paper, I'll post it.
Anyway, SSD drive wear tends to be rated like this: 5 years for x number of full drive writes per day. For good drives, x is 1. For really good SLC NAND based drives x could be as much as 10, but they are very expensive. For cheap consumer drives x could be 1/10. Based on vendor sales meetings, the aggressively large drives also have low write endurance (but then they say they are not optimized for heavy writes).
Better drives should have a built-in write counter so you can track the remaining life.
Another interesting parameter is their power-off "data retention" time. At end of life, this tends to be specified to be just 90 days.
