this is an example of an desktop ssd test:
http://uk.hardware.info/reviews/4178/hardwareinfo-tests-lifespan-of-samsung-ssd-840-250gb-tlc-ssd-updated-with-final-conclusion

and this is TLC! IMHO, at this moment, the reliability of ssds depends
less on the cell storage technology than of firmware quality .. i would
say that a pair of at least 120 GB ssds (raid1) are safe to use in
enterprise environments. (N.B. you would need at least 80k iops writes
at queue depths > 8)

HTH,
Adrian
