The thing is that OCZ decided to revise the maximum number of erasing operations for flash memory and reduced it by 50% from 10 000 to 5 000 (we think they did it just to be on the safe side). And since the reliability and wear of an SSD is calculated depending on these figures, the estimated lifetime in S.M.A.R.T. parameters changed as well. Honestly getting information over from the drive manufacturer to the user, SSDLife just showed this fact :)
