It seems that we are in agreement that expected lifetime depends on the usage model. Lifetime will be vastly longer if the drive is used as a normal filesystem disk as compared to being using as a RAID write cache device. I have not heard of any RAID arrays which use FLASH for their write cache. They all use battery backed SRAM (or similar).
