I noticed that Plextor SSD drives have a MTBF of 1,500,000 hours. From what I know, MTBF is mean time between failures, I think. So it basically means the average amount of time that a drive will last before the hardware fails, right? That turns out to be like 171 years !
So to me thats a long time- i want to know how can that value be determined, I mean obviously the drive hasn't been tested for 171 years. Is that a calculation based on the average amount of use a SSD would experience compared to the known life of the NAND memory used in the SSD? What MTBF does other SSD drives carry, is it similar in length of time? Is the MTBF a good measuring stick to determine how reliable a SSD will be, if not, what would be the best way to tell that?
