Auto manufacturers try to predict how their interiors and their paints will last, too, but until both are subjected to the Texas sun they are only guessing. The North has salt that kills cars; in the South it is the sun. Only when they obtain empirical data can they be sure and that data takes a long time to gather. The same goes for optical media manufacturers. Any longevity rating is a SWAG, at best, which is the reason for my cynical view.
Sure. As anyone who's ever had a couple of hard disks fail can attest, MTBF numbers are mostly fiction.
Mean time between failure states the average time between to undetected read errors. This is completely unrelated to MTBB (Mean time between breakdowns ;) So de-facto MTBF doesn't tell you much. IMHO it's just good that the MTBF is usually much larger than the typical disk life time.
