One should note that environment seriously affects MTBF, even on non-movable parts, and probably even more on movable parts. I've talked to people in the reliability business, and they use models that say that MTBF for a part at 20 C as opposed to 40 C can differ by a factor of 3 or 4, or even more. A lot of people skimp on cooling and then get upset when their drives fail. I'd venture to guess that a drive that has an MTBF of 1.2M at 25C will have less than 1/10th of that at 55-60C. -- Mikael Abrahamsson email: swmike@xxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
