You might be thinking of the Arrhenius relationship, which some manufacturers use to model life stress of semiconductor components. Temperature can cause other failures: affecting fluid bearings, drying out of heat sink compound, and so on. But failures are also influenced by the thermal cycling range of the components, not just by the absolute temperature, since the cycling is what causes stress fractures in wire and solder bonds. I have seen failures in (spinning) hard drives which were running in over-temperature conditions, but only with extremes (60°+). A large scale Google study showed that over normal temperature ranges (up to about 45°), failure rate can actually reduce with temperature. It would be interesting to see a similar study on SSDs. http://static.googleusercontent.com/media/research.google.com/en//archive/disk_failures.pdf Glenn -- sks-keyservers.net 0x6d656d65
