The MTBF for the disk is given as 1000000 hours, while most other ...........snip There are not many hours in a year, so 3 years is little compared to 10^6 hours. (That 114 year MTBF is quite impressive.) It does though halve for each 10°C rise above the temperature at which the lifetime is predicted. Would the converse hold true ie. doubling for each 10°C fall bellow the temperature at which the lifetime is predicted? and
