The conclusions are interesting that heat and usage is not a very good predictor of failure.. I guess basically the take-home message is what we all suspect: failure of disk drives is unpredictable - so backup your stuff regularly!

Heat and usage might not be absolutes, but in my humble experience with a much more limited amount of drives than google

, excessive heat and the kind of disk usage where there's a lot of head movement (ie, fragmented files as opposed to long linear unfragmented) reads/writes) do wear down drives faster.
