I recently had some hard-drive problems and went to Altex to pick up a 
couple cooling fans, and a salesman there told me about a study done at 
Google on hard drive failures that sounds applicable.

They made a number of surprising conclusions that seems to contradict 
"conventional wisdom".  First, their server farms are filled with 
_consumer grade_ HDD's, and if that isn't a hard operating environment 
(given how much traffic they handle), I don't know what is.  But the one 
point that caught my attention was that elevated operating temperatures 
did not hurt reliability -- in actually helped ... up to a point.

If you're interested, the report is available at Google Labs.  Just 
search for something like "Hard Drive Reliability Study".
