<pre wrap="">The situation with RAID hard drives is fairly straight-forward: buy the
enterprise versions - eg. Seagate 750 ES. These have MTB of around
3,000,000 hours which is over 300 years and are only a bit more
expensive.
But there is just one primary rule for any HD: KEEP THEM COOL. Drives go
very quickly if you let them overheat. You can actually buy any old
rubbish so long as you follow this rule.

<pre wrap="">I would think so as well, but:
The Google paper on hard drive reliability seemed to contradict this
seemingly common sense idea.
They were unable to show much of a correlation between temperature and
failure rates.

If you read the paper and looked at the pretty graphs I don't think you
would say that. The temp range IIRC was 20 - 50 degrees C. That's
hardly a "narrow range."<br>
