disk drive manufacturers spec their "max" operating temp,
and does NOT mean you can run at that temp 24x7x365
the disks are warranted for 1,000,000 too .. but we're not worried
about that?? and we only care about their 1year warranty ( 6,000hrs )
the life of the disks dies at a rate of 1/2 life cycle
for each 10C increase above 25C at "normal" operating condition
which could be "for use only for 2 hrs of the day" or something
silly ( everybody knows, laptop disks are not meant to be
used 24x7 )
> Where did you get the 30 C maximum from?
my 7200rpm disks all runs at that temp range or less
( excluding scsi )
