Unless you can show that the power requirements (current draw) of one
drive exceeds that of another, any conclusion that the drive is dying
because IT generates more heat is bogus. However, some laptops subject
the drive itself to [much] more heat (from the laptop, not the drive)
than other laptops. And some drives may be more sensitive to heat than
other drives, rotational speed not withstanding.
I have no interest in proving any points. I've made a pretty simple
correlation between the upgrading of the drive and the loss of 2
different brand drives in 15 months (one brand new, and one that had
worked in a T30 laptop for several years - I'm just waiting for the
next one to go now) and an overall higher sensitivity of the laptop to
heat.
Definitely not proof of causation, and it's only a few data points,
but they're data points that I have a great deal of faith in, for
obvious reasons, and I'm providing this data to the online community.
What you and others do with it is up to you.
While I could continue to gather data for years to come, I'm looking
at lower RPM/lower power drives instead. Tilting at windmills can be
pretty entertaining, and I've done my share of it, but purposely
gathering failure data on a working (and obsolete) laptop is not my
idea of a good ROI.
YMMV, as always. Feel free to post links to opposing data, as I'm
always open to changing my mind with quality data.
