Um, the difference is not to be concluded, merely measured.  I don't have
the data now, so it can't be weighted as more than hearsay, I'm
afraid.  The upshot was, testing showed lower RPM drives to have a
slightly longer MTBF, and a longer life-span before motor failure,
bearings, etc...

In any case, while statistically significant, it wasn't really real-world
significant (esp. considering price).

[Factor in environmental concerns, and I dislike the idea of 'just buying
a new one when it dies', but sometimes you can't afford to be too
principled... :(
