The motors spin twice as fast?
I'm pretty sure the original comment was based on drives w/ similar
specs. E.g. 7200RPM "enterprise" drives versus 7200RPM "consumer" drives.
Next time one of my 7200RPM SCSIs fail, I'll take it apart and compare
the insides to an older 7200RPM IDE from roughly the same era.
