I've come across hard drives with it, and I'm curious as to just what it is. Is it supposed to be fast? Or, is it just like some sort of power saving thing? Would it be faster than a regular 7200 rpm hard drive? Thanks in advance for your answers.
Powersaving.
Looked that up for awhile, everywhere I look it seems to be people thinking it adjusts the speed between 5400-7200rpm to optimise cache usage and to optimise power consumption, so in short. I don't know.
