[QUOTE="RavingMac, post: 1474277, member: 45350"] And, to attempt to give my layman's explanation on how a 250GB 5400 RPM drive could be faster than a 100GB 7200 RPM, the rationale goes like this. 1) The 7200 drive spins 33% faster than a 5400 drive, so all else being equal it would be 33% faster on data handling but 2) Each revoloution the head encounters 2.5 times as many data bits on the 250 drive as the 100 drive due to higher storage density. So the net of that is the 5400 RPM drive is potentiallly faster than the 7200 RPM drive because of the difference in storage density. [/QUOTE]
