Am I mistaken in thinking that it's actually the outter edges of the 
platter that reap the highest performance. Imagine if you run in a 1 
metre circle in 1 second, and then "push out" a little further to, say, 
3 metres, but you must still travel this distance in one second so 
you're going to go faster. The outside of a hard disc platter must 
travel more quickly to stay with the inside of the platter, thus 
increasing the the head travel. Also more data can be stored 
consecutively in the larger outside margins of a platter. I ain't got 
nothing to back this up, and can't give anything scientific, so I can 
well understand if I am misplaced in my assumptions.
