Y'know - i never thought about that before...  as the data density goes 
up, the data read/write rate would go up as well - regardless of the 
platter staying @ 4200 rpm...  or 5400...

so even if the platters aren't spinning any faster, the data, being at 
a much higher density, is whizzing past the read head way faster...  
and with those platters being so tiny...  i bet that that data on a 
60Gig 4200rpm 2.5" drive is read even faster than the data on a 60Gig 
3.5" 4200rpm drive...

makes sense, but is it true?
