Uhm. Higher RPM = higher linear speed of the head above the platter = higher throughput. If the bit pitch (ie the size of each bit on the platter) is the same, then surely a higher linear speed corresponds with a larger number of bits per second?
So if "all other things being equal" includes the bit density, and radius to the edge of the media, then ... surely higher rpm => higher throughput?
