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? Cheers,
Point being that they have to lower the bit density on high RPM drives to fit within the bandwidth constraints of the channel. If they could just get their channel working at 3GHz instead of 2GHz or whatever, they'd use that capability to pack even more bits into the consumer drives to lower costs. -- Eric D.
