For chess this should not mater. RPM doesn't really affect bandwidth. In fact, the fastest spinners actually have lower sustained bandwidth because clocking the bits becomes a problem. As a secondary issue, the fastest disks are not the best capacity drives, for the same reason. Best SCSI drives for capacity today are the 7200 and under drives... > >>c).Does the new 915 chipset make the rpm slower?
