When you say speed, do you mean actual rotations per minute or what?

To find the speed of a drive in your system. Go into system profiler then find the drive (normally under Serial-ATA) then find the drive model number. Look this number up and it will tell you the RPM. As for the ipod its a 4200 RPM ATA-66.
