I was just wondering if anyone knows how to determine if the internal hard disk in the MP is running at 3.0gbps or 1.5gbps. From the system profiler, in the Serial-ATA tab, my machine shows that the intel controller shows a speed of 3.0gbps. My question is does that show the speed at which the hard disk is running? Or does it show the maximum speed the controller can achieve? So, is there any way to determine the speed the HD is running at from the profiler? If not, what's a good 3rd party app. (or whatever app) that lets you check the speed in Mac OS X? Thanks.
