Plus, there's the issue of how hard you're driving each.
Letting the SATA drives sit mostly idle will probably yield
skewed results in favor of SATA when compared to SCSI drives
are driven so hard that the array they are in are bound to
melt a hole in the datacenter floor. I don't think anyone
is suggesting to run your "interesting" loads on ATA disks.
