Just to confirm -- why do you say "[Opteron] will have 2X as many disks"? In the dual-Opteron setup above I have 2 hard disks with RAID1, whereas in the single-Xeon quad-core setup I have 4 disks with RAID 10.
What I was trying to suggest was that the 3Ware system with the Intel Quad-Core processor would likely be faster than the Dual Dual-Core Opteron system even with the same number of disks because of how much faster its controller is, and the fact that the 3Ware+Intel system has twice as many disks just increases how much faster I'd expect it to be.
