The Vrap on SATAII will be fine

to follow up..

Motherboard onboard controllers (SATA/SAS) do not allow the same performance as a professional card on a PCIe 4/8 slot. They work well however they lack buffer ability.

If I was going to spend money on SAS I would not use a onboard SAS system.

In compare of a Vrap to SAS on a professional card controller for FSX use, both the SAS and Vrap would deliver data at speeds which would not hinder performance and in many cases be faster than the VC+CPU+MEM could process a complicated scene.

SAS is overkill for FSX, A single VRap is not going to fall behind. 2 Vraps in RAID0 on a professional controller card would equal SAS in performance and would also be overkill for FSX


you also have to be careful when buying SAS. Just becasue its SCSI based does not mean its faster. Todays SAS can be lower RPM than 10-15K SCSI drives of the past so just becasue a drive is SAS does not mean its faster than a VRap.
