We took the following scores using MSIs 845 Pro2 (845 chipset) and VIAs P4BX (P4X266A) motherboards with this same SCSI-RAID.

With the MSI motherboard the RAID-0 sequentially reads data with up to 114 MBytes/s. This performance is maintained over nearly the whole capacity of the RAID: the minimum speed only drops to 106 MBytes/s. Even with burst transfers from the cards cache we found the same results.

This looks much worse with the VIA motherboard. Our RAID there only delivers a maximum of 72 MBytes/s with sequential reads. Although the system also sticks with this speed over almost the whole capacity, a lot of the potential of the RAID is wasted. To be more precise: If you spend more than 2300 Dollars for a RAID system like this, you loose 34 per cent of the performance when this RAID has to deal with a VIA chipset.

Even with everyday tasks the differences are shuttering. If you copy a file of 2 gigabytes on the RAID systems, the Intel solution finishes 30 per cent faster then a VIA motherboard.

Even if this is not a matter of PEBCAK, I don't think it would effect those of us who don't have a 114mb/s raid array on our computers. Thats at the point where its near the limit of normal PCI transfer speed anyway.
