In the Read test results above, the Revo64’s RAID 3 once again falls somewhere between the competing RAID 1 and RAID 0. However, what is surprising are the NVIDIA buffered scores.

Write tests show something very different. As I’ve stated previously, RAID 3 benefits sequential reading and writing, and the data above shows this fact admirably despite being handicapped by the PCI bus.

NVIDIA’s RAID 5 on the otherhand shows some really poor performance. As we’ll see shortly, there is something bizarre happening on that end.
