High Speed Raid Solution

[Formula383]

I currently am running a silicon image raid0 setup on 2 wd 40gb drives.
I get about 85BM/s
I would like to use 3-4 250gb SATA drives in raid5 and get 100-130MB/s
With out having to go to a server board for pci-X
Can anyone give me any info or any suggestions on how to achieve this?

RAID5 is often slower than RAID0 unless you are throwing a lot of spindles at it.
And if you're not going with a PCI-X or PCIe controller, then you are limited to the 133MB/s max that a PCI bus can handle. Not including overhead, or any other devices on the same bus, or solar flares, or a strong headwind.

Its not going to happen on PCI. I ran into that brick wall with my 4 drive raid5 theory. The bus for PCI is too limited. I'll have to wait for a cheaper PCI-e mobo/controller

i guess i would have thought that someone would have had some actual information (numbers) on what is a fast raid 5 card......
