Ok, sorry I'm getting OCD, but seeing as this is a tech subforum on a tweaker site, it should be one of the few places to ask this: If I have 2 raid controller cards, running 2 raid arrays, lets say A and B, A containing the C partition and B containing the D partition, would I take a performance hit due to the fact that both array A and B reside on PCI Controller cards that are sharing the PCI bus? Would it be faster to just use 1 array controller card for programs and video editing temp storage, and plug the other HDD running the main OS into the main IDE controller of the mobo? To add to my worries, I want to add a SATA2 controller card to the pci bus as well to control my DVD burner and another SATA HDD. I guess it all depends on whether or not the PCI bus will be a bottleneck on data writes/reads on the devices attached to PCI cards.
after quick reading/research, it seems pointless to run raid0, in the name of performance, over a PCI bus. I would be better off using single drives on the onboard controllers for 1.5GB/sec IDE bandwidth and just save my money at this point.
