My board is PCI-X for all 6 slots or I can use PCI 64/66 for all slots. I am looking for cards that are not slow on this. I have got a working system with Promise PATA controllers that can read in software RAID 250 MB/s in sustained read and more than 150 MB/s random read. I am looking for same speeds with SATA drives and controllers. Thanx for the answer Milan Roubal
