Why not use the mobo raid sata ports? They are probably faster than a controller on the pci bus. What kind of pci bus do you have? PCI-E 1x is likely to be too slow for a 4-drive raid10,f2 array. My 4-drive raid10,f2 delivers about 320 MB/s and newer disks should be able to deliver 360 MB/s - well above the 250 MB/s that a PCI-E 1x can deliver. > 2.
