I am thinking it may be a waste of time as the sata speed is significantly higher than the pci speed. Also I would probably be a waste of time buying a pci card as I will probably upgrade my motherboard some time when i'm not stingy and then I will have to buy a pci-e card to get sick performance.
Does it work like this, if you had a pci-e x 16 you could put a pci-e x8 device in it at it would just run at the slower speed as there physically the same slot right?
One would have to wonder why they make sata pci raid cards.
