Is there actually any appreciable difference in cost?
Oh yeah, huge, twice as much or more on Ebay.
But, to answer your question, the PCI bus (assuming standard 32bit/33MHz) is limited to an aggregate theoretical 133MB/s, so even SATA150 can saturate the entire bus. Greg
That is what I figured, thanks, why would they make a PCI 3MB/s controller... just marketing?
