I do believe the PCI bus is too slow / loads the bus too much for SATA-2 
hard drives, which is why we can't get a controller for them. However, 
PCI-E X1 cards are available and drop into a PCI-E X1, X4, X8, or X16
slot, and handles SATA-3. (Provided the X16 slot has not been assigned 
to a graphics port by the Mfg.) A little off topic, but a newer system 
might be in order here. If someone finds a controller for old PCI, 
tho... let me know. I have MANY older Pentium 4 single cores. :)
