Well, here is the deal.
As it turns out, the motherboard I bought has just one PATA connection. The rest are SATA. My thinking was, ok get a PATA DVD and SATA Hd's.
Well, turns out this PATA connector is really managed via some other driver. Without the motherboard RAID driver installed, it will only allow PIO, no DMA. Transfer rates suck. So, I installed the RAID driver and now transfer rates are good but DAE is maxing out at 12x - still much lower than I would want.
BTW, once you install that driver, you no longer see the connection that the CD/DVD is on listed in the device manager under IDE connections. So, I guess I'm going to buy a SATA DVD.
