Am I correct in thinking that a SATA controller would be easier and faster to

Is it anything more than a parallel to serial and serial to parallel converter. a DMA controller, and the line transceiver?

If we were going to market an X server on a card, this would good to include since it would give the X server direct access to the disk for a swap partition without going through the computer -- only arbitrate on the bus on the card.


   An enhancement for OGA-2, perhaps?  It could get complicated; the graphics
card might have to buffer all requests coming from the computer on that
interface and arbitrate priorities.

The PCI bus extends onto the card and different devices are different PCI devices so arbitration occurs just the same as the main bus but if both are on the card, then arbitration doesn't leave the card.
