Why not simply make an SSD Controller that has a thunderbolt port? Since Intel is building thunderbolt into its support chips now, this seems like a good way to get quick performance, plenty of bandwidth without having to come up with new standard, separate drivers, etc. Thunderbolt ports could be put on motherboards fairly easily, etc. Is there something I'm missing? Plus this would have the advantage of driving down prices for thunderbolt and increasing adoption.
