I thought so too.
I always thought it works like a PCI Express Slot.
Just because it's bandwith is a certain number, doesn't mean that the card will work at that speed, it depends on the card, not the slot.
I think in a few years down the road the hard drives will be able to do 3gb/s and we will end up getting a new interface.
