SATA is saturated because the increase in performance between platter disks and SSDs is a big discontinuity in what had been a relatively slow but steadily rising curve in the max sequential speed of a disk. Right now SATA is playing catchup, and has had two fairly major iterations in a much shorter cycle than what used to be the case. SATA 6gbps isn't saturated by even the Vertex 3. Mobile bandwidth is a problem for completely different reasons - I wouldn't equate them.
