well the Databook claims Ichigo's Bankai from the SS arc is Lightning fast.. which could be interpreted as him just being really fast and used more in a metaphorical way, or you could say he moves at the speed of lighting.. and considering his gotten way faster over time, he should at least be a few thousands of times faster than Sound.
