If you look in brakets it says (2000Kb/s) which means kilobits per second as opposed to 2000KB/s which would be kilobytes per second, but on the other hand it gives two values (of which I was going by the second, asuming it was the right one, but that was also labled Kb). But on the other hand, the value in brackets is probably actually the estimated overhead.
But to the point, 20000Kb/s (Kilobits per second, divided by eight to give KiloBytes) is 2500KB/s, which in turn is 2.44MB/s (divide KiloBytes by 1024 to get MegaBytes a second). So, yes, I was right.
2.44 MegaBytes a second.
