Careful, you're mixing bits and bytes there. USB2 has a theoretical maximum of 480Mb/s (that's 480 mega bits per second) PATA has a theoretical maximum of 133MB/s (that's 133 mega bytes per second) 480 (bits) / 8 (bits per byte) = 60 Therefore USB2 has a theoretical maximum throughput of 60MB/s (but it's really nearer 55MB/s in the real world) (compared with 133MB/s of PATA), per host adapter.
