5,000,000,000 bps / 8 / 1024 / 1024 X 0.8 = 476.8 MB

作者4.4.11 Efficiency

SuperSpeed efficiency is dependent on a number of factors including 8b/10b symbol encoding,
packet structure and framing, link level flow control, and protocol overhead. At a 5 Gbps signaling
rate with 8b/10b encoding, the raw throughput is 500 MBps. When link flow control, packet
framing, and protocol overhead are considered, it is realistic for 400 MBps or more to be delivered
to an application.

USB 3 spec (http://www.usb.org/developers/docs/...spec_022412.zip)
其中 USB3_r1.0_06_06_2011.pdf實際上是跨不了 400MB 大門的
畢竟USB是一對多的架構，本來就是較SATA的點對點複雜
