原创 SuperSpeed USB - How fast is it actually?

I have seen a number of articles mentioning SuperSpeed IP sales and  various performance numbers (only theoretical).  I would like to use  this platform to inform the users the actual speed achieved on USB 3.0 Development board by IP designers at SLS

The  core efficiency is dependent on a number of factors like 8b/10b    encoding, packet structure and framing, link level flow control and    protocol overhead.

At   5Gbps signalling rate with 8b/10b encoding, the raw throughput is    500MBps.  When link flow control, packet framing, and protocol overhead    are considered, it is realistic for 400MBps or more to be delivered  to   an application.

Various tests performed with SLS SuperSpeed USB core on GigaByte A75 Motherboard have indicated the performance ~2.1Gbps  with mass storage interface and ~2.7Gbps with raw interface.

Any other experiences with the speed/performance of SuperSpeed cores are most welcome!
