USB3: why it's a bit harder than USB2

by Volker Weber

A few people on twitter have asked me to explain why the USB3 winds up being much harder to implement than USB2. The answer is more than will fit in a single tweet, so I thought I'd put a quick-but-rough answer, here. ... A lot of the challenges come from the way we work around physical-layer limitations. Put poetically, physics gives us lots of little obstacles we have to work around in order to talk at 5 billion transfers per second (5GT/s).

Fascinating challenges. Read the whole post.

Fascinating. One "fix" on top of another. I think I just learned that good cables will make a difference.
