I wrote a brief post about USB 3.0 back in September 2007. In less than two years, Linux becomes the first operating system to have a driver written for USB 3.0. Thanks to Sarah Sharp for her groundbreaking work. True to word, USB 3.0 transfer speed tops at 5 GBps. Expect USB 3.0 support to be included in future Linux kernels possibly by September 2009.
