Progress is inevitable and we definitely need that kind of speed. Its not only about hard drives but also about Audio visual components. Such as an USB HDTV Dongle which is a bit slow for USB 2.0. It is also one of the reasons why webcams currently max out at 2.0 megapixels. anything more than that the current USB 2.0 cannot handle. It is quite easy to eat through those 600MB/s, Just think of the USB 3.0 replacing 1000mbit ethernet.
