Intel talks USB 3.0 at CES
LAS VEGAS--At the Consumer Electronics Show, Jeff Ravencraft of Intel talked about the status of SuperSpeed USB 3.0 and how fast it really is.
The most salient benefit of SuperSpeed USB is the 10X improvement in data transfer speed over current USB, version 2.0. So, for example, transferring a 25GB HD movie will take 70 seconds instead of almost 14 minutes.
Transfer of a 25GB HD movie:
- USB 1.0: 9.3 hours
- USB 2.0: 13.9 minutes
- USB 3.0: 70 seconds
In the video below, Ravencraft, who is president of the USB Implementers Forum, discusses the merits of SuperSpeed USB and the schedule for commercial rollout.

I'm surprised that there's over a 9-hour time difference when transferring 25GB between USB 1.0 and 2.0...maybe I just forgot how slow the process was a few years ago, though.
