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.

LAS VEGAS--At the Consumer Electronics Show, Wireless USB devices made an appearance en masse.

What does that mean exactly? Wireless USB notebooks, docking stations, hard drives. And more consumer-centric devices like Wireless USB speakers, displays, and USB phones. In fact, Samsung was showing a prototype mobile phone. (See photo below.)

"It looks and feels like wired USB, only it's wireless," according to Jeff Ravencraft of Intel, who is president of the USB Implementers Forum, speaking in an interview at CES.

Over 130 products have been certified, according to Ravencraft. "The next thing in Wireless USB is Wireless USB 1.1 where we're adding upper band support for a worldwide footprint for ultra-wide-band frequency, easier association of the device to the host, and more power efficiency," Ravencraft said.

At close range, up to 3 meters, Wireless USB delivers up to 480 megabits per second, he said. At this range, throughput is essentially the same as wired USB, Ravencraft said. Up to 10 meters, this drops to a maximum throughput of 110 megabits per second.

Ravencraft said there are wireless hard disk drives in the market now.
