USB 3.0 Finally Arrives

BY Melissa J. Perenson, PC World

When you're in front of your PC, waiting for something to transfer to removable media, that's when seconds feel like minutes, and minutes feel like hours. And data storage scenarios such as that one is where the new SuperSpeed USB 3.0's greatest impact will be felt first. As of CES, 17 SuperSpeed USB 3.0-certified products were introduced, including host controllers, adapter cards, motherboards, and hard drives (but no other consumer electronics devices). Still more uncertified USB 3.0 products are on the way, and they can't get here fast enough.

And this time around, the way the USB spec is written, says Jeff Ravencraft, consumers should have an easier time finding products that are truly USB 3.0. Before, in the transition from USB 1.1 to USB 2.0, the USB 2.0 spec was written in a way where it "encompassed low, full and high-speed USB," explains Ravencraft, president and chairman of the USB Implementers Forum. "Since those are all encapsulated in the USB 2.0 spec, [vendors] could have a certified product that's low-speed, but still call it USB 2.0.
"We don't have that issue with USB 3.0 To claim you're USB 3.0, you have to deliver 5Gbps. There's no other way to get the certification."
Ravencraft adds that the group is prepared to protect the USB 3.0 logo, to make sure that only manufacturers who go through certification use it. "We'll take legal action if anyone infringes on our marks."
By end of year, Ravencraft says the loggerjam of products awaiting certification should be past, and the organization's network of worldwide test labs will be handling USB 3.0 certification.
According to In-Stat Research, by 2013, more than one-quarter of USB 3.0 products will support SuperSpeed USB 3.0.
Ravencraft says this is the fastest ramp up of USB products he's seen in the past ten years, across the previous versions of USB.
I say the change can't come fast enough. The trick, though, will be getting the interface into our notebooks (without requiring a kludgy ExpressCard adapter). So far, though, only HP and Fujitsu have announced limited USB 3.0 support on notebooks. And Taiwanese notebook and desktop maker MSI indicated that it wouldn't have USB 3.0 until, at the earliest, the third-quarter of this year; product managers for both notebooks and desktops cited manufacturing concerns like chipset availability in large quantities, and the need to test USB 3.0 chipsets.
And in the meantime, the only announced peripherals remain storage devices. At next year's CES, it's likely we'll hear more about specific consumer electronics devices such as digital cameras and camcorders and video cameras moving to USB 3.0. Hopefully by then we'll start getting a critical mass of PC hardware with USB 3.0 integrated, too.
