TechNews: Are you Ready for USB 3.0?

Intel and others are planning to release a new version of the ubiquitous Universal Serial Bus technology for quite sometime now. A revamp the chipmaker said will make data transfer rates more than 10 times as fast by adding fiber-optic links alongside the traditional copper wires.

Intel is working fellow USB 3.0 Promoters Group members Microsoft, Hewlett-Packard, Texas Instruments, NEC and NXP Semiconductors to release the USB 3.0 specification.

In an interview, Gelsinger said there’s typically a one- to two-year lag between the release of the specification and the availability of the technology, so USB 3.0 products should likely arrive in 2009 or 2010. A prototype shown is working now, and USB 3.0 will have optical and copper connections “from day one,” he added.

The current USB 2.0 version has a top data-transfer rate of 480 megabits per second, so a tenfold increase would be 4.8 gigabits per second. Many devices don’t need that much capacity, but some can use more, including hard drives, flash card readers and optical drives such as DVD, Blu-ray and HD DVD. The fastest flash card readers today use IEEE 1394 “FireWire” connections that top out at 800 megabits per second.

In addition, USB 3.0 will offer greater energy efficiency, Gelsinger said. It will be backward compatible, so current USB 2.0 devices will be able to plug into USB 3.0 ports.

    Hello, I’ve found your blog from LinkReferral. I guess comments down here would be more valuable at LinkReferral. Anyway, you have got a nice blog with rich contents. Though the right side bars looks a bit congested maybe can try to organize them a little bit to look more tidy and neat.

    Keep up the good job dude!
