USB 3.0 to Bring 10x Speed Increase in 2008

Intel discusses its plans for USB 3.0 technology

During Patrick Gelsinger's keynote at the Intel Developer Forum (IDF) today, Intel made a small announcement regarding a group of companies who are now working together to create a "superspeed personal USB interconnect” with 10 times the speed of the current generation technology of USB 2.0. The USB 3.0 Promoter Group -- which consists of Intel, Hewlett-Packard, NEC Corporation, NXP Semiconductors, Microsoft and Texas Instruments -- looks to make several other major changes.

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.
