USB 3.0, or SuperSpeed USB technology, is expected to see broad adoption across a range of PC and PC peripherals over the next several years.

This is according to a new In-Stat report, which stated that SuperSpeed USB will be targeted initially at devices requiring high data transfer rates and large data stores, such as external HDDs and flash drives. Other likely target devices include portable media players, LCD PC monitors and digital still cameras.

The market research firm projected that attach rates for SuperSpeed USB will soar to over 70 percent in external hard-drives by 2012, with similar attach rates in notebook and desktop PCs. Initial adoption will emerge in 2010. By 2013, shipments of USB 3.0 flash drives will approach 200 million units worldwide. Eventually, mobile phones will be the highest volume segment, simply due to the overwhelming volume phones shipped. Overall, SuperSpeed USB will represent over 25 percent of the USB market by 2013.

"SuperSpeed may eventually move beyond those target applications requiring the highest bandwidth." says Brian O'Rourke, In-Stat analyst. "However, in order to achieve broader adoption, cost will have to go down significantly. To get SuperSpeed USB costs down and increase attach rates, the technology will have to be integrated into the ASICs, and SoCs, that power the peripherals."

With over three billion devices shipped in 2008 alone, USB is the most successful interface ever. It has been broadly adopted across PCs, PC peripherals, consumer electronics, communications and automotive devices, In-Stat said. The firm also forecasted that digital TVs with USB will grow to 140 million units shipped in 2013, while CE devices with USB will rise at a 6.6 percent CAGR between 2008 and 2013.
