L'USB 3.0 Promoter Group, il consorzio dedicato allo sviluppo della revisione 3.0 dello standard USB, ha reso noto di aver definito in maniera completa le specifiche di USB 3.0, anche indicato con la denominazione di SuperSpeed USB.
In accordo al comunicato stampa di Promoter Group, che include aziende di primo piano nel panorama internazionale come Hewlett-Packard Company, Intel Corporation, Microsoft Corporation, NEC Corporation, ST-NXP Wireless e Texas Instruments, SuperSpeed USB porterà con se un notevole boost delle prestazioni (per fissare le idee il data rate assicurato sarà fino a 10 volte superiore a quello di Hi-Speed USB ovvero USB 2.0, ndr), pur introducendo delle ottimizzazioni dal punto di vista del consumo di potenza. USB 3.0 è retrocompatibile con le precedenti revisioni dello standard, e dunque essenzialmente con USB 2.0, 1.1 e 1.0.
I primi controller USB 3.0 saranno pronti nella seconda metà del 2009 mentre i primi produtti orientati al mercato consumer e USB 3.0 compliant (e.g. flash drive, hard drive esterni, player multimediali e macchine fotografiche) saranno disponibili nel corso del 2010.
The USB 3.0 Promoter Group today announced the completion of the USB 3.0 specification, the technical map for device manufacturers to deliver SuperSpeed USB technology to the market.
SuperSpeed USB brings significant power and performance enhancements to the popular USB standard while offering backward compatibility with billions of USB-enabled PCs and peripheral devices currently in use by consumers. Delivering data transfer rates up to ten times faster than Hi-Speed USB (USB 2.0) with optimized power efficiency, SuperSpeed USB is the next step in the continued evolution of USB technology.
"SuperSpeed USB is the next advancement in ubiquitous technology," said Jeff Ravencraft, USB-IF president and chairman. "Today’s consumers are using rich media and large digital files that need to be easily and quickly transferred from PCs to devices and vice versa. SuperSpeed USB meets the needs of everyone from the tech-savvy executive to the average home user."
The USB 3.0 Promoter Group, comprised of Hewlett-Packard Company, Intel Corporation, Microsoft Corporation, NEC Corporation, ST-NXP Wireless and Texas Instruments, developed the USB 3.0 specification. The group now has transitioned the specification’s management to the USB Implementers Forum (USB-IF), the managing body of USB specifications. The USB 3.0 Promoter Group is now accepting adopters of the USB 3.0 specification, which has been finalized at the 1.0 level.

It is anticipated that initial SuperSpeed USB discrete controllers will appear in the second half of 2009 and consumer products will appear in 2010, with adoption continuing throughout 2010. The first SuperSpeed USB devices will likely include data-storage devices such as flash drives, external hard drives, digital music players and digital cameras.
The USB 3.0 specification debuted today in conjunction with the first SuperSpeed USB Developers Conference in San Jose, California. The conference provides attendees the first opportunity to hear directly from the creators of the USB 3.0 specification; keynote speakers will address advancements offered by the new technology. In addition to technical sessions, an exhibit area will showcase the latest developments and early designs featuring SuperSpeed USB technology. Attendees will obtain information on the best practices for incorporating SuperSpeed USB into their product roadmaps.
The USB 3.0 specification includes many advancements for both consumers and adopters, including higher speeds and enhanced power efficiency. For more information about the USB 3.0 specification, visit http://www.usb.org/developers.
