USB data speeds doubled to 10Gbps with new spec from major players

Major companies have announced the availability of a 10 Gigabits per second USB technology.

The USB 3.0 Promoter Group, which consists of HP, Intel, Microsoft, Renesas Elect, ST Ericsson and Texas Instruments, has announced the availability of the USB 3.1 specification to take SuperSpeed USB to 10 Gbps.

SuperSpeed USB 10 Gbps uses more efficient data encoding and will deliver more than twice the effective data throughput performance of existing SuperSpeed USB, over enhanced, fully backward compatible USB connectors and cables.

The USB 3.0 Promoter Group said compatibility was assured with existing USB 3.0 software stacks and device class protocols, as well as with existing 5 Gbps hubs and devices and USB 2.0 products.

The 3.1 specification is available to download from the USB Implementers Forum website. The non-profit USB Implementers Forum was formed to provide a support organisation and forum for the advancement and adoption of USB (universal serial bus) technology.

Brad Saunders, USB 3.0 Promoter Group chairman, said, “The specification team worked hard to make sure that the changes made to support higher speeds were limited and remained consistent with existing USB 3.0 architecture to ease product development.”

Tom Bonola, chief technology officer for business PC solutions at HP, said,“We recognise this advancement in USB technology is an important development for our customers. The USB 3.1 specification enables us to meet the growing needs of our customers for faster data transfer while maintaining backwards compatibility with existing devices.”

The forerunner USB 3.0 specification was released in November 2008.
