The USB (Universal Serial Bus) Promoter Group has completed and released the new USB 3.1 specification, which will double the existing speed of the SuperSpeed USB.

usb 3.1The existing USB 3.0 operates at 5 Gbits per second, 20 times faster than USB 2.0, and has a higher bandwidth compared to its predecessor. With the new USB 3.1 enhancement, the SuperSpeed ports will double on its existing speed and operate at 10 Gbits/s.

The new enhancements to the USB 3.0, USB 3.1 specifications released today, was announced back in January 2013 and was said to have improved data encoding and backward compatibility with existing cables and connectors along with the increased transfer speed.USB 3.1 can be downloaded from the USB implementers forum (USB-IF), the body that manages USB specifications.

“The USB 3.1 specification primarily extends existing USB 3.0 protocol and hub operation for speed scaling along with defining the next higher physical layer speed as 10 Gbps,” said Brad Saunders, USB 3.0 Promoter Group Chairman.

The USB Promoter Group consists of 6 leading technology companies, Hewlett-Packard, Intel, Microsoft, Renesas Electronics (Formerly NEC), ST-Ericsson (Formerly ST-NXP Wireless) and Texas Instruments.

The USB 3.0 was announced back in 2008 and the first consumer devices with the new standard started trickling into the consumer market during late 2009. Inspite of the fact that the USB 3.0 ports are backward compatible, these ports have been slow at gaining traction. Even today most motherboards still come with USB 2.0 along with the USB 3.0 ports. The USB 3.0 ports can be identified by their blue colour.

Windows 8 was one of the first operating systems to provide in built support for USB 3.0, but the new ports were marred with complaints of operating at slower transfer speeds.
