SuperSpeed USB (USB 3.0) co-developed by consumer electronics, semiconductor and software companies, provides faster transmission, higher usability and reduces energy consumption. By 2016, devices equipped with USB 3.0 are expected to reach 2.1 billion globally. The transmission speed of USB 3.0 on PC, smartphones and tablets can be as fast as 5 Gbps. The technology has been largely promoted by more than 200 companies, including big ones like Intel, Microsoft, Texas Instruments, HP, and Ericsson. They have been working to establish a brand-new USB transmission standard that aims for higher speed, less energy consumption and higher usability.
Compared with USB 2.0, USB 3.0 is improved in several aspects. First, the highest transfer rate at 5 Gbps is 10 times faster than that of USB 2.0. In terms of energy efficiency, USB 3.0 takes only 30% of that of USB 2.0 while sending the same number of data. In addition, it takes of half of the time needed when used as chargers.
For general users, the improved usability of USB 3.0 is the most easily felt and they do not need to worry about wrong directions of interfaces. USB 3.0 can be used on both sides, while UBS 2.0 cables are also applicable on devices supporting USB 3.0.
USB 3.0 is expected to become widely used between 2014 and 2016, with devices supporting the technology estimated to surge from about 684,000 to 2.1 billion in 2016.
