About USB 3.1 Specification

USB interfaces are commonly used in PCs, tablets, mobile phones and external storage devices. 
The new USB 3.1 specification was released by the USB Implementers Forum in 2013, and the first USB 3.1 10-Gb/s-capable products are expected to reach the market in 2014. 
The USB 3.1 specification more than doubles possible throughput compared with the USB 3.0 specification. This throughput improvement was achieved by doubling the physical data rate from 5 to 10 Gb/s and by changing the coding scheme from 8-bit/10-bit to 128-bit/132-bit, which requires significantly less overhead.
