USB 3.1

USB 3.1

In January 2013 the USB group announced plans to update USB 3.0 to 10 Gbit/s (1250 MB/s). The group created a new USB specification, USB 3.1, which was released on 31 July 2013, replacing the USB 3.0 standard. The USB 3.1 specification took over the existing USB 3.0's SuperSpeed USB transfer rate, now referred to as USB 3.1 Gen 1, and introduced a faster transfer rate called SuperSpeed USB 10 Gbit/s, corresponding to operation mode USB 3.1 Gen 2, putting it on par with a single first-generation Thunderbolt channel. The new mode's logo features a caption stylized as SUPERSPEED+; this refers to the updated SuperSpeedPlus protocol. The USB 3.1 Gen 2 mode also reduces line encoding overhead to 3% by changing the scheme to 128b/132b, with a raw data rate of 1,212 MB/s. The first USB 3.1 Gen 2 implementation demonstrated real-world transfer speeds of 7.2 Gbit/s.
