USB 4 standard developed

The new standard will enable to transfer data with the speed up to 40 Gbit/s.

It was reported at the forum on USB development that the work on USB 4 technical standard was completed. In the near future the specifications will become available for engineers, designers and device manufacturers. The initial devices with a new connector will appear in 2020.

The main advantage of the new protocol is, of course, the speed. The 4th version of the USB protocol will transfer data at a speed of up to 40 Gbp/s, which is twice as fast as USB 3.2. On this indicator, the new connectors will be on a par with Thunderbolt 3.

The new standard was developed by the non-profit organization USB-IF. The USB 4 connector will be produced in a Type-C form factor and will be backwards compatible with USB 3.2 and 2.0 and Thunderbolt 3. So now all devices with a Type-C connector can be connected via USB 4.

Before USB 4, many users were unhappy that Thunderbolt 3 devices are usually more expensive and less popular. USB 3 devices are much more common, but are significantly slower than Thunderbolt 3 devices.

USB 4 will allow to unify the connectors in such a way that it does not affect the speed.
