The USB 3.2 has just been announced and it will focus on increasing the speed of data transfer

The USB 3.0 Promoter Group, a working group that counts the main companies of new technologies and which is responsible for establishing the next USB standards, has just announced the arrival of the USB 3.2. This new standard will not change anything from the physical point of view to USB connectors, but will focus on improving data transfer speeds.

It is becoming increasingly difficult to navigate through the different USB standards. Between USB Type-C (which can be of type 2.0, as well as 3.0 or 3.1) and different standards (USB 2.0, 3.0, 3.1 Gen 1, 3.1 Gen 2), the neophyte can quickly be lost. And it surely will not deal with the arrival of USB 3.2 soon.

This new standard has just been announced by the USB 3.0 Promoter Group, a group in which we find the main players of the new technologies, starting with Apple, Microsoft or HP. It will not physically change our USB cables and ports, since it will focus primarily on performance.

A maximum bandwidth of 20 Gbps

Main innovation: the USB 3.2 will support solutions to several channels, in this case two channels of 5 Gbps or two channels of 10 Gbps. Concretely, this means that the USB 3.2 will double the data transfer speed compared to USB 3.1, since the maximum transfer speed of the USB 3.1 Gen 1 is 5 Gbps and that of the USB 3.1 Gen 2 of 10 Gbps. You follow ?

The problem currently with the USB 3.1 Gen 1 and Gen 2 is that to have their maximum transfer speeds, it is necessary to have very specific equipment, namely two devices equipped with USB ports Gen 1 or Gen 2 as well as a cable supporting such flow rates. In short, the planets had to be perfectly aligned to take advantage of this optimal performance.

The USB 3.2 should partially solve this problem by using the multi-channel capabilities of the USB Type-C. Two devices with USB 3.2 but connected by an “old” Type-C USB cable should have a bandwidth of more than 2 GB / s. In other words, you will not need to buy the latest generation of USB cables to enjoy a high transfer speed.

An integration that is not expected before the end of next year

The USB 3.2 is not ready to arrive. The specifications of the new standard will be finalized in September and its arrival on the various electronic devices is not expected before the end of 2018.
