Synopsys has demonstrated world's first USB 3.2 transfer. The latest USB specification promises twice the bandwidth of USB 3.1 Gen 2 with speeds up to 20 GBit/s. During the demonstration that speed was not achieved.
Nevertheless, Synopsys achieved a whopping 13 GBit/s on Windows 10 using an USB Type C cable. The company claims to be the first in the world to have demonstrated USB 3.2. It did so through an USB connection between a Linux computer configured to run as an USB mass storage device, and a Windows 10 laptop configured to be the host. Synopsys stresses that there were no modifications to the drivers and that USB 3.2 will work with currently available drivers.
Specifications of the latest USB standard were released in autumn 2017 and several companies, such as Synopsys, are now working on the implementation. Although speed is doubled compared to USB 3.1 Gen 2, the new standard doesn't require new cables. To prove that, Synopsis performed their demonstration with a regular Belkin USB Type C cable.
Theoretically it should be possible to achieve 20 GBit/s with USB 3.2. However there is some overhead, so the 13 GBit/s achieved by Synopsys is likely close to the maximum real-world possible transfer rate.
The speed of storage devices become an issue with these speeds. To fully take advantage of USB 3.2, the client needs to be just as fast. External SATA 6 GBit/s devices become a bottleneck at these speeds.
