Recently, the specification of USB-IF announced that it has completed the development of the USB4 specification and provided new details about the standard, which means that engineers can already get started, and Mac users should be aware Some places that I have met before.

Based on CNET Reports, USB4 will provide 40Gbps bandwidth, which is twice that of USB 3.2. Of course, it is not easy to achieve the speed of USB 3.2. Many computers still in use today are still early. The USB standard can only support up to 5Gbps or 10Gbps.
