Micro-USB 3.0 type A and type B ports on iPhone

As the transmission speed of USB3.0 interface has been greatly improved compared with USB2.0, its pin has also changed. As a result, the Micro-USB3.0 interface had to change its appearance. The Micro-USB3.0 interface is the same height as the Micro-USB2.0 interface, but its length has increased significantly. Similarly, Type A and Type B appear on Micro-USB3.0... I really don't understand why the USB Society has to make small USB ports A and B every time, so I won't make fun of them here.

The micro-USB3.0 interface devices we contact most are high-speed mobile hard disks, most of which are Type-B Type.
