What are the differences between USB 3.0 and USB 3.1?

The main differences between USB 3.0 and USB 3.1 lie in transmission speed, power output, interface design, and functionality support.

Transmission speed:

The maximum theoretical transmission speed of USB 3.0 is 5 Gbps.
The maximum theoretical transmission speed of USB 3.1 has been increased to 10 Gbps, which is twice that of USB 3.0, providing a more smooth and efficient high-speed transmission experience.
Power output:

The power supply standard of USB 3.0 is 5V/0.9A, with a maximum power of 4.5W, suitable for most ordinary USB devices.
USB 3.1 supports up to 100W of power output, which can meet the charging needs of higher-power devices, such as laptops and large-sized mobile hard drives, making the USB interface more flexible and powerful in terms of power transmission.
Interface design:

USB 3.0 uses the traditional Type A and Type B interfaces.
USB 3.1 introduces the Type C interface, which supports reversible insertion, improving the convenience of use and having stronger data transmission and power transmission capabilities. The Type C interface also supports multiple protocols, further expanding its functions and application scenarios.
Function support:

USB 3.0 mainly supports data transmission and device power supply.
USB 3.1 adds support for USB A/V audio-video transmission, enabling the USB interface to connect to display devices such as monitors, achieving the transmission of high-definition video signals. This function is particularly important for professional users who need multi-screen display or video editing.
