There is no doubt that USB4 >USB3.2>USB3.0>USB2.0>USB1.1, the further forward the interface is, the better.

Since USB1.0 has basically been completely eliminated, we focus on USB 2.0 and above.

Generally speaking, USB2.0 is mainly black and has a maximum transmission rate of 480Mbps; USB3.0 is mainly blue and can reach 5Gbps.

USB3.0 supports downward compatibility with USB2.0, which means that USB3.0 devices can be plugged into the USB2.0 interface for use. However, to fully utilize the transmission speed of USB3.0, you still need to use the USB3.0 standard port.

Or the other way around, insert a USB2.0 device into the USB3.0 interface. Although it works normally, the data transmission will work at the speed of the USB2.0 interface.

If it is a usb3.0 interface and is also a USB3.0 device, but the speed is no different from USB 2.0, then something is wrong. It is possible that the 3.0 device is recognized as 2.0 by the computer!

USB2.0 has 4 pins on the front; USB 3.0 also has 4 pins on the front, but there are 5 pins on the back. These pins are used for signal detection.

If the speed of inserting the U disk is too slow, the computer will capture the USB 2.0 signal first, but will not receive the subsequent USB 3.0 signal, so it will recognize the USB 3.0 device. into USB 2.0.

In other words, inserting the USB disk too slowly will also cause the transmission speed to slow down. Doesn’t it sound a bit incredible, or even funny?

Some netizens did a test for this, deliberately slowing down the speed of inserting the USB flash drive, deliberately allowing the computer to recognize it as a 2.0 USB flash drive, and then transferred the file for testing.

The data obtained shows that a video of about 6G takes about 12 minutes.
