Having said so much, U disk USB2.0 What is the difference between the interface and the usb3.0 interface? Let’s introduce the difference between

U disk usb3.0 and 2.0

1. Slave transfer rate

The theoretical transmission data of USB2.0 is 480M per second, while the theoretical speed of USB3.0 is as high as 5G per second.
