Is USB2.0 and USB3.0 universal?
Mar 27, 2018

The answer is yes.

1. USB2.0 devices will not be affected when accessing the usb3.0 interface.

2. The performance of USB3.0 devices will be reduced to USB2.0 when accessing USB2.0.

3 .The theoretical speed of USB 2.0 is 480Mbps=60MB/s and USB 3.0 is 4.8Gbps = 600MB/s. However, the actual transmission speed of the two is far from the theoretical speed, which is limited by the bottleneck of hardware such as the main disk drive.
