What is the difference between the USB3.0 data line and the USB2.0 data line?

 With the rapid development of hardware performance, more and more people prefer USB 3.0 data line. So what is the difference between USB 3.0 data line and USB 2.0 data line? In this regard, Xin Yu Xin summed up the following points:

 
1, USB3.0 compatible with USB2.0.
 
 
2. The maximum transmission bandwidth of USB 3.0 is as high as 5.0 Gbps (640 MB/s), while that of USB 2.0 is 480 Mbps (60 MB/s).
 
 
3, USB3.0 can transmit large capacity files (such as HD movies) at the storage rate defined by memory devices. For example, a USB 3.0 flash drive can transfer 1GB of data to a host in 15 seconds, while USB 2.0 takes 43 seconds.
 
 
4, USB3.0 introduces full duplex data transmission. The 2 lines in its 5 lines are used to send data, and the other 2 are used to receive data, and 1 are ground wires. That is to say, USB 3.0 can read and write at full speed synchronously, but previous versions of USB did not support full-duplex data transmission.
 
 
5. Apparently, the USB 3.0 data line is thicker than the USB 2.0 data line, because the USB 3.0 data line has four more internal wires than the USB 2.0 data line.
