The difference between USB3.0 and USB2.0

1. Data transfer rate, 3.0 is SuperSpeed 5.0Gbps, 2.0 is 1.5Mbps, 12Mbps or 480Mbps

2. Data interface, 3.0 is full-duplex, four-channel differential signal independent of USB 2.0 signal, supports simultaneous two-way data transmission, 2.0 is half-duplex, dual-channel differential signal, one-way data transmission, the total route needs to be negotiated in advance Transmission direction

3. Number of signal lines, 3.0 is 4 SuperSpeed data lines, 2 HighSpeed data lines and 2 power and ground lines, 2.0 is 2 LS/FS/HS data lines, 2 power and ground lines

4. The data bandwidth of USB3.0 is ten times that of USB2.0, which can reach 5Gb/s (480MB/s), and the synchronous transmission bandwidth can also reach 384MB/s. This is one of the main differences between USB3.0 and 2.0;

5. Low power consumption (approximately 25% lower power consumption than USB2.0 when the data transfer volume is 20MB/s);

6. USB data cable 3.0 is more energy-efficient than USB data cable 2.0. For devices that are temporarily in a waiting state, you can use the power-saving mode;

7. USB3.0 can provide more power through the cable (2.5W increased to 4.5W);

8. USB3.0 is backward compatible and supports USB2.0 devices, but USB2.0 cannot support USB3.0.
