USB3.0 standard provides ten times the USB 2.0 transmission speed and higher energy efficiency, can be widely used in PC peripherals and consumer electronics products. USB3.0 interface theory bandwidth to 5Gbps, and USB2.0 theoretical bandwidth is 480Mbps. All the high-speed USB2.0 devices to get USB3.0 will have a better performance.


the main difference


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


2. Low power consumption (20% less power consumption than USB 2.0) at 20MB / s of data transfer;


3. USB3.0 more energy than 2.0, for the temporary waiting for the state of the device, you can use the power saving mode;


4. USB3.0 can provide greater power through the cable (2.5W upgrade to 4.5W);
