1. Full-duplex data transmission. In USB3.0, in addition to the 4 main lines, two sets of cables are added (each set has a pair of signal lines and ground lines, and the is shielded by aluminum foil, which does not interfere with each other) , one group is used to send data, and the other group is used to receive data, that is to say, USB3.0 can read and write at full speed synchronously. The previous USB version not support full-duplex data transmission. 2. Ultra-fast transfer speed, USB3.0 is also considered as SuperSpeed USB, which greatly improves the bandwidth, up to 5Gbps full-duplex or 625MB/S, but the actual transfer rate is about 3.2Gbps, or 400MB/S, USB2.0 It is 480Mbps half-duplex, that is, 60MB/S. USB3.0 can transfer a number of files (such as high-definition ) at the storage rate limited by the storage device. For example, a flash memory using USB3.0 can transfer 1GB of data to a host in 15 seconds, while USB2.0 It takes 43 seconds. 3. Support USB 3.0 (5Gbps), compatible with USB 2.0 (480Mbps) and USB 1.1 (12Mbps) specifications. 4. Support Windows 2000/2003/XP/Vista/WIN 7SP1, Linux, for IOS.
