Features: 1. Full-duplex data transmission. In USB 3.0, 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 periphery 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, meaning USB 3.0 can perform full-speed read and write operations synchronously. The previous USB version does not support full-duplex data transmission. 2. Ultra-fast transmission speed, USB 3.0 is also known as SuperSpeed USB, which greatly improves bandwidth, up to 5 Gbps full duplex or 625 MB/S, but the actual transmission speed is about 3.2 Gbps, or 400 MB/S, USB 2.0 It is 480 Mbps half-duplex, meaning 60 MB/S. USB 3.0 can transfer a number of files (such as high-definition movies) at the storage speed limited by the storage device. 3. For example, a flash drive using USB 3.0 can transfer 1 GB of data to a host in 15 seconds, while USB 2.0 It takes 43 seconds. Supports USB 3.0 (5 Gbps), compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) specifications. 4. Supports Windows 2000/2003/XP/Vista/WIN 7SP1, Linux, for IOS.
