Features: 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 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 USB3.0 can perform read and write operations at full speed simultaneously. Previous USB versions do not support full-duplex data transmission. 2. Ultra-fast transfer speed, USB3.0 is also known as SuperSpeed USB, which greatly improves bandwidth, up to 5Gbps full duplex or 625MB/S, but the actual transfer rate is about 3.2Gbps, or 400MB/S. USB2.0 is 480Mbps half-duplex, which is 60MB/S. USB3.0 can transfer large numbers of files (such as high-definition files) at the storage rate limited by the storage device. 3. For example, a flash drive using USB3.0 can transfer 1GB of data to a host in 15 seconds, while USB2.0 takes 43 seconds. Supports USB 3.0 (5Gbps), compatible with USB 2.0 (480Mbps) and USB 1.1 (12Mbps) specifications. 4. Supports Windows 2000/2003/XP/Vista/WIN 7SP1, Linux, for iOS.
