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, though the actual transfer rate is about 3.2Gbps or 400MB/s. USB2.0 operates at 480Mbps half-duplex, or 60MB/s. USB3.0 can transfer large files (such as high-definition content) at speeds 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. Compatible with Windows 2000/2003/XP/Vista/WIN 7SP1, Linux, and iOS devices.
