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, shielded by aluminum foil, which prevents interference), one group is used to send data, and the other group is used to receive data. This means USB 3.0 can perform read and write operations simultaneously at full speed. Previous USB versions do not support full-duplex data transmission. 2. Ultra-fast transfer speed. USB 3.0 is also known as SuperSpeed USB, which greatly improves bandwidth up to 5 Gbps full duplex or 625 MB/s, though the actual transfer rate is approximately 3.2 Gbps or 400 MB/s. USB 2.0 operates at 480 Mbps half-duplex, or 60 MB/s. USB 3.0 can transfer large files (such as high-definition content) at speeds 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 takes 43 seconds. Supports USB 3.0 (5 Gbps), backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) specifications. 4. Compatible with Windows 2000/2003/XP/Vista/Win 7 SP1, Linux, and iOS.
