Features: 1. Full-duplex data transfer. 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, with aluminum foil shielding around the periphery, preventing interference). One group is used for sending data, and the other for receiving data, allowing USB 3.0 to perform read and write operations simultaneously at full speed. Previous USB versions did not support full-duplex data transfer. 2. Ultra-fast transfer speed. USB 3.0 is also known as SuperSpeed USB, significantly increasing 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 multiple files (such as high-definition movies) 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.
