Usage Tips: 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 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 read and write operations at full speed simultaneously. Previous USB versions do not support full-duplex data transmission. 2. Ultra-fast transfer speed. USB 3.0 is also considered SuperSpeed USB, which greatly improves bandwidth, up to 5 Gbps full duplex or 625 MB/s, though the actual transfer rate is about 3.2 Gbps or 400 MB/s. USB 2.0 is 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), compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) specifications. 4. Supports Windows 2000/2003/XP/Vista/WIN 7 SP1, Linux, and iOS.
