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. That is to say, 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 as SuperSpeed USB, which greatly improves the bandwidth, up to 5 Gbps full duplex or 625 MB/s. However, the actual transfer rate is about 3.2 Gbps or 400 MB/s. USB 2.0 is 480 Mbps half-duplex, that is, 60 MB/s. USB 3.0 can transfer a large number of files (such as high-definition videos) at the storage rate 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. Not compatible with iOS devices.
