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 to prevent interference), one group for sending data and the other for receiving data. This allows 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, which significantly increases bandwidth up to 5 Gbps full-duplex or 625 MB/s, though actual transfer rates are typically around 3.2 Gbps or 400 MB/s. In comparison, USB 2.0 operates at 480 Mbps half-duplex, or 60 MB/s. USB 3.0 can transfer large files such as high-definition movies at speeds limited only by the storage device. 3. For example, a USB 3.0 flash drive can transfer 1 GB of data to a host in approximately 15 seconds, while USB 2.0 takes about 43 seconds. Supports USB 3.0 (5 Gbps) and is backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps). 4. Compatible with Windows 2000/2003/XP/Vista/Windows 7 SP1, Linux, and iOS.
