Features: 1. Full-duplex data transmission. USB 3.0 includes additional signal lines compared to earlier versions, enabling simultaneous data sending and receiving, allowing for concurrent high-speed read and write operations. Previous USB versions did not support full-duplex transmission. 2. High-speed transfer performance. USB 3.0, also known as SuperSpeed USB, offers a maximum theoretical bandwidth of 5 Gbps full-duplex (625 MB/s), with typical real-world transfer speeds around 3.2 Gbps (400 MB/s). In comparison, USB 2.0 supports up to 480 Mbps half-duplex (60 MB/s). USB 3.0 enables fast transfer of large files such as high-definition videos, limited mainly by the connected storage device's performance. 3. A USB 3.0 flash drive can transfer 1 GB of data in approximately 15 seconds, while USB 2.0 requires 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/Win 7 SP1, Linux, and iOS systems.
