Problems solved by technology

The PCI data interface has a high transmission rate but is not easy to use, while the USB2.0 data interface is limited to a bandwidth of 480Mbps. In recent years, the USB3.0 (Universal Serial Bus3. The data interface of the bus) is widely used due to its hot-swappable characteristics, fast transmission speed, and stable performance. Its ease of use and high data throughput rate can be described as the best solution to the above two contradictions. Substitutes" will surely have a better development prospect in the future market
