The maximum data transfer speed of USB 2.0 is 480 Mbps, which is significantly faster than its predecessor, USB 1.1, which had a maximum speed of 12 Mbps. This enhancement in transfer speed allowed devices such as external hard drives, printers, and cameras to transfer data more efficiently, thus making USB 2.0 a widely adopted standard during its time. It is important to note that while USB 2.0's maximum speed can reach up to 480 Mbps under optimal conditions, real-world performance may vary based on factors like cable quality, device compatibility, and other environmental conditions. Understanding these specifications is essential for selecting the right USB technology for various applications.
