What speed does USB 3.0 support?

USB 3.0 supports a maximum data transfer speed of 5 Gb/s (Gigabits per second). This increased speed represents a significant improvement over its predecessor, USB 2.0, which has a maximum speed of 480 Mb/s (Megabits per second). The advancement in speed for USB 3.0 allows for faster data transfer rates, making it particularly beneficial for applications that require quick data access and transfer, such as high-definition video streaming and large file transfers.

This enhanced speed is one of the key selling points of USB 3.0, as it improves efficiency and reduces the time needed to transfer large files.

While other speeds listed in the choices pertain to different USB specifications—the 480 Mb/s is specific to USB 2.0, and 1.5 Mb/s is the speed of USB 1.0—USB 3.0's distinct capability is evidenced by its 5 Gb/s performance. The option noting 10 Gb/s relates to USB 3.1, which is a subsequent iteration that allows for even faster data transfers. Thus, the identification of USB 3.0's speed as 5 Gb/s is accurate and underscores its significance in the evolution of USB technology
