What is the transfer speed of USB 2.0?

The transfer speed of USB 2.0 is indeed 480 Mb/s (megabits per second). This specification was introduced to significantly improve data transfer rates compared to its predecessor, USB 1.1, which had a maximum speed of 12 Mb/s.

USB 2.0 was designed to support a wide range of devices, including digital cameras, external hard drives, and more, making its speed an important factor in user experience. The 480 Mb/s rate enables fast data exchange, which is essential for transferring large files or accessing high-bandwidth devices.

In contrast, the other speeds listed are associated with different versions of USB. For example, USB 3.0 and later versions offer much higher transfer rates, such as 5 Gb/s and 10 Gb/s, which reflect advancements in technology that allow for faster data transmission. The 1 Gb/s figure is not a standard speed for any USB version, as it is lower than USB 2.0’s capabilities. Understanding the transfer speeds of different USB versions is crucial for selecting the right connections for various devices and applications.
