What transfer speed does USB 3.0 support?

USB 3.0, also known as SuperSpeed USB, supports a maximum transfer speed of 5 Gb/s (gigabits per second). This significant increase in speed compared to previous versions, such as USB 2.0, denotes a major advancement in data transfer technology, allowing for faster file transfers and improved performance for devices that require high bandwidth, such as external hard drives and high-definition video peripherals.

To provide some context, USB 2.0 supports a maximum speed of 480 Mb/s (megabits per second), which is much lower than the speed of USB 3.0. The later versions such as USB 3.1 and USB 3.2 further increased the transfer speeds to 10 Gb/s and 20 Gb/s respectively, highlighting the evolution of USB technology, but USB 3.0 itself is specifically rated at 5 Gb/s.
