What is a high speed u disk?

We know that the U disk technology through the USB 1.0, USB 2.0, USB 3.0 of the standard stages, USB 1.0 u disk is now generally eliminated. First from the USB 2.0 standard, the USB 2.0 interface standard three speed specifications are:

High-speed 25mbps~400mbps (Max 480Mbps) (High speed)

Full-speed 500kbps~10mbps (Max 12Mbps) (Full speed)

Low-speed 10kbps~100kbps (Max 1.5Mbps) (Low Speed)

This shows that the USB 2.0 high speed U disk maximum speed of 480Mbps, which in our daily use is acceptable. But this is only theoretical speed, it is not possible to achieve such transmission speed in actual use. Moreover, with the transmission of operating system mirroring, High-definition audio and video files, such as the increase in demand, the speed of the USB 2.0 standard gradually appears backward, the use of USB 3.0 standard High speed U disk has been launched.

According to the public data, the maximum transmission bandwidth of USB3.0 is up to 5.0Gbps (i.e. 640mb/s), which is 10 times times more than the USB 2.0 standard transmission speed. Of course, this is also theoretical speed, but the actual speed is much faster than USB 2.0. Therefore, today's high-speed u disk, you must be the use of USB 3.0 standard U disk.
