What is the general reading and writing speed of U disk 3.0?

The reading speed of U disk 3.0 is generally "20M/S-90M/S", while the writing speed is generally "15M/S-80M/S". The writing speed of a U disk equipped with USB3.0 can reach up to "640MB/s"; as the time of the U disk increases, the writing speed of U disk 3 will gradually slow down, and may eventually stabilize at around "60M/s".

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

According to scientific experimental tests, the writing speed of U disk equipped with USB3.0 can reach up to 640MB/s. The writing speed of U disk under the USB3.0 interface is generally 15-80M/S, and the reading speed is generally 20-90M/S

Since there are four different USB3.0 interfaces on the market, and each The transmission speeds of the interfaces vary. Therefore, it cannot be considered that the reading and writing speed of U disks with USB3.0 protocol is the same, and it needs to be judged based on the material of the U disk.

In addition, as the U disk time increases, the writing speed of U disk 3 will gradually slow down. For example: the writing speed of a U disk just shipped from the factory is 600M/s. During the process of connecting to read and write files, the transmission speed of the U disk will gradually decrease, and may eventually stabilize at around 60M/s.

Extended information:

USB3.0 introduces full-duplex data transmission. Two of the five lines are used to send data, the other two are used to receive data, and one is a ground wire. In other words, USB 3.0 can perform read and write operations simultaneously and at full speed.

The new USB 3.0, while maintaining compatibility with USB 2.0, greatly improves bandwidth while also achieving better power management. Due to the use of the new protocol, USB3.0 devices can be recognized by the host faster and can also have better file processing efficiency.
