What is 2 0 3 0 about USB flash drive? How normal are the read and write speeds?

.0 refers to the speed of data transmission, the fastest, good point of read and write are either stable at about 15000kb s or read more than 2000kb s, in addition, you can tell you a U disk acceleration method:

1. Open "My Computer".

2. Right-click on your USB flash drive icon and click "Properties".

3. Switch to the "Hardware" tab.

4. Choose your USB flash drive (generally speaking, the first one is your optical drive, the second is a USB flash drive, and the third one is a computer hard disk, anyway, choose according to the brand of your USB flash drive).

5. Click Properties

6. In the pop-up window, switch to the "Policy" tab (there is no "Policy" tab after clicking the property in the 5th cloth in Win7, in the "General" tab in the pop-up window, click "Change Settings", and then select the "Policy" tab in the pop-up window).

7. Select "Optimize for Better Performance" ("Better Performance" in Win 7) 8. OK.

The maximum theoretical speed is 480Mbps = 60Mbps S, and the transmission bandwidth is 10 times this value, due to the transmission medium material and internal loss, but the attenuation of the transmission signal is inevitable, so it is difficult to achieve in practice, and it is also related to the computer.

My read 10m, write 30mThis is a mouth.

Theoretically, it can reach a speed of 480mbps seconds, that is, 60m s. However, the specific speed is related to the U disk memory chip, main control chip, and motherboard chip. Even if it is the same USB flash drive, the speed is not the same on different computers.

Also, the more fragmented the copied file, the slower it will be. You can copy large files, such as a few gigabytes of movies. Try it on other computers at the same time.

Mine is around 5m, but even if it doesn't reach this speed, it doesn't mean it's a fake.

Extended Material: and Differences:

Theoretically, the transfer rate is 480Mbps, which is 60Mb S, while the transfer rate is 625Mb S. So, it's faster than passing the door.

In appearance, the middle plastic sheet is blue, while the middle plastic sheet is black or white.

On the pins, the male has 9 pins and 5 pins. In order to be compatible with the version, a 9-pin design is adopted, four of which are exactly the same shape and definition, while the other five are prepared for the morning door.

The above is all the relevant extended information on the subject, hopefully.

According to the scientific test, the write speed of the USB flash drive can reach up to 640MB s.

There are four different interfaces on the market, and each interface has a different transmission speed. Therefore, it cannot be considered that the read and write speed of the USB flash drive with the protocol is the same, and it needs to be judged according to the material of the USB flash drive.

In addition, as the time of the USB flash drive increases, the write speed of the USB flash drive 3 will gradually slow down. For example, if the write speed of a USB flash drive that has just left the factory is 600 ms, the transfer speed of the USB flash drive will gradually decrease during the connection to read and write files, and may eventually stabilize at about 60 ms.
