Computer display is slow when USB disk is inserted

Slow computer display when plugging in a USB flash drive is a problem that many people often encounter when using a USB flash drive. When we inserted the USB flash drive, we found that the computer displayed a very slow reading speed and could not even be used normally. How should we solve this situation? Here, PHP editor Strawberry has summarized some common solutions for everyone, hoping to be helpful to everyone.

There are many types of U disks on the market. In addition to the basic capacity, the transmission speed is also very important.

But hey, many people's USB 3.0 U disks are inexplicably "downgraded" to USB 2.0 when they are used, and the speed is greatly reduced.

It is necessary to talk about the difference between USB 3.0 and USB 2.0.

Give me a set of data directly so that you can understand more intuitively.

It can be seen that the speed difference between USB 3.0 and USB 2.0 is still quite large. The theoretical speed is only 60 MB/s. , one is going to 640MB/s.

In terms of color, USB 2.0 is generally black, while USB 3.0 is mainly blue.

But oh, pay attention to the stitches inside.

Both models have 4 pins on the front, but the difference is that USB 3.0 has 5 pins on the back.

The first 4 pins are USB 2.0 signal detection, and the last 5 pins are USB 3.0 signal detection.

So, a very interesting thing will happen at this time.

If you insert the U disk too slowly, the computer will capture the USB 2.0 signal first, but will not receive the subsequent USB 3.0 signal. Therefore, USB 3.0 devices will be recognized as USB 2.0.

Simply put, your hand speed is too slow.

To this end, I also did an experiment.

Deliberately slow down the speed and insert the USB flash drive, deliberately letting the computer recognize it as a 2.0 USB flash drive, and then transfer the file to test.

The speed is like this, a video of about 6G takes about 11 minutes.

The same U disk, the same USB socket, this time quickly insert the U disk.

The same file, the speed is obviously much faster, and the time is expected to only take about 3 minutes.

So, when using USB 3.0 devices, especially U disks, remember to move faster~
