Obviously this is a USB3.0 interface, why is your U disk transfer speed getting slower and slower?
I would like to share with you some knowledge about U disks with two different USB interfaces. We divide U disks into USB2.0 and USB3.0 interfaces according to transfer speed. USB2.0 refers to maximum transfer rate of interface: 480 Mbps. USB3.0 means maximum transfer rate of interface is: 5.0Gbps. In other words, for two USB sticks with same 64G, speed of USB3.0 is much faster than that of USB2.0, reaching an astonishing gap of more than 10 times.
Actually, there is a reason for low transfer rate of U disk 3.0. The culprit could be that there are too many things stored on your U disk, resulting in slow speed.
Here I will give an example to explain why too many files slow down U disk. I think everyone has seen water tank. The flow rate of water that we pour into water tank depends only on our pouring speed and has nothing to do with capacity of water tank. Even if water tank is ready to be filled, it can still be filled very quickly, but when water is full, it overflows. The U disk is different. The files we copy to U disk are stored randomly, and storage space of U disk is like a plate. The point where copied file goes is random. If storage point is file is deleted If file already exists, it will search for next storage point on its own until it finds an empty storage point. Looking around, I didn't find any free space, so transfer speed should be same as that of a snail. Therefore, too many files in U disk will slow down speed of file copying.
Now I will share two solutions
Method 1. U disk optimization
The operation method is as follows: First, right-click to open "This PC (My Computer, Computer, File Explorer)", and select "Properties". In properties window that opens, switch interface to performance column, and then click to select file system → removable disk, and then check "lazy write cache", and finally click OK to save settings. The U disk has been successfully optimized.
Method 2: Format U disk and restore factory settings
1. Open "Command Prompt" from "Start-Programs-Accessories" (or "Start-Run, type CMD and confirm")
2. Enter format b: /a:16k ("b:" here refers to your drive letter U), if U drive is in area F, it is "format F:/a:16k" and then press Enter.
Check U disk transfer speed after formatting is complete, you will be pleasantly surprised~~~
Note: The operation of second method is to format U disk, and before formatting, you need to back up important files in U disk to other places.
