Why does it take longer to copy files from the computer to a USB flash drive?

This is not necessarily, when copying for a period of time, your file may be small or the computer is running fast and other reasons cause the display time to be short, but later because of the file or computer speed and other reasons cause the speed to be slow, but this speed is based on the current speed divided by the file size, is the instant speed does not represent the real time you copy the file.

That's straightforward, hope

Maybe you have a bit of a problem with the USB flash drive, you can try to reformat it. If it doesn't work, it may be damaged on the USB flash drive.

It's very simple, if you copy something very big at once, that's it, you can copy it separately, so it will, quickly, understand, heh!!

It depends on the size of the file you copy. Sometimes it's counting copy time.

Same as the second floor! Just be the reason for your card! See how fast it is! class, the higher the number, the faster, and vice versa!

Windows systems have cache settings for each drive. The larger the setting, the longer the previous copy will be faster, and the larger the size of the copy. When the information in the cache is written, it is the normal write speed of the USB flash drive.

The file is very small, and the copy speed is very fast, and the file is very large, and it feels that the speed is getting slower and slower. Generally, it can reach 10-20m seconds at the beginning, and about 4-7m after stabilization. Good brands will be a little faster, but not a lot.

But the worse brands are not good. Don't just look at or, there are still gaps between different brands.

The USB flash drive has a read speed. There is a write speed.

The read speed is faster than the write speed. Therefore, when the USB flash drive is copied to the computer, it only reads the data in the USB flash drive. So fast.

When copying data from a computer to a USB flash drive, you need to write to the USB flash drive.

So it's slow. Time-consuming.

Normal. Don't worry about it.

In addition, due to the way the USB flash drive writes operations, a lot of time is spent on creating files in the USB flash drive. So the more files are written. The slower.

The solution is to compress a large number of files, and select the "storage" mode when compressing, which is only equivalent to merging multiple files into one file, and does not compress the data. So the compression time is also fast.

When you copy this file to a USB flash drive, only one file is created on the USB flash drive, and then data is written.

That's a lot faster.

1. First of all, we need to see what the file system of the U disk is, open the computer - removable disk - right-click on the properties.

2. At present, most USB flash drives use FAT32 format, which is also the reason why most of the transmission speeds are relatively slow.

3. If the file system is FAT32, you need to make some optimizations, you need to change the U disk format to NTFS format, you can use the advanced formatting technology that comes with win7. Convert the file system of the USB flash drive to NTFS, and then align it to 4K by the way, by right-clicking on the removable disk - Format - File System NTFS - Allocate unit size 4096 bytes, click Start and wait for it to be formatted.

4. After completing the U disk format conversion, the copying speed will be faster.

It depends on the read and write speed of the USB flash drive, and the write speed of the USB flash drive for normal transmission is about 5-7M, and the general one is about 2M! It depends on the quality of the USB flash drive! To identify the quality of the USB flash drive, you can search a lot upwards, and now many vendors are selling fake USB flash drives, and the read and write speed is quite slow.

This depends on the size of the thing which I copied......
