Factors that affect file transfer speed:
1. The transmission speed of mechanical hard disk is limited to about 135MB/S.
2. Most USB drives on the market claiming to be USB 3.0 have an actual transfer speed of about 120MB/S.
3. The transfer speed of USB2.0 interface is limited to about 38MB/S.
4. Fragmented file transfer will significantly reduce the speed.

Therefore, in order to achieve the ideal transmission speed, the conditions should be:
1. The sending and receiving devices should be solid state hard disks, real USB3.0 flash drives, etc.
2. The size of each file to be transferred should not be less than 250M.
