I noticed that the image is downloaded / copied faster than the unpacked one, although the volume is the same. What is it connected with?

Because one large file takes up one entry in the MFT, while many small files take up many entries.

Image of what? Download from where?
I can assume that we are talking about an ISO image, then the fact is that .iso is one file, and when unpacked it is a lot of files and a lot of file operations.
