Packing thousands of files into an archvie using 7-zip "Store" compression. Does this significantly speed up a file transfer?

Question

I have a folder with 40,000 jpg images, and I'm assuming that if I pack them into a 7zip file using the "Store" compression level it would make file transfers a lot faster since the the 40k files would be recognized as one file? Correct me if I'm wrong. Thanks!
