Are we talking about MacOS or Windows?
There is a great utility that speeds copying in windows called TeraCopy from Code Sector that I always install on windows computers to manage and speed up file copying. It manages multiple copies, and cues additional copies serially. It also gives lots of information about what it is copying, how fast and how long it will take. Also has features you can turn on to do a compare after copy to ensure copy is accurate.

I believe queuing multiple copies is "faster" overall not because of raw performance, but because of human error. First, we are not the best judge of just how to optimize any given copy. Second, there will be time lost between the time one copy finishes and the time you queue up the next. This might be substantial if you are not paying attention. In my testing, Mac OS does a great job of negotiating multiple copies and does not appear to take a significant hit if you initiate several simultaneous transfers.
However, it is not first in, first out. It actually seems to make priority judgements based on file size and speed of individual transfers. If you have a major copy going and drop a small file on, the small file will copy quickly. If you drop too many on, the later ones will sit and wait. If you are on a major hurry for some files and not others, you might want to manually cue.

I'm racing to get files out onto an external usb transfer drive. The files are approx 75 GB in size. I started one and it est time at 44 minutes. Half way through it's transfer my second file was ready to copy. When I added it to copying it said 2 hour estimate of time. I figure that would drop down especially once the first file finished but it seemed like I'd be better off stopping the second file copy and restarting after the first file finishes. I figure bouncing between writing two files simultaneously for a single disk ext drive would take more time than transfering the files one after the other. Curious if this makes sense to anyone else.I figure if I had both files to begin with and dragged them both over to the external the transfer would have been handled in a sequential manner, but I don't know if that's how a copy actually is managed by the finder. Can anyone enlighten me on this subject?
