This one goes without saying. Veeam’s Fast SCP is another file copy tool, but designed specifically to SCP or securely copy files, and do it very fast.
Consider pulling this down and giving it a shot the next time you are going to spend most of an evening or two copying a few TB of VM files about. You will love every second it saves you. Veeam’s Fast SCP can be downloaded from here.
