Well, we now have an answer to how long it will take to move:

One of them comes from GamesBeat's Jeff Grubb who tested how long it takes to transfer files between various drives. In the video embedded above, Grubb moves Assassin's Creed Origins (which is a 49GB file) around his storage locations in different configurations. Here's what the tests found.

Moving Origins from an external SSD to an internal SSD took only 2 minutes and 18 seconds.

2:18 min (138 seconds) to move or copy 49 GB ain't that impressive for NVME-SSDs, that's just 355 MB/s.

An external HDD-Raid ain't that much slower:
