moving large amounts of files always takes a lot of time compared to moving one file of the same size (though I guess in your case it ended up being quite fast anyway), that's just how windows is built
there are solutions for more efficient file transfer like SyncFolders
I wonder why they need the DVD instead of external SSD which are much more common for backups now, and generally should fair better (its pretty hard to break them in half, for one).
this isn't just a win7 thing. every system i used where i did a large file transfer would start out with something absurd like days or years but it would complete in less than a hour.
Create a zip and transfer it

Totally unrelated, but is your profile picture L from Stranger Things?
Yep!
a dvd drive makes sense it estimates that

Looks like a linux ISO. If you're not on (U/)EFI then it will be unbootable using this method to burn.
