How long is a piece of string?

Plug it in. It will tell you how long it's going to take.

lol sorry just not done it before was just after a rough guess is the thunderbolt port the same as fire wire 800 I'm having trouble finding out for sure.

It's not the same.

It depends how much data you have on your computer. It'll take a lot longer the first time, obviously. But time doesn't really matter, it doesn't interfere with anything. Just let it crack on in the background.
