I think that beyond 1, max 2 tb is just a waste to have more storage, you’ll just end up stuck with the " Netflix dilemma" all the time. Every game is already in your Steam library (or the other ones) as it is. Even if the wifi download take time, with a cheap dock and a cable connected to the modem you can download all your title quite quickly. With 2 tb there should be also enough room for “free version game” files.
