Yeah I think that was the case before as well, you're talking about that Nyko adapter to put 3.5" drives in the ps4?
IMHO, anything over 2TB is an overkill because you'll never be playing ALL of your games on that drive, let's say every game is ~30Gb, you'll never play more than 60 games simultaneously, you can always delete stuff to clear your space.
