I own a PS4 mainly for the exclusives. I already have 8 games installed, 4 installed from disc and 4 downloaded from PSN and have around 200GB of free space left. Only thing that's slowing me down from replacing the stock HDD is that I can't backup my PS4 games and that is not a good situation if I have 250GB capped internet service since I would have to redownload around 125GB worth of games. But then again the sooner I replace the drive, the less work it will be for me to reinstall my games. I'm considering the 1.5TB 5400 rpm HDD over the 1TB 7200 rpm HDD because of less heat.
