Just as the title says, what model do you have? At the minute I've got an original 500gb Phat PS4 from when it first released in 2013, but soon i' upgrading to the God of War Limited Edition Pro PS4 which comes with a 1TB HDD, definitely better than the standard 500gb. Let me know what yours is below and also what is your favorite model of the PS4, Poll will be above
