The PlayStation 4 comes with a 500GB hard drive, and let’s be real—that’s not gonna be enough space for some of you. The good news is that you can upgrade it.P
Check out this video by gamespot, which walks you through what you need to do to swap in a new hard drive into your PS4. Thankfully, it’s nothing too complicated.

So, it’s definitely worth considering.
