Your PlayStation 4 console comes with a 500GB hard drive, but that is not enough for video games on the the PS4. Most Windows laptops come with a terabyte or more now, and you can't help but feel shortchanged by just 500GB considering that most games take up around 50GB of space each. This handy guide shows you how to replace the 500GB hard drive that comes with your PS4 for something a little more substantial. And no, doing this will not void your warranty; Sony says so in the manual that comes with your console.
You could use a solid state drive (SSD) or a hybrid drive but we recommend sticking to a standard 5,400rpm laptop drive as others are not officially supported by Sony. Once you have your drive, you're good to begin.
First, follow the instructions on how to back up your PS4 games and data.
Once the data has been backed up, turn off the PS4 and unplug it from its power source.
You'll notice a PlayStation branded screw (pictured below), remove it with a screw driver.
Pull the HDD toward the front of the system to remove it.
Using a phillips screwdriver, remove the screws (four places).
Do not remove the rubber inserts from the screw holes.
Place the replacement hard drive on the mounting bracket, and then attach using the screws (four places). Be careful not to make them too tight.
Attach the hard drive to the system using the screws, ensuring it is fully inserted in the hard drive bay.
Reinstall your PS4's system software (instructions are here).
Now you can copy the data you backed up earlier via pen drive to the PS4 after switching it on. Keep in mind that you must be signed in with the same PSN account used when you first copied the saved data:
You're good to get back to gaming on your PS4. Now with more storage space.
