Upgrading the PS4 hard disk
We’ve got to shuffle some disks around, so in the process I bought an upgraded hard disk for our PS4 as space on there is getting a bit tight. We opted for a Seagate Barracuda ST2000LM015 - a 2TB drive. Not sure if the 5400RPM will be a concern with loading times or not, but I don’t think it’s slower than the stock one.
Replacing it is fairly trivial, and not entirely unlike upgrading the hard disk in a PS3:
Prepare a FAT32-formatted USB with the current PS4 update on it.
Power off the PS4. Not rest mode, go to the power menu, and choose “shut down the PS4”. Probably doesn’t matter if you’re upgrading the hard disk, but better safe than sorry. Unplug the power cord and any other cords that might get in the way.
Slide the shorter side of the top cover straight off to the left. It’s simultaneously harder and easier than you think it will be, but trust me it doesn’t need any tools and it’ll come right off with your fingers and a bit of “oomph”.
There’s a single phillips screw on the left that holds the drive caddy in place, undo it and the drive caddy should slide straight out.
Undo the four screws holding the drive in the caddy, and replace the new drive into it.
Slide the drive back in and replace the last screw.
Put the USB stick in the USB socket and power on the PS4, then follow the prompts to initialize the new drive.
I regret that I did not take pictures of it apart. :(
