Can I upgrade my PS4 drive?

Yes! And it’s easy, so long as you get the right drive: a 2.5-inch SATA that is no more than 9.5mm tall. Back up your data to a USB key via Settings/Application saved data/Saved data in system storage. You won’t be able to back up game installs, just saves.

Unplug your PS4, then slide off the top cover and remove the hard drive with a Philips screwdriver, replacing it with your new one. Download the PS4 system software, plonk it on a USB key in a folder called Update, inside a further folder called PS4, and plug it in to your console. Power up, holding down the power button until instructions appear on screen. Follow them carefully.
