No matter what solution you choose, since you're replacing your drive outright, you will lose any of the data stored on the (old) hard drive itself.

Here are some of 2018's best external Hard Drive options for the PS4 and PS4 Pro: There is now a large amount of options to expand your PS4 Storage. With the addition of external HDD support, you can now use any USB 3.0 HDD with a minimum of 250 GB and a max of 8TB. The DataBank enables the use of physically larger drives that wouldn't otherwise fit into the PS4 drive bay. Note that there is also a third-party drive upgrade solution on the horizon custom-made for the PS4 by Nyko, called the Nyko DataBank, but we have yet to test it. So the better path remains swapping out the internal drive entirely - and it's easy to do. If you want to use a hard drive you already own that doesn't conform to the PS4 size restrictions, you can of course connect it via a SATA cable instead of the built-in hard drive, but that would mean leaving the top of your PS4 open. There you can select App Install Location and choose the 'extended storage' device. To change the install location to a external hard drive or USB storage, go to Settings > Storage and hit the Options button. You can play games off your external storage, but be sure the connection isn't interrupted while you're playing.

Note: The PlayStation 4 supports the connection of external hard drives or USB storage devices.

A newer SATA III (SATA/600 or faster) drive will work fine in the PS4, but you won't get the speed benefit as it'll operate at SATA II speeds.

Note that SATA II is sometimes called SATA/300 or SATA 3.0 GBps. You can also upgrade to a faster 7200 RPM SATA II hard drive. Replacing your hard drive with a compatible device does not void your PS4's warranty. Given that HDD prices have come down significantly, you should definitely consider a drive that gives you plenty of space, such as a 2TB version.

You can replace either hard drive with any hard drive that complies with these standards, is no thicker than 9.5mm, and is larger than 160GB. The standard PS4 hard drive is a 500GB 5400 RPM SATA II hard dri, whereas the PS4 Pro includes a 1TB drive.
