YouTube4TB PS4 Pro (NO LONGER NEEDED - SEE DESCRIPTION)
(THIS IS NO LONGER REQUIRED AS THE PS4 CAN NOW SAVE GAMES AND APPS TO USB HARD DRIVES)
In this video I show a method for using a 3.5 inch 4TB desktop hard drive with the PS4 Pro. It isn't perfect and there are some caveats but it does work.
The components I used are listed below (please note they are Amazon affiliate links:

The hard drive caddy I used was not purchased for the project but you should be able to find something similar very cheaply on Ebay. Just buy the cheapest one you can find that will do the job.
