I bought the 2TB version and it does work with the PS4 (current version 4.50). At first it said it didn't support it but after I restarted my PS4 it worked. Currently works as intended. There's 1.84TB usable after formatting. It took 19 minutes to transfer 3 games (118.3 GB) over from the internal hard drive to this external hard drive. Will update if anything arises.
Edit: It had been a little over two months and its still working as intended. To answer a common question:
It works out of the box. Literally just plug it into your ps4 go to devices under settings then USB storage devices. It should pop up under there, select it then it will say "Format as extended storage" and select that. The support for external hard drives is absolutely great. If you have a TON of downloadable games then you can simply just have multiple external hard drives and download all you games to them. Then you can just plug in the external hard drive with the game you want and you're good to go. I highly recommend looking up how to set it up if you are still having trouble. It is very easy.
Edit (July 5 2019): Still working as expected.
