After reading several reviews online as well as elsewhere, I decided to upgrade my HD (to a 3TB HD) on my PS4 using this. A few commented that there were no problems going beyond the 2TB limit recommended on the product. While the expanded storage was a bonus, the loss of using rest mode was discouraging as I did not want to leave my unit on all the time. The few times it did go to rest mode, it would shut down. I ended up getting rid of this and just buying a 2TB HD made for laptops. Fits perfectly inside the PS4 and works perfectly. So if you are wanting to keep all the features of your PS4 but still get more storage, then just buy a 2 TB HD. If rest mode is NOT important to you and you jsut want make storage, then this may be the product for you. Good luck.
