Great purchase. We quickly filled up the 1TB storage on our PS4 so this was almost a necessity. Really easy to install, just plug in and then format in the settings menu and it's ready instantly. The only drawback is it takes up one of the front usb slots we use to charge controllers (our console doesn't have one at the back). Have been using it for a couple of weeks with about 5 new games installed and we haven't noticed any impact on loading times whatsoever
