Opened PS4, HDD out, HDD pure, ready.
Before NEN USB stick prepared, PS4 in the emergency mode (or whatever his name is) booted, HDD formartiert and voila goes. :)
The board is in the PS4 inaudible to me and the loading times ..... are about the same as before, where there is also a SSD nix to changes according to various tests. The 2TB were immediately recognized (almost 1,8TB available), all of therefore great.
