The SAMSUNG M9T 2TB HDD 5400rpm SATA 6.4 cm 2,5Zoll was purchased to replace the 500GB drive to the PS4. The preparation of the PS4 and the replacement of the hard drive is completely problem-free. On the Sony website there is a corresponding short instructions on how to back up its user and game data from the old disk quickly and easily and the new drive makes the system available. The Samsung works fine since the exchange and I can state in terms of speed no difference to the old plate.
