Inside this box is a Seagate hard drive Samsung Spinpoint M9T 2TB (ST2000LM003 reference) The only current 2TB hard drive that is compatible with the PS4.
The PS4 now shows 1.77 after installing To 408 GB instead of 500 GB with PS4 new.
I put the old hard drive from the PS4 in the housing, making that premium I have a 500GB USB3 external drive.
