That's an improvement on the original fat PS3 that I well after its prime (2014 or so?). The screws on the original HDD caddy were in so tight that even with the correct driver and OK technique I managed to strip them. In the end I threw the caddy out and made some shims out of cardboard to stop my replacement SSD bouncing around too much, it worked great for a few years until it succumbed to the YLOD. My original fatty PS2 still works great!
