PlayStation 4 faster with a Database Rebuild, SO your PlayStation 4 is running a bit slow, or a game crashes for no reason, it probably time to rebuild the Database, like any Computer the hard drives need a rebuild once in a while. follow the instructions below on how to do it.
DO NOT HIT THE INITIALIZE PS4 – THIS WILL WIPE EVERYTHING
How to rebuild your database
1, Power off your PlayStation 4 and do not use rest mode.
2, Hold the power button down until you hear two quick beeps. This will alert you that you have entered Safe Mode.
3, Connect your DualShock 4 controller to your USB-A slot in the front of the PlayStation 4.
4, Scroll down in the menu until you reach option 5, Rebuild Database.
5, Press the X button to start the rebuild.
This process may take some time, depending on how many games you have on the drive and how full it is. What the rebuilding does is essential reorganise the hard drive into a better order so your system can find things quicker and easier
Database rebuilding is a fairly simple task that should be done every few months — doing it once a quarter is best — and the more frequently you do it, the less time the process should take.
Whats the Risk
Database rebuilding sounds like cleaning the drive and cleaning sounds like deleting stuff — but the truth is that database rebuilding shouldn’t actually delete any data unless a file is corrupted. Corrupted files get deleted, but if you get corrupt stuff these are better to be gone anyway. While I cannot guarantee that database rebuilding is 100% without its risks, it shouldn’t delete anything, and it happens in Safe Mode.
