Even the latest PS4 Pro model comes with an HDD. I can’t remember when was last laptop shipped with HDD but I can imagine what an SSD upgrade brings to an old PS4.
The only issue is, if I put the new SSD drive in straight away I’ll need to install the PS4 OS and then download everything. Now it’s a good opportunity to show off my Linux skills, is it not?
I plug in the old PS4 HDD and the new SSD to my workstation which runs Ubuntu Linux, then only 1 command is needed to do the disk copy:
dd if=/dev/sdd of=/dev/sdc bs=1M status=progress
This took me about 2.5 hours to finish, but before you start, make sure /dev/sdd is the old drive and /dev/sdc is the new drive in your setup because this is very destructive if /dev/sdc is the old drive by any chance.
Then I put the SSD into the PS4 and it booted up with all my games, except being much faster!
