Or if you don’t want to deal with upgrading it, you could just transfer some games, saves, etc. to an external hard drive before deleting them. It still wouldn’t be as nice as actually having a bigger hard drive for the PS4 itself, but it would be better than deleting them permanently.

Did they already sell out or something? The link doesn’t work, and the only other controllers like that that I can find cost over $200 on Amazon.
