Best thing that ever happened to me as it relates to GTA VI:
A couple of years ago I was running close to having a full hard drive on my PS5. I went to GameStop to get a 1 TB internal hard drive. The guy to counter said:
"Look man, I'm not trying to be in your pockets, but do you have enough right now for an extra $125? If so, you might as well get the 4 TB hard drive. Trust me it's always better to have more space. You think that the 1 TB is enough, until it ain't.
"Get the 4 TB if you can afford it. Trust me. Not even trying to upsell you, cuz I did the same thing for my system."
So I got the 4 TB hard drive, and I'm glad I did because right now I only have 800 GB free. When it comes to memory, always get more than you think you'll need.
