You have to put in the correct type of SSD. The cheapest are TLC (triple layer chip) which are good for laptops, they last about 3k-5k write cycles. The MLC (multi layer chip) is a bit more expensive but is good for gaming. They last 8k-10k write cycles. About enough times to install gta5 about 16k times. The most expensive is SLC but that’s for industrial use.
I have a 1tb SSD and it does make a difference with load times. About 30 seconds faster and no lagging during game play.
