    Installed in my PS5, and it works great. Easily more space than most people could use with almost no storage management. Just remember to get a compatible heat sink along with it.

    I bought it at a discount when I caught up with the event. It is very cost-effective. It is used to upgrade my razer blade 14. The SSD speed is very fast, the capacity is large, and it is a good shopping experience.
