    I bought this right after I purchased my PS5 and so far all the games load up right away and I haven’t noticed any lag. Also, with so much space I won’t have to worry about storage for years. The only things I don’t like is the price and lack of heat sink.

    I upgraded my games drive from a traditional hard drive to this drive and it's lightyears faster than my old spinning rust. I used to have enough time to get up and go get a drink my my games were loading and it's down to seconds.
