    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.

    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.

    Bought this SSD to replace a 2TB one (same WD Black, just smaller). No heat issues, stability is rock solid, and it works great in my gaming laptop. Cloning it was easy - I recommend getting an external USB enclosure for that. I've had great success with using WD SSDs for many years now, and still recommend! Great value for the money!
