    I bought this to add M.2 SSD storage to my PS5. It’s fast and it gets the job done. I added my own Heatsink which is a must. I’ve had no issues.

    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!

    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.

    Great performant internal drive for fast file transfers/installs and space for large applications and assets. Remember to set it up and format it like other drives (search online).

    Chose to buy this storage because it was way cheaper than the one with the heatsink. Bought the heatsink separate, easily installed it and have had no problems with it. I’m pleased and saved a couple of bucks!

    Amazing speed! I had another m.2 drive Generation 3, and setting my computer to take advantage of the full speed of a Gen4 was almost double the speed as before... Make sure you use the right settings and hardware to take advantage of Generation 4

    After purchasing 4 of these drives over the past year or so, I can confidently state its performance is top notch and that, so far, reliability has not been an issue. Great value for the money, just try to catch it when it's on sale.
