    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

    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!

    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.

    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).

    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!

    High capacity, high speeds, high quality! Overall a solid choice for a solo boot drive/mass storage drive. Or as a secondary, tertiary or even redundant drive if you have the money and desire lol. Can’t go wrong with the WD brand too!

    I bought two 4TB WD SN850x and these are very fast NVMe drives! They have great random read and write speeds and do not run hot on my motherboard. They average around 42c temps.
