    Wow! Now this is speed and storage!!! I just enhanced my Gaming PC with this bad boy… effectively giving me 4TB on this SN850X and another 2TB on my WD SN850, equaling 6TB! Paired with my RTX4090 FE, and my 5800X3D, can you beat me now!?

    Definitely worth the money when on sale, but I wish it came with the small screw to lock it into place. Luckily my motherboard had a slot for it where it was under a heatsink that holds it in solidly.
