    I had a 2TB WD Black and needed more space, so I upgraded to the 4TB drive in my laptop as the second drive. I have had no problem with it.

    The read and write speeds on this are ridiculous, transferring bug files? Downloading huge games and hate waiting? Buy it!

    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!?
