    This was a great addition to my PS5! These games take up so much space that this is the perfect solution. 4tb with super fast loading times has been a game changer.

    Very nice. It freed up my first SSD, so I downloaded all my videos and pictures and files on this SSD. It holds a ton and definitely worth it.

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

    I got on a sale and at that time it was a great value for storage you get. Personally, this company has always been fast with its hard drives.

    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!?

    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.
