    This is something I purchased for my PS5 Pro. I would recommend a good double sided heatsink with its use. Having an extra 4tb storage that is blindingly fast is fantastic.

    I use this ssd for storage and coding. This ssd is superfast to work with. Also, when rendering videos it processes much faster than the non-nvme ssd's. I am planning to purchase another one for dedicated gaming. I would recommend this NVMe.

    I got the 4TB version as a dedicated game drive and it is very fast. It has all the space I need for a very long time. It also has great TBW stats so this should last a long time.

    Perfect for PS5

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This works wonderfully with my PS5. Absolutely worth the steep price for the storage as anything under 4TB in my opinion is not going to suffice for gaming over the years. Obviously had to buy a 3rd party heatsink, but thats no issue. Absolutely recommend.

    Works exactly like it was supposed to. The only grip I have is the pricing. This SSD cost half the value of my ps5 and the drive was on sale. Smh

    No, I would not recommend this to a friend
