Scammy model number tactics to avoid pricematching
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.bestbuy stocks a specific not truly recognized version of this drive to avoid pricematching with other retailers, despite the fact the drive is the same as the universal WDS400T2X0E and its shown here on bestbuy's product page under "from the manufacturer - documents - product sheet" they deny the price match request because of this made up model number they have. I'd advise to not get ripped off and just buy it somewhere else

Fast reliable storage fir yiu PS5 / PC
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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.

A Good Buy.
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Overkill for my game drive
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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
Posted .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.
