False advertising
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Only had like 3.6 TB on it. I know you dont get a full 4tb regardless of what brand you go with, but seriously, why advertise it as a 4tb drive if is missing almost 500gb of storage?

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

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.
