If it doesn't drop 20% of its reported health on casual usage in the first year it is a better product than my real 980 pro.
Hmmmm. I have three Samsungs at this time and have sold a couple, including the first gen 950 Pro (that was a couple years ago, and I got $100 for it, at 500 gb! ) Now, new 1 tb 980 Pro's can be had for about $100 or even less...
My 500 gb 970 Evo has been in a PC as its OS drive for almost 4 years and is at 97%.
My 980 Pro 1tb is in 2 PC and is at 99% I bought it from on either FB Mkt place or Offer Up.
I bought two 2 tb 980 Pro's from a craigslist seller for $500 a couple years ago. Sold one the next day for $300!
All test out at the speeds they should. They are not counterfeit and surely haven't lost 20% of their life (health) or any performance.
I have several other NVMe drives, Corsair MP600, addlink, and Adata S8200 Pro- two of them...both were bought before the parts switching mess was reported. All but one still perform at advertised speeds. The addlink has slowed, but that could be due to some overall performance drops that the laptop it is in has been exhibiting, of late.
And I have one of the fastest and top rated drives, a 2 tb WD SN850X, that I bought on ebay, ready to go in a new build. I expect it will also prove to legit.
