Samsung 256GB SSD PCIe/NVMe M.2 80mm

PM961 MZ-VLW256HEHP.

Brand new.  Pulled from new Lenovo 910 series desktop.  Never used.  No retail packaging.  Card Only.

Manufactured April 2018

I see listings here on eBay referring to these as OEM versions of the 960 Pro version.  I am not sure but this seems to be debatable.  They might be comparable to the 960 EVO non-Pro.

"They are not the exact same drive. The 960 pro has a native turbowrite function to boost writes from what I read. 
The sm961 is actually faster in some scenarios (between the pro & evo)"  

"PM961 = Evo 960 or similar SM961 - Pro 960 or similar."
