Part Number Differences

[Joel-LCMCD]

I am shopping for an M.2 SSD. One Newegg I find Sumsung 960 EVO with two part numbers, both are NVMe 1TB drives. Part numbers are MZ-V6E1TOB and MZ-V6E1TOBW. There is a $50.00 price difference. What difference does the "W" added to the part number make?

Could you please link both products directly?

Here are the links to the two drives:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820147595

https://www.newegg.com/Product/Product.aspx?Item=9SIA12K62A9505

Maybe I am looking too hard and the difference is obvious, but I can/t see it. I have a theory though. The second link mentions MLC in the description and I did not see that in the other. The first could be TLC, but it would be nice to know for sure before buying.
