I can add 3 more m.2 SSD-s if I wanted.
The main reason is to just have a bigger space for the Windows and non-game programs.
The 970 PRO would stay with me as a scratch drive, since it still quite fast, and actually beats the 980 and 990 PRO SSD-s in average speed
As I mentioned, the 2TB Kingston Fury gives almost 700GB of SLC, and currently my system could live only in that, and costs about the same as the 990 PRO
Wish TPU had tested SN850X, but the specs and price looks right.
Sometimes when I have many many layers in PS.
If WD, then I would choose the SN850X, also nice SLC buffer
Good point, and I am still thinking heavily how could I manage my things, the drive is on 95% TBW, so still have years in it.

I noticed how good the Lexar SSDs are
Would buy a 4TB KC3000 or one of these Lexar drives for fast media storage 4K60 or 8K-RAW footages.
But that is for next year.
