Which SSD to put in Macbook Pro Retina 13 midl 2014 model A1502?

Question

Solid State Drives

I want to replace an existing 512GB SSD with some fresher and possibly faster speed through an adapter, unfortunately I didn’t find the original ones that fit on sale.

I read pretty good reviews about:

• Samsung 970 EVO Plus M.2 MZ-V7S1T0BW 1 TB
  
• A-Data XPG SX8200 Pro M.2 ASX8200PNP-1TT-C
  
• Samsung 980 PRO MZ-V8P1T0BW 1 TB
  

There is also the question of which adapter to choose, I found this option - https://kazan.partsdirect.ru/goods/667228

Also, who changed the disk, does it give any increase in total performance, it is obvious that in conjunction the processor - RAM - drive, the drive is the least speedy.
