Hi:
I have this PC setup:
  • MB Asus Maximus X Hero.
  • CPU Core i7-8700K.
  • RAM 2x8gb Adata Spectrix D41 at 3200mhz.
  • Video Card MSI Gaming X Nvidia GTX 1060 6gb.
  • SSD M.2 Samsung 970 Evo Plus 250gb.
  • SSD M.2 Samsung 980 (non Pro) 1tb.
This is the problem:
Everything works perfectly fine, except for the M.2 Samsung 980 1tb, which does not work at the speed indicated by the manufacturer. It only and roughly works between 1100mb/s and 1400mb/s reading speeds. This happens even with it connected alone on the Board, and on both M.2 ports.

I've search about this but haven't have found any conclusive answer.
Do you have any idea what's happening here?

Thank you very much.

PS. Pardon my english.

Wow. Excuse me. I was mistaken.
After doing the Samsung Magician, and Crystal Disk Mark Tests, I saw that the results were correct.
I am used to doing the reading tests with the AIDA64 Disk Bench, and it gave me the low transfer rate results with the 980 (not so with the 970 Evo Plus) [see photo].
Forgive my mistake again. I must do more tests with other apps too next time.
Nevertheless:
What could make AIDA give me such poor results and Crystal and Magician not?

I attached links to photos of the tests:
