Hello all, Can really use some help setting up raid, thanks

Hello,
I’ve been using Mac for almost 20 years and WD for about 15. But for whatever reason, I’ve never tried to set up a raid array. I recently came across 2 WD thunderbolt Duos (made specifically for raid).
I figured with all my years using Mac and WD I wouldn’t have a problem, but I can’t seem to get up and running. I was hoping someone here with some more experience could be so kind as to lend some help.
thank you
Joe
