What are you actually trying to do?
While there are multiple different kinds of 'RAID', it is probably not what you really want, aside from a buzzword.
combining 2 to have 1 big one
That's kind, of but not really, an 'answer'.
Why, is the question.
But....
1. You do NOT want to do that with a WD Green
2. RAID 0 is what you're looking for. But....
...that brings so many fail possibilities, it is soooo not worth trying to do this.
What is this PC used for?
There are so many ways to install things on different drives. Attempting to have them be a single drive letter is pretty much useless.
