Windows 10: Why is C Drive not drive "0"

My primary drive is a Samsung M970 Pro M.2, Drive C, my secondary drive is a Samsung M860, drive D, and I have a CD drive which is drive E. My question is: Why is Disk Management calling Drive D, Drive "0" and C drive, Drive "1"?
I have tried to move around the cables on the MB but with no luck, the drives stay the same in Disk Management. I'm rather curious as to why this is? Can anybody shed any light on this? Thanks in advance.
I hope I'm in the right place to ask this.

Raid 0 help

Hi all, I've followed the IRST raid installation directions and I have created myself a Raid 0 volume. Rapid storage confirms my successful migration from a system disc to a raid 0 array. I'm also able to select it as my boot device in BIOS, but what I don't understand is why it is not listed in my Drives under my computer

In fact, my computer still lists my original C: drive with the original capacity. I feel as if I've miss an important step here and I'm unsure how to proceed.

If you recently made some changes on your machine and needs to access
C: drive, you can do it by following the steps below:

• Press Windows key + E.
• On the left pane, click This PC. It will show you list of different folders. For
