I figured it out. I thought I'd post the solution for others that have had this question. Also shows what a newb I am, but I'm learning! When 2 drives are said in raid 0 or raid 1, windows sees them as 1 drive. I was able to prove that by resetting the 2 drives to raid 0. In disk manager windows still saw just one drive but the storage amount was double. If the 2 drives were NOT in a raid configuration, windows would see both drives.
