Media center seperate hardrive(s) question for videos

I am currently maxed out on my 2 tb harddrive and would like to add another harddrive. However, inside video library tab I do not want to have two seperate movie folders. How do I point Media center to add both of those folders into one larger folder.
I thought about doing a raid 0 or jbod setup but I dont want to lose my data if one goes. I understand in jbod they are less likely to lose all data but the risk is still there. Any suggestions would be great?

Think im gonna use media browser instead because they allow nesting of folders!! This would be nice if windows included it too!!

I dont think I like the downsides to having a spanned volume. LIke having to deal with one of the harddrives crashing. I realize that the chances of boot failure is less than a raid 0 but the chance is still there that all volumes across the hardrives could become corrupt. Also, I have a external sata swap drive so I like to be able to pull the drive out and replace it when I need another one of my drives. Was gonna use all 4 bays with 2 tb harrdrives(maxes out) but then swap out when I needed another one of my drives for something else!
