<Why not partition the array into two partitions?>
Good answer. However, Windows wouldn't let me do that. It listed the disk space as about 2782GB but it listed everything over 2047 as unavailable. I don't know why.
Anyway, I really don't want to make two partitions because my whole reason for having a RAID array was to have only volume.
Besides, I wouldn't learn anything. I like trying new stuff just to find out if I can make it work and this is my first time trying to setup a RAID array.
The link to that article looks like it will do the trick.
