Other than a single drive letter, RAID 0 provides no benefit with SSD's, and brings significant detriments.
Is there any reason you can't just use 1 for the OS and applications, and put the movies, etc on the other drives? If you redirect where the Libraries save to, it is pretty transparent, no matter how many actual drives.
Movies saves to this one, Music saves to that one, etc...
You, the user, just see 'Music'
