Raid 10 (one-zero, not ten), is the best. It has mirrored striping and the controller can access multiple areas at the same time, which increases disk speed by 200% compared to a single, non-raided drive.
It also beats the reliability of Raid 5 by far, since Raid 5 will destroy all data if 2 drives fail.
Raid 10 is a backup system itself, you don't need to take backups if you have the system alert you when 50% of the drives fail (hopefully even when 1 drive fails).
