Benefits of RAID?

[stiper327b]

Ok, I'm looking to build a new comp, mainly to use for heavy duty video editing, hopefully with Avid XPress. Regardless, my question is, what are the benefits of RAID over regular IDE drives? Is it a question of speed, security, or both? Any help would be good. Thanks.

Depends on how the raid is setup
