The world of Raid Drives is new to me.

Mac Pro 2.6gb
I have 1 x 250gb boot drive. Catalyst application.

2 x 250gb striped Raid Pair (500gb) where media is stored.

I have been reading up on raid drives and I am wondering if I would be better with a mirrored raid config.
It is my understanding that this would improve seek times.
I am also wondering if this would help when sending same content to 2 outputs.
