Chris,
you will see the help of stripe when you perform IO where disk head is the
bottleneck. For example try to dd a file > 2x RAM size. Then dd with stripe.
you will note that the 'rock bottom throughput' is lifted higher with
stripe. It also helps when one file is accessed by a LOT of clients so that
one machine's IO does not become a bottleneck.

Hi again,
So I did my dd read test of my 24MB file on a simple two brick
stripe. Nothing fancy. Two bricks and the stripe define on the server
side. Client side mounts the remote stripe. Default block size,
128KB.
No difference between that and my single brick test as far as
time goes. What's striping supposed to get me? I thought it was
drives heads. Or am I missing something again?
