I frequently defragment systems that are running an High Speed, High Availablity XP arrays.
I think it helps a lot, when needed.

Unless the drives are extremely full and contiguous space is rare, I don't
see the value in frequent defragging. Quarterly? Maybe. Daily? No.
Not sure if defragging an auto raid is useful or even recommended. May not
be a problem to do it, but auto raid takes so much disk allocation out of
the OS's hands it may just ignore the entire process.
