I am now finishing the actual copy that I was unable to complete. The reason I ask about the raid is that it writes so slowly that I wonder i= f it is just the looping thread or maybe there is something more. The large difference between what the array reports compared to what the members show (in iostat -x) is beyond what I expected as the array write amplification. I will keep watching this thread.
