I expect to see data transfer rate increase when you break the mirror.
RAID1 has the higest disk overhead of all RAID configurations and is
very inefficient in that regard. It would be interesting to see
performance results with the bad disk still attached to the mirror.
Unfortunately I am not able to break disks on a whim so I can't test
it out. :P
