Either the RAID 1 read speed must be wrong, or something is odd in the
Linux implementation. There's six drives that can be used for reading
at the same time, as they contain the very same data. 63MB/s
sequential looks like what you would get from a single drive.
The RAID1 is correct. As has been discussed on this list before, you will
only see raid speed > 1 disk if you run 2(?, or 3 minimal) threads
from the same device (raid1).
