small change... but.. well the pain of a layout change is probably not
worth it
What is the change required to Linux RAID-1?
Why does disk layout even matter? If a test involves only reads then it
shouldn't matter where the data is, for two processes doing reads at the same
time the performance should be about double with two disks regardless of
layout.
