I would point out that a single write on a raid 5 or 6 requires multiple
reads and writes if the file is smaller than the blocksize... whereas this
is not the case with raid 1...

So as always it depends on the application, myth video recordings raid5/6 is
fine but for databases raid 1 or 10 will provide higher performance
