you need to insert random seeks.
Neil, thank you for the time and effort to

I have not done any testing with the md native RAID10 implementations,
so perhaps there are some other advantages, but have you tried

By any chance did you remember to increase stripe_cache_size to match
the chunk size? If not, there you go.
At the end of /usr/src/linux/Documentation/md.txt it
