Interesting, I came up with the same results (1M chunk being superior) with a
completely different raid set with XFS on top:
mdadm --create \
--level=10 \
--chunk=1024 \
--raid-devices=4 \
--layout=f3 \
...
Could it be attributed to XFS itself?

Good question, by the way how much cache do the drives have that you are
testing with?
