I recently asked about this on the jack and ardour

he thought jackd might be reading the period buffer
and compensating accordingly--if "-p 512" then move
file to compensate for the inherint latency of that
period.
jackd itsself doesnt do it, but ardour can correct automatically given the
information that jackd provides, I think.
I've got to setup a session but will come back to
learn more about the RAID latency issues that you're
outlining. BTW, I'm running RAID 5 but have thought 10
would be optimal for performance but expensive.
Coincidentally I was talking with a sysprog over coffee about raid 10 and
he said that the survivability of raid 10 was not as good as 5, there are
relativly likely disk loss patterns that can cause you to loose all the
data, when a raid 5 setup with the same (or less) redundancy could
survive. He mentioned it cos it actually happened over the weekend :(
I dont know how the performance compares. I've always used 0 for raw
throughput and terrible survivability, or 5 for robustness and a bit extra
speed.
