I recently asked about this on the jack and ardour
developers list. I think Jan replied by stating that
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.

Six months ago when I produced an album in Ardour, I
did a bunch of nudging on files but I think it was bug
related issues with Ardour that were causing peak
files to misalign. I'm not seeing that behaviour now.

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.
