} My understanding is that raid5 and raid6 write performance is sensitive 
} to the size of writes compared to the stripe size. Assuming that is true 
} what would be the optimal stripe size for a mythtv raid5 for recording 
} HDTV? Can the size of mythtv read and write sizes be adjusted to improve 
} performance for a storage group on a raid5 array?

true, but this falls under the hurry up and wait category.
even the worst performaning raid is faster then hdtv needs.
bad raids give 20M/sec, uber HD signal needs about 5M/s.
