As for whether or not to do raidz, for me the issue is performance. I can't handle the raidz write penalty. If I needed triple drive protection, a 3way mirror setup would be the only way I would go. I don't yet quite understand why a 4+ drive raidz3 vdev is better than a 3 drive mirror vdev? Other than a 6 drive setup is 3 drives of space when a 6 drive setup using 3 way mirror is only 2 drive space.
That's a pretty big "other than", since the difference is 50% more space for the raidz3 in your case, and the difference grows as the number of drives increases. I concur with some of the other thoughts, that migration towards L2ARC + big slow sata pools is becoming a more recommended configuration. The recent automated pool recovery and ZIL removal improvements makes that design much more practical. --eric -- Eric D.
