generally speaking the re or enterprise drives are all I use
in production (all of production is software raid'd.) otherwise,
even though you have a mirror, if one drive fails in a certain
way (happened to me twice before I switched to 'enterprise' drives)
the entire box hangs waiting on that one bad drive.
