            Yes I know, I know....  Desktop hardware sucks. Didn't know there was
    Enterprise (ie none Desktop) SATA. Perhaps the solution is to  partition
    the data and do "deep" storage that never gets read on large bulk SATA and
    then have a smaller SAS pool for the often read/written stuff.

          Anyway, large storage rollouts will always be looking for
    the cheapest solution. Even if it isn't perfect. I do backups
    to a SATA pool (behind SAS expanders) with zfs send,.. no problems errors
    whatever YET!!
    (cross fingers)
