        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!!
