Correct. Maybe someday, but not now. > In this case, what needs to be out of the array? Example, on a Linux > system, I could set the /boot to be on a old 256MB USB flash.

Really, your better alternative would be to carve out a slice on each disk to configure as a ZFS mirror. Install into one of them, add the additional ones to the mirror, then configure the remaining space on the disks as your raidz pool. Or just install to a 8 GB USB drive (they're cheap now) and use the SATA disks for data. Dave
