Well, you can use this drive as a separate "scratch area", as a separate single-disk pool, without redundancy. You'd have a separate spindle for some dedicated tasks with data you're okay with losing. You can also make the rpool a three-way mirror which may increase read speeds if you have enough concurrentcy. And when one drive breaks, your rpool is still mirrored. HTH, //Jim Klimov
