You could JBOD the 500 and the 1000 together and mirror that against the 1500GB. Disclaimer: I don't know if it makes any sense to do this. I haven't seen this method mentioned before, IIRC. It may be too esoteric to get any press, or it may be simply stupid. -- Kristleifur -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
