Actually with 3-disk RAID5 you get 2x the space of RAID1 for 1.5 x cost, so the factor is 1.5/2 = 0.75, i.e., you save only 25% on RAID5 or RAID1 is 33% more expensive. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
