I assume that you with 20 TB mean the payload space in both places, that is for the Linux MD RAID10 you actually have 40 TB of raw disk space. With the Linux MD raid10 solution you furthermore can enjoy an almost double up of the IO reading speed, involving 20 * 2 TB spindles compared to 12 * 2 TB spindles. best regards keld -- 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
