A stripe over two mirrors is not as reliable as RAID6. If you have 4 drives arranged in two mirrors, each mirror can only survive the loss of one drive. So, your system, if it loses 2 drives, has a 33.33% chance of losing half its data. > > -- > \m/ (--) \m/ > _______________________________________________ > Discuss mailing list > [email protected] > http://lists.blu.org/mailman/listinfo/discuss > _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
