Generally speaking, striping mirrors will be faster than raidz or raidz2, but it will require a higher number of disks and therefore higher cost to get the same usable space. The main reason to use raidz or raidz2 instead of striping mirrors would be to keep the cost down, or to get higher usable space out of a fixed number of drives. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
