2 disks mirrored together can read data faster than a single disk. So to service a read only one side of the mirror is read. Raid-Z parity is only read in the presence of checksum errors. > Thanks, > > Jon > > > > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
