Since hardware RAID 5 implementations usually do not checksum data (they only compute the parity, which is not the same thing), for an apples-to-apples performance comparison you should have benchmarked raidz with checksum=off. Is it what you did ? -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
