* Ditto blocks: Metadata is replicated inside the pool, two or three times (according to metadata importance).[8] If the pool has several devices, ZFS tries to replicate over different devices. So a pool without redundancy can lose data if you find bad sectors, but metadata should be fairly safe even in this scenario.
* ZFS design (copy-on-write + uberblocks) is safe when using disks with write cache enabled, if they \\\"obey\\\" the \\\"cache flush\\\" commands issued by ZFS. This feature provides safety and a considerable performance boost compared with other filesystems.
