It's one of the big selling points, reasons for ZFS to exist. You should always give ZFS JBOD devices to work on, so ZFS is able to scrub both of the redundant sides of the data, and when a checksum error occurs, ZFS is able to detect *and* correct it. Don't use hardware raid.
That isn't the recommended best practice, you are stating it far too strongly.
The recommended best practice is to always create ZFS pools with redundancy in the control of ZFS. That doesn't require that the back end storage be JBOD or full disks nor does it require you not to use hardware raid. Some of all of which are impossible if you are using SAN or other remote block storage devices in many cases - and certainly the case if the SAN is provided by a Sun ZFS Storage appliance.
