If the array goes into the faulted state, you can just reboot and if the drive that was kicked out responds it will be brought back into the array and a scrub/resilvering will begin. Now if you have a failing drive, you can coax it back to online status by powering off your computer and letting it rest and a certain percentage of the scrub has completed. I've used ZFS with seagate green drives that were definitely not meant for that purpose but since they would be 99% read-only drives, once I got the data copied (which involved drives being kicked for poor performance) they perform just fine. They could not cope with continuous I/O however and would start to error out during heavy writes or long scrubs.
