ZFS can do mirror configurations without problem. Regarding faulting the RAID to take one of the drives as a snapshot: be careful that reconstruction of the new drive puts a non-standard stress on the drive that's still in the system (higher the bigger is the drive), and it may increase the risk of it dying during the process, taking down the whole system.
