Hi again Albert, On our Thumper, we use 7x 6-disk raidz2's (750GB drives). It seems a good compromise between capacity, IOPS, and data protection. Like you, we are afraid of the possibility of a 2nd disk failure during resilvering of these large drives. Our usage is a mix of disk-to-disk-to-tape backups, archival, and multi-user (tens of users) NFS/SFTP service, in roughly that order of load. We have had no performance problems with this layout.
