I require a new high capacity 8 disk zpool. The disks I will be purchasing (Samsung or Hitachi) have an Error Rate (non-recoverable, bits read) of 1 in 10^14 and will be 2TB. I'm staying clear of WD because they have the new 2048b sectors which don't play nice with ZFS at the moment.
My question is, how do I determine which of the following zpool and vdev configuration I should run to maximize space whilst mitigating rebuild failure risk? 1. 2x RAIDZ(3+1) vdev 2. 1x RAIDZ(7+1) vdev 3. 1x RAIDZ2(7+1) vdev I just want to prove I shouldn't run a plain old RAID5 (RAIDZ) with 8x 2TB disks.
