I have 12@3TB drives arranged in as a 2x6 drive vDev Raid Z1 pool. I know that RaidZ1 is a bad choice but my rational is that this backup pool stores data that is primarily stored on a RaidZ2 array. Also, any truly irreplaceable data is stored on a cloud service.
My question is this: is it better to use the 2x6 drive Z1 setup or a 1x12 drive Z2 setup. Given that this pool does nightly incremental backups, performance is not a factor. I know that 12 wide is not recommended. Fundamentally though, which option is more resilient? Also, given that I have the 12 drives, is there any other backup pool arrangement that I should consider?
And a note about my backup pool: I have suffered a few catastrophic drive failure thanks to the oh-so-wonderful Seagate 3TB drives without any data loss on my backup pool. So far, Z1 has been fine for my needs (knock on wood!!).
Cheers,
