What do you think about buying second hand disks and using higher redundancy?
For example 4x 16TB in RAIDz2? Is anyone using something like that? How’s it performing, reliability-wise?
E: Thanks all for the opinions and information!

I dunno, like I said zfs is pretty damn good at recovery. If the drives simply drop out but there’s no hardware fault you should be able to clear the errors and bring the pool back up again. And the chances of two drives failing at the same time are pretty low. One of these days I do need to buy a spare to have on hand though. Maybe I’ll even swap out one drive just to see how long it takes to rebuild.
Do it. The last thing you need during a rebuild is the stress of not knowing how long / other issues with your specific setup.
It’s only "disaster recovery* if you’ve never practiced… orherwise it’s just “recovery”
