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!

For hard drives I’d never trust them used with data I care about. Especially big drives like that that would take AGES to rebuild.
For enterprise grade SSDs I’d kinda yolo it for a system I care a bit less for, or as a cache drive. But not HDDs.
What if you can do a 2 or 3 disk redundancy?
The biggest fear would be when you’re rebuilding, you’re putting extra stress on the other drives, thereby increasing the risk of them, too, dying.
I suppose using mirror vdevs technically also puts stress on drives during rebuilding, however it should be significantly less than on drives in RAIDz.
