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!

      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.
