Some defaults are not good for servers. For example, systemd gives up after a few tries to restart a service. This is really annoying for server administrators when they don’t know about the bad defaults.
It doesn't have to be the same exact drive. Mixing drives from different manufacturers (with the same capacity) is often used to prevent correlated failure. ZFS is not using the whole disk, so different disks can be mixed, because the disk often have varying capacity.

I can confirm that mold causes joint pain. I even had increased anti-CCP antibodies that correlated with my joint paint. Sadly there was no treatment for me because RA diagnosis is not possible without joint swelling. The only thing I can do is to avoid mold. When I avoid mold, I have no joint pain and also my antibodies are normal again. It’s scary to know that mold is slowly destroying my joints.
I think my real problem is MCAS but doctors don’t seem to know or treat it.
