every machine I have that can fit 2 SSDs (basically, everything except the very slim laptops) I have converted over to running a ZFS mirror as its root filesystem. NixOS makes this very easy to do because the grub.mirroredBoots option [0] removes the need for a separate "bootpool" with limited ZFS feature flags. and crucially, I always make sure they're 2 drives from different manufacturers, so that a bug of this nature should never be able to take down both drives in a pool simultaneously. I think of this as the "if you're going to go to the trouble of wearing a belt and suspenders, make sure to buy them from separate brands" principle. 0: https://search.nixos.org/options?channel=22.11&show=boot.loader.grub.mirroredBoots https://search.nixos.org/options?channel=22.11&show=boot.loa...
