Dan's point is that while ECC memory is indeed safer than non-ECC
memory, this is true whether one is using ZFS or some other filesystem;
furthermore, with or without ECC memory, there's no reason to believe
that ZFS is less safe than the alternative.

See:

https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/

So while ECC memory is always good, it's not a consideration when
trying to choose between ZFS and other filesystems.
