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:

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