ZFS does nothing to protect you against RAM corrupting your data before ZFS sees it. All you'll end up with is a valid checksum of the now bad data. You can Google more, but, I'll just leave this from the first page of the openZFS manual: Misinformation has been circulated that ZFS data integrity features are somehow worse than those of other filesystems when ECC RAM is not used. This is not the case: all software needs ECC RAM for reliable operation and ZFS is no different from any other filesystem in that regard.[1] [1] https://openzfs.readthedocs.io/en/latest/introduction.html https://openzfs.readthedocs.io/en/latest/introduction.html
