The original comment did not claim that ZFS specifically needs ECC to run correctly. Quote the OP, > With ZFS allowing for very robust data integrity on disk, the weak point in most budget NAS setups these days is going to be memory errors. You see, it didn't say "no ECC, no ZFS." It merely says: if your goal is to eliminate data corruption, once you've removed filesystem errors from the equation by using ZFS, the next term to eliminate is memory errors - which is entirely correct.
