I really don't know where the "You gotta have ECC RAM!" thing started. I've been running a ZFS RAID on Nvidia Jetson Nanos for years now and haven't had any issues at all with data integrity.

I don't see why ZFS would be more prone to data integrity issues spawning from a lack of ECC than any other filesystem.

Relevant quote from one of ZFS's primary designers, Matt Ahrens: “There's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem. ... I would simply say: if you love your data, use ECC RAM. Additionally, use a filesystem that checksums your data, such as ZFS."

Yeah, I remember reading that a few years ago.

If I were running a server farm or something, then yeah, I'd probably use ECC memory, but I think if you're running a home server, then the argument that ZFS necessitates ECC more than Ext4 or Btrfs or XFS or whatever doesn't really seem to be accurate.

Agreed.

Then you should still use ECC RAM, regardless of what filesystem you're using.

No, really. ECC matters (https://news.ycombinator.com/item?id=25622322) generally.

Fair enough, though AFAIK none of the SBC systems out there have ECC, and I generally use SBCs due to the low power consumption.

Years ago I saw it at:

(the gist of the scary story is that faulty ram while scrubbing might kill "everything".) However, in the end ECC appears to NOT be so important, e.g., see
