> ZFS is notorious for corrupting itself when bit flips hit it and break the checksum on disk

ZFS does not need or benefit from ECC memory any more than any other FS. The bitflip corrupted the data, regardless of ZFS. Any other FS is just oblivious, ZFS will at least tell you your data is corrupt but happily keep operating.

> ZFS' RAM-hungry nature

ZFS is not really RAM-hungry, unless one uses deduplication (which is not enabled by default, nor generally recommended). It can often seem RAM hungry on Linux because the ARC is not counted as “cache” like the page cache is.

ZFS docs say as much as well: https://openzfs.github.io/openzfs-docs/Project%20and%20Commu...



And even dedup was finally rewritten to be significantly more memory efficient, as of the new 2.3 release of ZFS: https://github.com/openzfs/zfs/discussions/15896
