ZFS ECC nevyžaduje o nic míň ani víc než jiná FS. Viz značně výmluvný článek zde: https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/ Na konci je odkaz na komentář Matthew Ahrense: "There's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem. If you use UFS, EXT, NTFS, btrfs, etc without ECC RAM, you are just as much at risk as if you used ZFS without ECC RAM. Actually, ZFS can mitigate this risk to some degree if you enable the unsupported ZFS_DEBUG_MODIFY flag (zfs_flags=0x10). This will checksum the data while at rest in memory, and verify it before writing to disk, thus reducing the window of vulnerability from a memory error.
I would simply say: if you love your data, use ECC RAM. Additionally, use a filesystem that checksums your data, such as ZFS."
