Care to explain how? ZFS checksums everything what it writes so I guess
checksum can get bad data. In my experience memory fault caused bad files
which were detected. This is because I had overclocked memory too far
without testing. I had to clear zpool and restore faulty files.

I had memory corruption due suspend/resume which produced corrupted ext4
which had to be repaired with fsck , journaling didn't help.

BTRFS and ZFS are not fast, simply because they don't have destructive
update... but they are good for keeping snapshots and doing backups.
For databases? forget them...
