You misunderstand journalling then

A journalling file system can offer different levels of guarantee. With
metadata only journalling you don't take any real performance hit but your
file system is always consistent on reboot (consistent as in fsck would pass
it) but it makes no guarantee that data blocks got written.

Full data journalling will give you what you expect but at a performance hit
for many applications.
