noatime implies nodiratime as far as I know.

And yes, it can help for databases for example. I think official
recommendation for MySQL and PostgreSQL is to use noatime. There is a post
by Theodore T´so somewhere about make clean workload on Ext4 with noatime,
relatime and strictatime handling and only noatime considerably reduced the
amount of writes.

noatime is a generic tuning option which can help with other filesystems as
well.
