Well, they won't be better off a data integrity point of view.
Depending on how SQLite is configured, and how many fsync's are issued
by SQLite in response to application queries, and depending on your
background workload by other applications, using data=journal *might*
be a performance win.
In general, though, if you have background workloads that are
downloading torrents, data=journal is going to hurt a lot. So I don't
recommend it except for fairly specialized deployments where there's
only one primary user of the file system.
