And journal of file system, especially if you not set "noatime" mount
option. WAL and file system journal like to make sync.
IMHO: on first disk (raid mirror:)) I place /, pg_table and file system
journal from second disk. On second /var and pg tables. Thus first disc
is synced time to time, second not.
