I try to avoid r/w contention by using full data journalling with external 
journals, which are on physically different (and hopefully faster) HDDs. I 
believe this is good practice for synchronous I/O like mail and NFS.

For real psychopathic I-don't-care-about-my-data cases you can always use 
tmpfs..
