Something on your system must be causing writes to the filesystem;
turning off journaling might lower the total number of writes, but it
won't make this problem go away altogether.

I'd check /var/log to see what might be causing log messages (the most
likely cause) and see if you can disable or lower the syslog threshold
so that they don't get written to disk.
