Is the data=journal option really wanted here? Did you try with the
other journalling modes available? I also think you are missing the
noatime option here.
The wiki has some information about raid math and ext3 journalling
modes: http://wiki.centos.org/HowTos/Disk_Optimization

This is the case in data=journal mode; the server has to write the data
twice on disk.
