Which filesystem?  If these things are ext3, then one thing that might help is
to fiddle with the commit= option.  The default for ext3 is 5 seconds, so if
you're mounting it with the defaults, all the filesystems will commit their
metadata every 5 seconds.  This leads to more disk I/O than is usually
necessary.  commit=600 (10 minutes) would probably work reasonably well.
