It's probably your bdflush daemon flushing dirty buffers 

#  cat /proc/sys/vm/bdflush 

to check your settings. The docs are in:

/usr/src/linux/Documentation/sysctl/vm.txt

Be careful - an incorrectly tuned system can be screwed badly. You
probably want to tune age_buffer parameter from the 30s default. But
doing this means you'll lose more data in the case of a power failure.
