Seems to be the ext4 journaling doing its thing. You can increase the interval (in seconds) by adding for example
commit=60
to mount-options in /etc/fstab, or disable it altogether with
tune2fs -O ^has_journal /dev/sda5 e2fsck -f /dev/sda5
(or whatever your disk is called). Your disk will be more vulnerable for data corruption on uncontrolled shut-downs without journaling.
