I need to know this because of this:
Add the data=writeback mounting option if you formatted the disk without journaling. Otherwise add data=ordered which sould be a good compromise between full journaling and none at all.

, look for a line starting with Filesystem Features, should say has_journal.
To turn off journal and speed things up on a ext4 partition follow these steps:
Example uses sda1 device, this does not mean you should do it on your main disk, replace sda1 with the disk you are preparing, data loss will happen!
Create ext4 fs on /dev/sda1 disk
mkfs.ext4 /dev/sda1
To enable writeback
mode use this. This mode will typically provide the best ext4 performance.
tune2fs -o journal_data_writeback /dev/sda1
To delete journal remove has_journal option, this will disable etx4 journal
tune2fs -O ^has_journal /dev/sda1
Check if everything is ok
e2fsck -f /dev/sda1
Done, recommended for speed applications only! Gl
