Hello. Ext file systems are journaling file systems. There is journaling mode by default. If we want to increase FS speed we could disable journaling. It could be pretty useful for builds for instance because we shouldn't guarantee data integrity. For disabling journaling unmount device and do next commands:
umount /dev/sdb
tune2fs -O ^has_journal /dev/sdb
reboot
After that you could test your FS performance by dd command:
dd if=/dev/zero of=/<where sdb mounted>/somefile bs=1M count=1000
