interesting
by default ntfs is faster than ext4 under Ubuntu ;)
you can change your mount options for ext4
you will certainly find this kind of post interesting :

but I'm not a Ubuntu fan, and I don't know what options they use by
default and their kernel settings
so read, ask to Ubuntu users, test
