I agree with Michael. I would use 2 disks in a RAID 1 for the log files and
add those other two disks to the other Raid 1+0 and place all the files
there. Yes you can get increased performance by placing data and indexes on
separate arrays but probably not as much overall gain from adding more disks
to the Raid 1+0 and separating the logs.
