InnoDB and separated disks

Hi all,
I currently use a server with 2 separated volumes (2 * 4 physical disks in RAID 10 mode).

I know I improved performances by using second volume to store InnoDB log files and binlog.

I could also move some big tables to second volume.

However, I am wondering if I couldn't obtain better results by using 8 physical disks in a single big volume. I suppose the 4 disks of first volume do 95% of workload.

One other question : I use innodb_file_per_table = 1. Should I move ibdata1 to second volume ? I don't know if ibdata1 is intensively used with per_table set to ON.

Many thanks,
