What you are suggesting is called RAID 1+0, or RAID10 (raid ten) for short. It is always better to mirror disks first and then do striping, rather than create a mirrored stripe set. If you stripe first and then mirror and you lose a drive, the entire stripe set is disabled. If you mirror two disks at a time and then stripe, you can survive multiple disk failures.
