Adding Hard Drive to Perc H710

We have a Dell T320 tower server with a Perc H710 and 3 - 2Tb SAS hard drives configured in RAID5. The 3 physical hard drives are configure with 2 virtual drives, 0 and 1.  0 is the OS and 1 has all the live data.  All of this is done on Connector 0.  I see that there is a Connector 1.  My question is, can I add 3 identical hard drives to be used as a totally different data drive and set them up as RAID on Connector 1. Is so, how? Basically I want to increase my storage capacity without touching my existing OS (Virtual dirve 1) or Data (virtual Drive 2).   Below are the Open Manage screen shots.
