Yes, you can. The optical drives will not be part of the RAID array,in other words, there will be no conflicts.
Thank you Allan for your response. It's appreciated.
I've been using onboard chipset Intel RAID's now since their infancy in the late 80's and have just recently had problems using on-board chipset array's. And it's only when I use the Rapid Storage Technology Management drivers within the monitoring software packages. I have UPS' and liked being able to turn on the additional write-cache for additional performance as it made about a 30% increase. Then corruption started occuring corrupting the entire RAID 10. Making it entirely unusable or recoverable. I thought maybe the optical drives were the reason but I believe it is in 'turning on the write cache' with having the optical drives attached. Or using all 6 ports.
Thank you again.
