Thanks for the advise, I'm not very good at reading block text but i think i have a better understanding,
What i've gathered please correct me if i'm wrong. Is i dont need to raid all my drives. what i should do is buy a 2tb+ drive to be my parity on the server. use one of the 600gb drives to be my catch drive keep the two 600gb drives i have as raid 1 and off the aray for camera system and then then 2x tb and the 4x 600gb drive i raid as raid 5 to be the main storage on the server or do i not even need to raid my 600gb drive and just add them as normal. Watched some videos and seems like they dont bother raiding there HHD and just use the parity as there fail safe
But i dont understand what you mean with the dell raid card. as it only allows me to make one raid so i was just going to use the Virtual drive on the server to raid my hhd
