I have 2 terabyte drives in a RAID 0 config. It has Intel Rapid Storage Technology Enterprise Software and an Intel C600 Series Chipset SATA RAID Controller.
I have a new drive on the way, What will I need to do to go from RAID 0 to RAID 5?
You do not need anything. One of the three drives will be used to store parity info. The array size is twice of the smallest drive. It is best if all the drives are the same.
