I'm looking into setting up a 4 x 3TB RAID 5 array using a RAID controller card, possibly this one. My question is: in the future, would I be able to add another drive or two to the array and be able to resize the volume's size to incorporate the new disks? I.e. if the array starts out as a 4 x 3TB RAID 5 (so roughly 9TB of usable space) and I add two more 3TB drives, would I be able to expand the volume to be 15TB? Most notably, this would have to happen with the data remaining on the drives and not performing a new array build/rebuild. Is this possible at all and does the card I'm looking into support such a feature? Thanks for the help.
