Redundant Array of Independent (originally Inexpensive) Disks or RAID can be set up using hardware or software.Hardware RAID is more expensive, but offers better performance.Software RAID is cheaper and easier to manage, but it uses your CPU and your memory.Where ten years ago nobody was arguing about the best choice being hardware RAID, this has changed since technologies like mdadm, lvm and even zfs focus more on manageability.The workload on the CPU for software RAID used to be high, but CPU's have gotten a lot faster.[1]
