A RAID array is a group of disks set up to work like one big disk, with the special feature that, even if one of the disks in the array has a failure and stops working, all the data are still available on the other disks in the group. Such arrays have been commercially available since long before 1996, and are a standard way of storing data for high availability. But these brilliant inventors have patented the use of a RAID array for this particular purpose.
