Disk arrays are storage systems that link multiple physical hard drives into one large drive for advanced data control and security. Disk arrays have several advantages over traditional single-disk systems. A hard disk, while being the vital center of any computer system, is also its weakest link. It is the only critical device of a computer system that is not electronic, but relies on intricate moving mechanical parts that often fail. When this happens, data is irretrievable and unless a backup system has been employed, the user is out of luck. This is where disk arrays make a difference. Disk arrays incorporate controls and a structure that pre-empts disaster. The most common disk array technology is RAID (Redundant Array of Independent Disks). RAID utilizes disk arrays in a number of optional configurations that benefit the user. One advantage of RAID disk arrays is redundancy of data writes so that if a file is damaged or stored in a bad cluster or disk, it can be instantly and tra
