"RAID (Redundant Array of Independent Disks) is often used to house financial and key business information. Whilst effective systems, they are not completely infallible. Legislation means that the amount of data companies are required to store is increasing at an alarming rate. Many employ RAID systems to manage their storage needs, protect their data and help avoid unnecessary downtime. Such systems are good for data protection as they allow data to be written to multiple hard disk drives, consequently increasing the system’s fault tolerance. However, RAID systems are still susceptible to total system failure, making data inaccessible if multiple drives experience problems at the same time."
