Parity: This is a determined number used to recreate data mathematically.Mirroring: Data is replicated between multiple drives.Striping: Data is split across many drives.The following are concepts that are often associated with RAID:

Similarly, although RAID makes your entire storage system more robust, it is still just a single copy of your data. Therefore, whereas backup and restore solutions are designed to get your systems going in the event of catastrophic loss of data, RAID is intended to prevent such loss from occurring. In contrast, data backup allows you to recover lost files. RAID arrays distribute I/O operations over numerous disks to access and store data more quickly or replicate information on one disk across other disks, allowing the system to continue functioning sans data loss if one of the drives crashes. According to how it records and distributes your data, each RAID type offers unique advantages to its customers, including enhanced performance, higher fault tolerance, or a mix of both.Īlthough RAID may render company data storage more robust and reliable, it is not the same as data backup. Different configurations, including RAID 0, RAID 1, and RAID 5, are stated as numbers. “Redundant array of independent disks” is a form of storage that writes data to many disks in the same system. Redundant array of independent disks – abbreviated as RAID – is defined as a storage technology that combines multiple hardware disk units into a virtualized logical unit to improve the performance, reliability, and ease-of-access of data storage.
