    Jun 10, 2024 · RAID (Redundant Array of Independent Disks) is a data storage method that integrates many disk drives into a single device to increase performance and offer redundancy. RAID 3 and RAID 4 are two RAID levels that employ separate parity drives to secure data against disk failures.

    RAID 1 (mirrored disks) It duplicates data across two disks in the array, providing full redundancy. Both disks are store exactly the same data, at the same time, and at all times. Data is not lost as long as one disk survives. The total capacity of the array equals the capacity of the smallest disk in the array.

    A RAID controller is a device used to manage hard disk drives in a storage array. It can be used as a level of abstraction between the OS and the physical disks, presenting groups of disks as logical units. Using a RAID controller can improve performance and help protect data in case of a crash.

    Jul 23, 2019 · RAID (redundant array of independent disks) is a setup consisting of multiple disks for data storage. They are linked together to prevent data loss and/or speed up performance. Having multiple disks allows the employment of various techniques like disk striping, disk mirroring, and parity.
