The disk array is made up of many inexpensive disks, combined into a large disk group, which uses individual disks to provide data with the added effect to improve the performance of the entire disk system. Using this technology, the data is cut into many sections, stored on each hard drive, even if there is a piece of damage, no data loss, and can continue to use. Introduction to RAID (disk
