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

RAID (Redundant array of inexpensive disks) is referred to as a disk array, combining multiple hard disks into a single logical sector, so that the performance of poor performance of the hard drives, to reach even more valuable, larger capacity of the hard disk. and increase the data integration, fault tolerance, processing capacity, capacity.
