RAID is short for Redundant Array of Independent Disks. In the storage industry, the speed, redundancy, and cost are the three factors that the market cares about. I/O speed: hard drive's I/O performance is limited by the physical law, if we continue to use magnetic storage materials. redundancy: the fault of a subset disks in an array can't damage the whole data stored in them. cost: the density of data per dollar. RAID is a common solution to face that. 2 RAID's types 2.1 type 0 parallel multi disks together, with the highest disk write/read IO performance, but none data security. split the data into n pieces, n equals to the array size of the disks. And both the write and read are parallel to improve the speed, but one disk's damage c...
