What types of RAID are there?
There are multiple types of RAID. Discussed so far have only been the most common. Below is a comprehensive list of the types of RAID. Only the most common will be fully explicated. • RAID 0 – This type of RAID is a striping array and requires a minimum of two drives to implement. In this configuration, data is written sequentially in equal parts, called blocks, to all drives in the array, maximizing the space used on all drives, and read from the drives simultaneously to increase the read speed. Disk speed is maximized in this configuration. Because of this it is favored for applications that require very fast response times, such as video editing and databases. Because data is only striped across disks, this is not considered true RAID: the data is not redundant and the failure of any drive in the array will result in the loss of all data on all drives. Drives used in this type of array must be of the same size; differences in size will result in the size of each disk in the array be
