RAID 0 | What is RAID 0 ? | RAID
RAID 0 is a configuration of RAID, which is used to achieve performance speed. In this, the data is first striped into bits, bytes, or blocks and then written to all the drives in the array simultaneously. All the physical drives in the array are looked upon as a single logical drive. A minimum of 2 disks are required to set up a raid 0 array. Since disks are accessed in parallel, your read-write performance can be equal to the number of disks in your array when compared to single disk system performance. There is no fault tolerance so it can not be used for the data-critical systems. You can use RAID 0 where the main focus is on performance and low reliability is not an issue.
