How does RAID 0 improve performance?

There are two main benefits of using a RAID system. They are improved performance and fault tolerance. There are several different RAID configurations that provide fault tolerance but RAID 0 is the only one that does not. Instead RAID 0 provides a performance boost. So how does RAID 0 provide that performance boost?

RAID 0 provides a performance boost by dividing data into blocks and spreading them across multiple drives using what is called disk striping. By spreading data across multiple drives, it means multiple disks can access the file, resulting in faster read/write speeds. 

The disadvantage of using RAID 0 is that there is no parity or data redundancy built into the system in the event of a drive failure.

RAID 0 is best used in environments where high-speed read/write speeds are needed such as live streaming video and video editing. However, make sure that any data stored on a RAID 0 configuration is non critical or that a master copy is easily available for recovery from another storage system.
