Requires a minimum of 2 drives to implement.

Characteristics and advantages

RAID 0 implements a striped disk group. The data is split into blocks and these are written to separate disk drives.
I/O performance is greatly improved by spreading the I/O load across multiple channels and drives.
The best performance will be achieved when the data is striped across the drives using one controller per drive.
There is no parity calculation overhead involved.
The design is very simple and easy to implement.

Disadvantages

This implemetation is not a "True" RAID as it is NOT fault-tolerant.
A failure of just one drive will result in all data in the array being lost.
Therefore it is not recommended in mission critical environments.

Recommended applications

It is recommended in any application requiring high bandwidth, such as Video Production and Editing or Image Editing.

A block is sometimes called a stripe. The Stripes will have a pre-defines size, called stripe-size. The stripe-size will be equal in size across the same disk array.
