RAID 0 (striping)
RAID 0 uses the read/write capabilities of two or more hard drives working in unison to maximize the storage performance of a computer system. Data in a RAID 0 volume is arranged into blocks that are interleaved among the disks so that reads and writes can be performed in parallel (see below diagram). This technique, known as "striping", is the fastest of all of the RAID levels, especially for reading and writing large sequential files. Real world tasks where RAID 0 can be of particular benefit include loading large files into image editing applications, saving large movie files in a video editing application, or creating CD or DVD images with a CD/DVD authoring package.
The hard drives in a RAID 0 volume are combined to form one volume which appears as a single virtual drive to the operating system. For example, two 400 GB hard drives in a RAID 0 array will appear as a single 800 GB hard drive to the operating system.
No redundancy information is stored in a RAID 0 volume. This means that if one hard drive fails, all data on both drives is lost. This lack of redundancy is also reflected by the RAID level 0, which indicates no redundancy. RAID 0 is not recommended for use in servers or other environments where data redundancy is a primary goal.
| Minimum Disks: |

| Advantage: |
Highest transfer rates |
| Fault-tolerance: |
None - if one disk fails all data will be lost |
| Application: |
Typically used in desktops and workstations for maximum performance for temporary data and high I/O rate | |
