Improved I/O performance is the major reason of using RAID
level 0.
No protection is provided against data loss due to member
disk failures. A RAID level 0 array by itself is thus an unsuitable
storage medium for data that can not easily be reproduced,
or for data that must be available for critical system operation.
It is more suitable for data that can be reproduced or is
replicated on other media.
A RAID level 0 array can be particularly useful for :
Storing program image libraries or runtime libraries for rapid
loading, these libraries are normally read only.
Storing large tables or other structures of read only data for
rapid application access. Like program images, the data
should be backed up on highly reliable media, from which it
can be recreated in the event of a failure.
Collecting data from external sources at very high data
transfer rates.
RAID level 0 arrays are not particularly suitable for :
Applications which make sequential requests for small
amount of data. These applications will spend most of their
I/O time waiting for disks to spin, whether or not they use
striped arrays as storage media.
Applications which make synchronous random requests for
small amounts of data.
