RAID-0
This RAID level uses striping without parity. Striping breaks data into small pieces and then simultaneously writes or reads
to multiple locations. This increases your computer's performance and data storage capacity.
RAID- 0: Striping without parity
Best uses for RAID-0
This RAID level is appropriate for situations where read/write performances is more important than data security. Some
examples are environments that use high bandwidth software programs for video production, video editing, or pre-press
production.
RAID-0 limitations
RAID-0 does not provide fault tolerance. All computer data on the array is lost if a single drive in the physical array fails. This
RAID level is not a true RAID configuration, as it does not provide redundancy. When using a RAID-0 array, your data
storage capacity may be increased, but is limited to twice the size of the smallest hard disk drive in the array. As an
example, if your array uses a 60 GB drive and a 20 GB drive, your total hard disk drive volume is 40 GB. The remaining space
on the larger drive is not available for use.
