RAID without the R?

March 14, 2009

An associate is building a new database server that is configured with hard drives in a RAID 0 array. You know that RAID stands for “Redundant Array of Inexpensive Disks,” but your associate tells you that his RAID 0 array will not have any redundancy. Is your associate accurately describing RAID 0?

A) RAID 0 is used to describe a system that does not use multiple hard drives to enhance performance or provide additional availability.

B) RAID 0 does not provide drive redundancy, but it does split files across hard drives to improve performance.

C) RAID 0 does provide redundancy, and every file is duplicated and stored on separate physical hard drives.

D) RAID 0 does provide redundancy. Files are split across physical drives and a separate parity block is calculated and stored. In the case of a drive failure, the parity information is used to recreate the missing file data.
