    A number of RAID configurations are available in the computer industry for different types of uses. The Dell mini tower and desktop models of your OptiPlex computer support RAID level 0 and RAID level 1. (RAID support is not available for the small form factor model.) A RAID level 0 configuration is recommended for high-performance programs, while RAID level 1 is recommended for users that desire a high level of data integrity.

  • Page 269: Verifying That Raid Is Working

    NOTE: If you purchased your Dell computer with RAID, your computer has been configured with two hard drives that are the same size. Verifying That RAID Is Working Your computer displays information pertaining to your RAID configuration at start-up, before loading the operating system.

  • Page 270: Raid Level 1 Configuration

    NOTE: In a RAID level 0 configuration, the size of the configuration is equal to the size of the smallest drive multiplied by the number of drives in the configuration. RAID Level 1 Configuration RAID level 1 uses a data-redundancy storage technique known as mirroring to enhance data integrity. When data is written to the primary drive, the data is also duplicated, or mirrored, on the second drive in the configuration.
