About RAID Configurations

NOTE: RAID is not supported on Inspiron 530b/530d.

This section provides an overview of the redundant array of independent disks (RAID) configuration you may have selected when you purchased your computer. Your computer supports RAID level 1. A RAID level 1 configuration is recommended for the data integrity requirements of digital photography and audio.

The Intel RAID controller on your computer can only create a RAID volume using two physical drives. If a third drive is present, then that drive cannot be made part of a RAID volume using the Intel RAID configuration program, although it can be used as a spare drive in a RAID 1 configuration. However, if four drives are present in your computer, then each pair of drives can be made into a RAID level 1 volume. The drives should be the same size in order to ensure that the larger drive does not contain unallocated (and therefore unusable) space.

RAID Level 1 Configuration

RAID level 1 uses a data-redundancy storage technique known as "mirroring." When data is written to the primary drive, it is then duplicated, or mirrored, on the other drive. A RAID level 1 configuration sacrifices high data access rates for its data redundancy advantages.
