About RAID Configurations This section provides an overview of the RAID configuration that you might have selected when you purchased your computer. Dell offers RAID level 1 for its Vostro computers. 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. serial ATA RAID configured for RAID level 1 segment 1 segment 2 segment 3 segment 4 segment 5 segment 6 hard drive 1 segment 1 duplicated segment 2 duplicated segment 3 duplicated segment 4 duplicated segment 5 duplicated segment 6 duplicated hard drive 2 42 Setting Up and Using Your Computer
