Setting Up and Using Your Computer 41About RAID ConfigurationsThis section provides an overview of the redundant array of independent disks(RAID) configuration you may have selected when you purchased yourcomputer. Your computer supports RAID level 1. A RAID level 1 configurationis recommended for the data integrity requirements of digital photographyand audio.The Intel RAID controller on your computer can only create a RAID volumeusing two physical drives. If a third drive is present, then that drive cannot bemade 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 fourdrives are present in your computer, then each pair of drives can be made intoa RAID level 1 volume. The drives should be the same size in order to ensurethat the larger drive does not contain unallocated (and therefore unusable) space.RAID Level 1 ConfigurationRAID 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 accessrates for its data redundancy advantages.hard drive 1segment 1segment 2segment 3hard drive 2segment 4segment 5segment 6segment 1 duplicatedsegment 2 duplicatedsegment 3 duplicatedsegment 4 duplicatedsegment 5 duplicatedsegment 6 duplicatedserial ATA RAIDconfigured forRAID level 1
