46 About RAID ConfigurationsIf a drive failure occurs, subsequent read and write operations are directed tothe surviving drives. A replacement drive can then be rebuilt using the datafrom the surviving drives.NOTE: In a RAID level 5 configuration, the size of the configuration is equal to thesize of the smallest drive in the configuration multiplied by three.RAID Level 10 (1+0)RAID level 10, also known as RAID level 1+0, uses a data-staging storagetechnique known as data parity. When data is written to the primary drive,the data is then duplicated on four other drives. Unlike a RAID level 1configuration which writes to one other volume that acts as a data mirror, aRAID level 10 configuration writes data to each drive in increments whichplaces data from each segment across multiple drives. A RAID level 10configuration has higher data access rates but requires more storage spacethan a RAID level 0 or RAID level 1 configuration.hard drive 1segment 1segment 2segment 3hard drives 2, 3 (and optionally, 4)segment 4segment 5segment 6segment 1 striped across at least 3 drivessegment 2 striped across at least 3 drivessegment 3 striped across at least 3 drivessegment 4 striped across at least 3 drivessegment 5 striped across at least 3 drivessegment 6 striped across at least 3 drivesserial ATA RAIDconfigured forRAID level 5
