segment 1

segment 2

segment 3

segment 4

segment 5

segment 6

hard drive 1

serial ATA RAID configured for RAID level 5

segment 1 striped across at least 3 drives

segment 2 striped across at least 3 drives

segment 3 striped across at least 3 drives

segment 4 striped across at least 3 drives

segment 5 striped across at least 3 drives

segment 6 striped across at least 3 drives

hard drives 2, 3 (and optionally, 4)

If a drive failure occurs, subsequent read and write operations are directed to the surviving drives. A replacement drive can then be rebuilt using the data from the surviving drives.

NOTE: In a RAID level 5 configuration, the size of the configuration is equal to the size 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 storage technique 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 1 configuration which writes to one other volume that acts as a data mirror, a RAID level 10 configuration writes data to each drive in increments which places data from each segment across multiple drives. A RAID level 10 configuration has higher data access rates but requires more storage space than a RAID level 0 or RAID level 1 configuration.
