RAID Levels

RAID 0 - Data Striping

Data blocks are split into stripes based on the adjusted stripe size (for example, 128 KB) and the
number of hard disk drives. Each stripe is stored on a separate hard disk drive. Significant
improvement of the data throughput is achieved using this RAID level, especially with sequential
read and write. RAID 0 (Figure 1) includes no redundancy. When one hard disk drive fails, all
data is lost. RAID 0 requires a minimum of two disks.
