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 drives. Each stripe is stored on a separate hard 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 drive fails, all data is lost. RAID 0
requires a minimum of two disks.
