Figure 3-1. Concatenating Disks
• Concatenates n disks as one large virtual disk with a capacity of n disks.
• Data fills up the first disk before it is written to the second disk.
• No redundancy data is kept. When a disk fails, the large virtual disk fails.
• No performance gain.
• No redundancy.

RAID Level 0 (Striping)
RAID 0 uses data striping, which is writing data in equal-sized segments
across the physical disks. RAID 0 does not provide data redundancy.
