RAID 0 – Striping
In a
RAID 0
system, storage is split into blocks that are written split across all
the drives in the array. Using more disks in one RAID 0 system offers higher
storage rates. The performance also depends on the RAID controller used.

RAID 0 – Striping
Advantages
l
Great performance, both in read and write operations.
l
All storage capacity is used; there is no disk overhead.
l
Volume size grows with every extra disk added.
l
The technology is easy to implement.
Disadvantages
l
Not fault
-
tolerant. If one disk fails, all data is lost.
WARNING
It should not be used on mission
-
critical systems.
