Raid Levels explained

Top Raid 0 Raid 1 Raid 3 Raid 5 Raid 10 Raid 0+1


RAID 0

Offers no redundancy or fault tolerance, hence does not truly fit the "RAID" acronym. In level 0, data is striped across drives, resulting in higher data throughput. Since no redundant information is stored, performance is very good, but the failure of any disk in the array results in data loss. This level is commonly referred to as striping.


Advantages

  • No parity generation
  • Easy to implement
  • Cost effective
  • Utilises full disk capacity

Disadvantages

  • Not a true RAID
  • No redundancy / fault tolerance
  • Drive failure will result in data loss
  • Not suitable in mission critical environments

Applications

  • Pre-Press
  • Video editing and production
  • Image manipulation/editing

 

Dual controller Raid 0 offers better performance than a single controller
