RAID-0 is shorthand for RAID Level 0: Striped disk array without fault tolerance

RAID Level 0 is a type of RAID configuration which uses 2 or more disks to increase performance. As it provides no redundancy, many people believe it shouldn't really be classified as a RAID type at all.


  • Availability: Cannot tolerate any drive failure, loss of any disk will result in all data being lost. Worse than a single disk, as each additional drive and controller becomes an additional point of failure.
  • Capacity: 100% (2 drives = 2 drives available space)
  • Degradation: N/A
  • Performance: Highest read speed, highest write speed
  • Summary: Should never be used for critical data, but an excellent way to increase drive speed.
  • Typical Uses: Video production and editing, image editing, high-end gaming, scratch disks.

How it works

  • READ: read data stripes from 2 or more disks at the same time
  • WRITE: write data stripes to 2 or more disks at the same time

Comparison with other RAID types:

  • RAID-1 has slower writes and equal read speeds to a 2-drive RAID-0 set (RAID-1 is max 2 drives)
  • RAID-5 has slower writes and equal read speeds to a 3-drive RAID-0 set (RAID-5 is min 3 drives)
