RAID-0
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.
Features:
- 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)
