Three factors drive the implementation of RAID configurations:
Fault Tolerance, (Drive Availability)
Performance
Capacity
The needs and priorities in regards to each of these factors determine the optimal RAID level and configuration for the
specific usage for which the RAID array is intended.
Maximizing Fault Tolerance
RAID Level
Fault Tolerance Description
0
Not fault tolerant. Drive failures are not tolerated.
1
Disk mirroring; a complete copy of data on a secondary hard drive. One drive failure can be tolerated.
