Which RAID mode is best for my server?
Tags:
Picking the correct RAID mode is important, especially as data carries a large value. Whether you need speed or redundancy, or both, you must pick the right RAID mode for your environment. There are other factors at play, such as read and write speeds, which we will discuss in the advantages and disadvantages below.

RAID 0:
ADVANTAGES:
- High performance
- Easy to implement
- Highly efficient (no parity overhead)
- No redundancy
- Limited business use cases due to no fault tolerance
ADVANTAGES:
- Fault-tolerant
- Easy to recover data in case of drive failure
- Easy to implement
- Highly inefficient (100% parity overhead)
- Not scalable (becomes very costly as the number of disks increases)
ADVANTAGES:
- Fault-tolerant
- High efficiency
- Disk failure has a medium impact on throughput
- Complex controller design
ADVANTAGES:
- Fault-tolerant with increased redundancy.
- High efficiency
- Remains a great option in multi-user environments that are not write-performance sensitive
- Write performance penalty vs 5
- More expensive than 5
- Disk failure has a medium impact on throughput
- Complex controller design
ADVANTAGES:
- Fault tolerance
- High Performance
- Expensive
- High Overhead
- Very limited scalability
ADVANTAGES:
- Higher fault tolerance, better performance, and higher efficiency than RAID 5
- Very Expensive
- Limited Scalability
ADVANTAGES:
- Higher fault tolerance than RAID 6
- Higher performance than RAID 6
- Higher efficiency than RAID 6
- Very Expensive
- Very complex/difficult to implement
