With the number of drives available now and the amount of drive types, it’s hard to say which disk setup is optimal for you. Our RAID calculator is a great way to determine the size and amount of disks. Here we’ll talk through some of the pros and cons of some of the RAID modes.

RAID 0:

ADVANTAGES:

  • High performance
  • Easy to implement
  • Highly efficient (no parity overhead)

DISADVANTAGES:

  • No redundancy
  • Limited business use cases due to no fault tolerance

RAID 1: 

ADVANTAGES:

  • Fault-tolerant
  • Easy to recover data in case of drive failure
  • Easy to implement

DISADVANTAGES:

  • Highly inefficient (100% parity overhead)
  • Not scalable (becomes very costly as the number of disks increases)

RAID 5:

ADVANTAGES:

  • Fault-tolerant
  • High efficiency

DISADVANTAGES:

  • Disk failure has a medium impact on throughput
  • Complex controller design

RAID 6:

ADVANTAGES:

  • Fault-tolerant with increased redundancy.
  • High efficiency
  • Remains a great option in multi-user environments that are not write performance sensitive

DISADVANTAGES:

  • Write performance penalty vs 5
  • More expensive than 5
  • Disk failure has a medium impact on throughput
  • Complex controller design

RAID 1+0:

ADVANTAGES:

  • Fault tolerance
  • High Performance

DISADVANTAGES:

  • Expensive
  • High Overhead
  • Very limited scalability

RAID 5+0:

ADVANTAGES:

  • Higher fault tolerance, better performance, and higher efficiency than RAID 5

DISADVANTAGES:

  • Very Expensive
  • Limited Scalability 

RAID 6+0:

ADVANTAGES:

  • Higher fault tolerance than RAID 6
  • Higher performance than RAID 6
  • Higher efficiency than RAID 6

DISADVANTAGES:

  • Very Expensive
  • Very complex/difficult to implement
