RAID 50 vs RAID 60
Table of Contents

In the world of data storage and protection, RAID configurations are a vital element, ensuring data integrity and availability. When tasked with selecting the ideal RAID level for your organisation, you’re often presented with various options, each with its unique strengths and weaknesses.

Among these choices, RAID 50 and RAID 60 are two frequently implemented configurations. In this comprehensive guide, we will delve into the nuances, advantages, and drawbacks of RAID 50 and RAID 60 to empower you with the knowledge to make an informed decision.

What are RAID 50 and RAID 60?

Before delving into an in-depth comparison, let’s establish a clear understanding of RAID 50 and RAID 60, grounding ourselves in the fundamentals of these two RAID configurations.


RAID 50, often referred to as “striping with distributed parity,” is essentially a combination of two RAID levels: RAID 5 and RAID 0. Its core purpose is to strike a balance between data redundancy and performance.

Within a RAID 50 array, data is striped across multiple RAID 5 arrays. Each RAID 5 array consists of multiple drives, and the data is distributed across these arrays. Moreover, RAID 50 incorporates parity data, which is meticulously distributed across the drives to provide redundancy and fault tolerance.

RAID 50 Data Recovery

Advantages of RAID 50

  • Performance: RAID 50 stands out for its exceptional read and write performance compared to RAID 5. This performance boost is primarily attributable to the data striping across multiple RAID 5 arrays.
  • Redundancy: Despite its performance prowess, RAID 50 does not compromise on redundancy. It ensures data security through distributed parity, meaning that if a single drive fails within one of the RAID 5 arrays, data can still be reconstructed using the parity information.
  • Capacity: RAID 50 can accommodate larger storage configurations since it amalgamates multiple RAID 5 arrays.


In contrast, RAID 60 is an extension of RAID 6 and RAID 0, engineered to provide enhanced fault tolerance and performance while maintaining a fine balance between redundancy and capacity.

Within a RAID 60 array, data is striped across multiple RAID 6 arrays. Each of these RAID 6 arrays includes two parity blocks, providing dual redundancy. Similar to RAID 50, RAID 60 employs striping to enhance performance.

Advantages of RAID 60

  • Redundancy: The standout feature of RAID 60 is its remarkable fault tolerance. It achieves this through the inclusion of dual parity blocks within each RAID 6 array. Consequently, RAID 60 can endure the failure of up to two drives within a single RAID 6 array without incurring data loss, a feat that RAID 50 cannot match.
  • Performance: While not as fast as RAID 50, RAID 60 offers commendable performance, particularly for read-intensive tasks.
  • Data Integrity: RAID 60 is designed to maintain data integrity even in the face of multiple drive failures, making it eminently suitable for critical applications.

Comparing RAID 50 vs RAID 60

Now that we have gained a foundational understanding of RAID 50 and RAID 60, let us embark on a comprehensive comparison, evaluating them across various critical aspects to facilitate your selection process.

Fault Tolerance

Both RAID 50 and RAID 60 integrate parity data to deliver fault tolerance. However, RAID 60 takes the lead in this department, offering superior fault tolerance because of its dual parity blocks within each RAID 6 array. This means RAID 60 can withstand the failure of up to two drives in a single RAID 6 array without data loss, while RAID 50 can only tolerate the failure of a single drive within a RAID 5 array.


Regarding performance, RAID 50 generally outpaces RAID 60 across most workloads. The secret to RAID 50’s success lies in the striping of data across multiple RAID 5 arrays. That being said, RAID 60 isn’t far behind and offers commendable performance, particularly for tasks demanding intensive data reads.


RAID 50 has the upper hand in terms of storage capacity. As it amalgamates multiple RAID 5 arrays, it can offer a more extensive overall storage capacity compared to RAID 60. If maximising storage space is your chief objective, RAID 50 may emerge as the more suitable option.

Data Rebuild Time

In the unfortunate event of drive failure, RAID 50 and RAID 60 necessitate a rebuild process to reinstate data redundancy. Typically, RAID 50 enjoys a shorter rebuild time, primarily because of its involvement with smaller RAID 5 arrays. On the other hand, RAID 60’s rebuild time can be more protracted, owing to the larger RAID 6 arrays and the necessity to compute dual parity blocks.


Use Cases

  • RAID 50: This configuration is exceptionally well-suited for environments requiring a harmonious blend of performance and redundancy. It finds common usage in file servers, database servers, and virtualisation environments.
  • RAID 60: RAID 60 shines in environments where data integrity and elevated fault tolerance are imperative. It’s an ideal choice for large-scale enterprise storage systems, online transaction processing (OLTP) databases, and archival systems.

Choosing the Right RAID Level for Your Needs: RAID 60 vs RAID 50

Ultimately, the selection between RAID 50 and RAID 60 hinges on your specific requirements and priorities. To aid you in your decision-making process, here are some key considerations:

  • Data Criticality: If your data is of paramount importance and any form of downtime or data loss is unacceptable, RAID 60, with its heightened fault tolerance, stands as the safer choice.
  • Performance vs Redundancy: If performance takes precedence over redundancy, provided you have robust backup solutions in place, RAID 50 may emerge as the more suitable option.
  • Budget: RAID 50 tends to be more cost-effective, as it necessitates fewer drives for the same storage capacity in comparison to RAID 60.
  • Scalability: It is essential to contemplate your future scalability requirements. RAID 50 offers a more flexible scalability path because of its reliance on smaller arrays, whereas RAID 60 may demand the addition of more drives at once because of its employment of larger arrays.

Data Recovery Considerations for RAID 60 vs RAID 50

At PITS, we recognise that despite the implementation of robust RAID configurations and meticulous precautions, data loss can still transpire because of a myriad of factors, including hardware malfunctions, human errors, or software glitches. In the realms of both RAID 50 and RAID 60, data recovery can be intricate.
