Finding the Ideal RAID Configuration: Target Capacity Calculator

The RAID Recommendation Calculator is the essential tool for transforming a storage goal (e.g., 80 TB of usable capacity) into a concrete hardware solution.

Forget trial and error. This tool instantly analyzes the trade-offs between all RAID levels (from RAID 5 to RAIDZ3) and tells you exactly how many disks you need to reach or exceed your desired net capacity, taking into account the size of your disks.

How to Optimize Your Purchase?

• Capacity versus Tolerance: See clearly how the choice of a level (RAID 6 or RAID 10) impacts capacity efficiency and fault tolerance.
• Minimum Purchase: Determine the minimum number of disks required. Avoid over-purchasing expensive equipment.
• Instant Comparison: The tool generates a detailed comparison table of the best options, showing you the configuration that offers the best efficiency (percentage of usable capacity) for your purpose.

Enter the usable capacity you need and the size of the disks you plan to buy, and our calculator will give you the most economical and reliable roadmap for your storage infrastructure.

How to Choose the Right RAID Level? Selecting a RAID configuration is a balance between three pillars: Performance, Capacity, and Redundancy.

• If you need maximum speed and don’t care about data loss: RAID 0.

• If you need maximum safety for critical data: RAID 1 or RAID 6.

• If you want the best balance for a home NAS: RAID 5 or RAIDZ1. Our RAID Recommender takes the guesswork out of the process by asking you the right questions about your hardware and goals.

If you choose a RAID level with high write overhead, make sure to check your SSD endurance.
