ZFS & Raid Calculator
Erasure coding Calculator
RAID & ZFS Calculator
This RAID performance calculator and TCO analysis created to optimize your storage infrastructure. Get accurate estimates and recommendations based on real-world business scenarios..
Why use our calculator ?
Professional precision
Our algorithms incorporate real-world write penalties, controller overhead, and system limitations to deliver results that are close to real-world performance.
Conservative approach
Unlike optimistic calculators, we apply reduction factors based on company experience to avoid unpleasant surprises.
Economic analysis
Calculate the total cost of ownership (TCO) over 5 years, including purchase, electricity, maintenance, and component replacement.
Supported data
Complete calculator for all your storage needs
Advanced Features
Configuration flexible
Adjust the number of disks per RAID group, multiple groups, and read/write ratios as needed.
Support RAID & ZFS
All classic RAID levels (0, 1, 5, 6, 10) plus ZFS variants (RAIDZ1, RAIDZ2, RAIDZ3) with their specificities.
Smart validation
The calculator automatically checks the validity of the configurations and warns you of impossible configurations.
Interface responsive
Usable on desktop, tablet and mobile with an intuitive interface and clear visualizations.
Real-time calculations
Instant results when editing with separate display of read and write performance.
Business scenarios
Pre-configured settings for different use cases: office automation, virtualization, databases, archiving.
⚠️ Important to remember
This calculator provides estimates based on typical configurations and conservative factors. Actual performance may vary depending on :
- The model and specifications of hard drives
- The RAID controller used (hardware vs. software)
- System configuration (CPU, RAM, data bus)
- The type of workload and access patterns
- Firmware and file system configuration
Recommandation : Use these results as a basis for planning, then perform tests with your specific hardware to validate real-world performance..
Typical use cases
