IOPS Calculator
The IOPS Calculator helps you estimate storage performance requirements based on workload inputs. Enter your read/write mix, average block size, and target IOPS to calculate front-end and back-end performance metrics. The tool applies write penalty multipliers for common data protection schemes including RAID 1, 5, 6, 10, and erasure coding profiles, showing both front-end IOPS and the actual back-end IOPS your storage subsystem must sustain. Results include read and write throughput estimates in MB/s and a guidance panel interpreting your workload profile. Presets for common scenarios — general VM clusters, SQL databases, VDI, backup repositories, and file servers — let you quickly model typical enterprise workloads. Ideal for storage sizing conversations, vendor evaluations, and infrastructure planning. All calculations run locally in your browser.
