IOPS Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Required IOPS = (read ops/sec + write ops/sec) * peak multiplier. Throughput MB/sec = (read ops * read KB + write ops * write KB) / 1024 * peak multiplier.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Read Ops: 2,000 ops/sec
- Write Ops: 500 ops/sec
- Average Read Size: 16 KB
- Average Write Size: 16 KB
- Peak Multiplier: 1.5 x
Expected outputs
- Required IOPS: 3,750
- Throughput: 58.59 MB/s
- Read Mix: 80.00%
- Daily IO Count: 216,000,000
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Read/write rates are steady-state averages.
- Latency is not predicted from hardware behavior.
- No workload telemetry is stored.
Unit handling
- Read Ops accepts values in ops/sec.
- Write Ops accepts values in ops/sec.
- Average Read Size accepts values in KB.
- Average Write Size accepts values in KB.
- Peak Multiplier accepts values in x.
- Throughput is displayed in MB/s.
- Read Mix is displayed as a percentage.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Percent outputs are displayed with two decimal places.
- Input precision follows configured step values where provided.
