Scorecard
Median of each storage measurement's primary metric; lower is better. Medians within 5% count as roughly even, and a storage measurement gets no speed verdict when either provider completed fewer than 50% of runs.

- One workload, every provider. The same script, payload, and model hit every provider, addressed the way its own API expects. Nobody gets a tuned or special path.
- Repeated on a schedule. Every suite runs many iterations per provider, automated on a recurring schedule, so results reflect steady state rather than one lucky request.
- Raw results published. Every run is committed as JSON to the public benchmarks repo, next to the code that produced it. Nothing is cherry-picked or held back.
- How this comparison is built. Each benchmark compares the two providers' medians; results within 5% count as roughly even. A comparison is published only when both providers completed the 10 MB storage lifecycle benchmark reliably: at least 50% success for each provider, in benchmark runs from the last 30 days.
