Built to make storage performance understandable
About Jazz Disk Bench
Jazz Disk Bench is a cross-platform application by Chang Studio for measuring storage performance on iOS, Android, Windows and macOS.
Test, explore, compare
The app measures sequential and random read/write performance, supports sustained-write stress testing, and can test supported external or custom storage locations. The website brings together contributed internal-storage results, grouped by the same Model labels used in the app.
Use Rankings to discover results, a Model page to explore its capacities, and Compare to inspect two complete configurations.
About the results
Public results are community-contributed measurements. Speeds are aggregated by Model, capacity and platform. Each configuration displays its sample count and latest measurement date. See the methodology for test definitions, units and contribution rules.
