App Description
Professional phone storage speed test & benchmark for internal & external drives
Jazz Disk Bench: Pro Storage Benchmark
Accurately measure the performance of your phone's internal storage (UFS/EMMC), SD cards, and external drives. Compare results across platforms with our consistent testing engine.
Key Features:
* Precise Testing: Sequential and 4K Random read/write speeds.
* Stress Test: 2GB–100GB tests to evaluate sustained NAND speed and SLC cache.
* Cross-Platform: Industry-standard methods for comparable scores.
* External Support: Test USB drives and SD cards via custom folder selection.
* Zero Bloat: No ads, no bloat, no unnecessary permissions.
Benchmark Modes:
1. Sequential: Measures peak speed for large file transfers (movies/games).
2. 4K Random: Measures IOPS and responsiveness. Low random speed is the primary cause of system lag.
3. Stress Test: Evaluates stability and thermal throttling during long-duration write tasks.
Note: Ensure a stable connection for external storage tests.
