Jazz Disk Bench Lite

Jazz Disk Bench is an application for accurately measuring performance of the storage. Both sequential and random read write is supported. It also support 2-100GB stress test and external storage test(Pro version).

BenchMark Description:
1. Sequential Test. Reading or writing 16MB data sequentially. Reflect the speed when copy large files.
2. Random Test. Reading or writing 4 KB blocks in a random location. Random IO play an important role in performance of your device. The slower random performance, the more possibility of lag.
3. Stress Test. Writing large data(2-100GB, depends on the setting) sequentially to storage. Can test the stability of storage, and measure the native speed of disk when cache is used up.

Note:
When test external storage, please make sure the storage is writable and connection cable is stable.
