Step 2: Select the All button to perform all tests or select the corresponding buttons (Seq, 512K, 4K, 4K QD32) to test each specific test on the reading and writing speed.

- Seq (Sequential) : Performs sequential read and write speed (Block Size = 1024KB).

- 512K (Ranrom 512K) : Performs random read and write speed (Block Size = 512KB).

- 4K (Ranrom 4K, Queue Depth = 1) : Performs random read and write speed (Block Size = 4K).

- 4K QD32 (Ranrom 4K, Queue Depth = 32): Performs random read and write speed (Block Size = 4K, Queue Depth = 32).
