Visualizing Usage Changes

vtView will help you visualize effects of application software changes on system performance and endurance.

In the image below, vtView shows usage changes from aggressive to gentle.

— Indexes 0 to 3 show usage acceleration as aggressive. Estimate remaining TBW is 101.3 TB

— Indexes 4 to 10 show new usage on the StorFly and Life Acceleration is slow. Estimate remaining TBW is 209.78 TB. The new usage change improves the SSD life.

Regression Testing

Run vtView with your software change as part of your regression testing workflow to ensure your SSD’s endurance still meets requirements.

How data is written to the SSD determines its endurance.

vtView shows you how much data is written or read, and when and how read-write pattern affects the endurance. vtView helps organize the data, putting read, write, temperature, and other essential data together. Users can see how read-write patterns change when there is change in the system.

The user can see how these change affect the SSD temperature which in-turn affects SSD data retention. When the SSD is getting close to end of life, data retention ranges from a few days to a few months.

Temperature Characterization Mode

Run vtView in Temperature Characterization Mode to collect temperatures and other SSD information. vtView Data is organized neatly and ready for analyzing by vtView or Excel.

Compare SSD

If multiple SSD are tested together in the same system, vtView has a table that you can look at them together and compare. See the overview for the differences between capacities, between firmware, or between models.

Visualize Workload Changes

The video on the right shows how to visualize workload changes from sequential writes to random writes.

In a real system, a software designer can run a life acceleration test and quickly find out how changes affect the SSD’s endurance. Or when a new software is installed in the system, vtView provides a visualization of change in life acceleration.
