VSAN Hybrid vs All-Flash Stretched Cluster Testing

This post reorganize the results from the previous two posts to show comparison between Hybrid and All-Flash VSAN.

Conclusion:
In an All-Flash VSAN setup, the write speed perform better, be it the testing VM on the preferred or secondary site. The difference is about 3X.
The read latency is also much lesser in an All-Flash VSAN setup in both sites.

*The remarks in the AS SSD Benchmark tool are not accurate for the Hybrid VSAN as I did not change the description when the tool was running on the Secondary Site.
