interpreting Storage Group stats.

Greetings,

            I want to understand the kind of high level conclusions we can get from below graph.

Y- Axis is IO rate as per the tool.

The easy one is , there are no sequential writes.

Can I conclude that read miss is slightly  higher than read hit, the workload is ~60% random and ~40% sequential?

I think the main question I have what is the core idea to have these particular parameters in 1 graph.

Thank you,

Neoseer.
