How to distinguish between random & sequential IO

Hello community.

I would like to know if & how I can distinguish between Average random IO & Average sequential IO.

In Live optics at the performance TAB when opening the project details & more information the tool is referring only to the Average read & write IO\Block size.

in the power store configurator, there is an option to be more accurate & set it to read write block\size  random & sequential.

Thank you in advance
