hIOmon SSD Performance Monitor - Understanding desktop usage patterns.

[Computurd]

I did come to the conclusion that the QD are 'per process' by loading iometer, and setting a 4k random file to read at 64QD, while also loading other programs, i ran a test
the other programs only showed their own respective QD values in the monitoring. the dynamo.exe (iometer) however showed its own individual qd of 64 , of course.

The main thrust of our testing here is to find out the value of SSD in raid, and its impact upon the actual use of an moderate to heavy user.
There are two basic schools of thought here, the first being that an individual SSD is fast enough that it can handle even heavy use identically to a SSD raid array.
Or, even as an extension of that, that a SSD with a lower random performance at high QD random will perform essentially the same as some of the newer, faster SSD that have much faster high QD performance.

Tools used to measure the QD of a system that we have explored using usually rotate around average QD.
however, even using the windows built in performance monitoring counters you can see there are big QD spikes in heavy usage, but that they are resolved quicker with faster devices/arrays.
since these spikes are resolved quickly, the average QD does little to quantify how high we are hitting.
but the real question arises that we know the average desktop performance rarely goes above 4-6, but I am trying to see how high it spikes, and how fast those spikes are resolved, to compare a single SSD v. an SSD array that can do 160,000 IOPS @ 4k random.

is there a way to show the maximum QD for the individual device?

EDIT: yeah now i see it.
