low QD IOMeter synthetic tests

Recommended Posts

In SR reviews, a standard feature is the IOMeter synthetic tests: database, file server, web server, and workstation.

This is useful data, but for many users, the most important part is the low QD portion, basically QD=1 and 2. Most users will very seldom have their SSDs reach QD > 4.

But it is difficult to compare SSDs at QD=1 and QD=2 in these graphs because they tend to overlap each other since the scale of the graph is much larger to encompass the QD=32 results.

It would be nice if you could present the data in such a way that the QD=1 and QD=2 results are easier to compare among SSDs. Possibly it could be done by changing the y-axis to a log scale, but I'm afraid that still might not be enough to see the low QD results clearly. Perhaps the best thing would be to add an additional graph for each of the four tests that shows only QD=1 and 2, with the vertical scale enlarged to show detail at the low QDs.

As mentioned in this news piece briefly:

we are going to be restructuring the way we present performance benchmarks and going into areas that will better address some of your concerns.
