Hey, thank you, you have just corrected a massive misconception I had about SSD performance.
My logic always worked like this: if IOPS is input / output per second, surely that means 10,000 IOPS of, say, the usual random 4kb file write at QD1, then that means I can get 10,000 of those in one second. So, a higher number must be better.
I had no idea that IOPS needs to take latency into account. After having done some reading I am still somewhat confused as to how this really works, but for future reference I will use latency as a measurement of performance again, as that is indeed what I thought IOPS was.
