WebIOPS represents how quickly a given storage device or medium can read and write commands in every second. The “back end” IOPS relates to the physical constraints of the media itself, and equals 1000 milliseconds / (Average Seek Time + Average Latency), with the latter two also measured in milliseconds. Web1 jan. 2013 · This is still ok, but notice the latency: it is clearly around 40 milliseconds, whereas 20 milliseconds is the rule of thumb where performance will start to significantly degrade.
