Iops and latency
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. RAID 6 needs six write I/Os for every application-level write request. So with 450 IOPS total, divided by 6, we only have single-disk performance of 75 IOPS.
