Iops formula

WebIOPS stands for input/output operations per second. It’s a measurement of performance for hard drives (HDDs or SSDs) and storage area networks. IOPS 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 ...
