What Is Input Output Operations Per Second Iops

What Does Input/Output Operations per Second (IOPS) Mean?

Input/output operations per second (IOPS) is the measure of how many input/output operations a storage device can complete within one second. It is a standard performance benchmark for hard drives, solid state drives, flash drives and even network attached storage (NAS) devices. Although IOPS is a common performance indicator, performance measures for the same device can vary from system to system based on other factors.

Techopedia Explains Input/Output Operations per Second (IOPS)

• Sequential Write IOPS: The average of the number of sequential write I/O operations that occur per second
• Sequential Read IOPS: The average of the number of sequential read I/O operations that occur per second
• Random Write IOPS: The average of the number of random write I/O operations that occur per second
• Random Read IOPS: The average of the number of random read I/O operations that occur per second
• Total IOPS: The total IOPS when performing mixed read and write operations
