IOPS
Updated: 12/31/2022 by Computer Hope
The term IOPS (pronounced eye-ops), an abbreviation for input/output operations per second, is a performance benchmark used to measure the speed and efficiency of storage devices. This benchmark is commonly used on hard disk drives, solid-state drives, and storage area networks. Examples of software that measure IOPS include the applications Iometer, IOzone, and FIO (Flexible I/O Tester).
How does it work?
While being benchmarked, the storage device is tested for sequential access (read/write data at consecutive locations) and random access (read/write at scattered locations). The average of these results is the total IOPS for the device.
