IOPS

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.
