Definition: What Is IOPS?
IOPS (Input/Output Operations Per Second) is a measure of how many read and write operations a storage device can perform in a second. It is commonly used to determine the performance of storage devices such as hard disk drives (HDDs), solid-state drives (SSDs), and storage area networks (SANs). Higher IOPS values typically indicate better storage performance and faster data access. However, IOPS can vary depending on factors such as the type of storage device, workload, block size, and queue depth. Therefore, it is important to consider these factors when measuring IOPS to ensure that the workload used is representative of the expected usage scenario.
