Input/Output Operations per Second (IOPS) measures the performance of a storage device or system, typically expressed as the number of reads and write operations that can be performed per second. IOPS is an important metric for determining the overall performance of storage systems, especially in high-performance computing and enterprise environments where large amounts of data need to be accessed and processed quickly.
The Input/Output Operations per Second (IOPS) value of a storage device or system can be affected by various factors, such as the type of storage device (e.g., hard disk drive (HDD), solid-state drive (SSD)), the type of interface (e.g., SATA, SAS, NVMe), the size of the data block, and the type of workload (e.g., random or sequential access).
For example, a hard disk drive typically has a lower Input/Output Operations per Second (IOPS) value than a solid-state drive because of its mechanical nature. Still, hard disk drives are more economical and have a larger storage capacity. Solid-state drives, on the other hand, have a higher IOPS value but are more expensive and have a smaller storage capacity.
