IOPS

Sam ChenFebruary 8, 2017

IOPS, or Input/Output Operations per Second, is a storage performance metric which measures how many reads and writes are occurring every second. As smaller files take less time to transfer compared to larger files, the IOPS metric is typically used to measure transfers of 4K or 8K file sizes. Larger filesize reads and writes such as 128K, 512K and larger are typically measured by throughput such as MB/s (Megabytes Per Second) or GB/s (Gigabytes Per Second).
