Web10 apr. 2024 · IOPS is a standard performance benchmark for any storage device, including hard drives (both HDD and SSD), flash drives, and network attached storage (NAS) devices. IOPS is a critical metric for storage devices because it directly frames the device’s ability to handle requests from applications and users. Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage … Meer weergeven To meaningfully describe the performance characteristics of any storage device, it is necessary to specify a minimum of three metrics simultaneously: IOPS, response time, and (application) workload.
