Disk benchmarks help you examine storage performance through specific tests and measurements. Compare sequential tests with random I/O tests, and check whether IOPS and latency measurement are available for the performance questions you have. Supported platforms can help narrow the choices for your system, while a command-line interface may suit terminal-based or scripted workflows. The ranking opens with fio, DiskSpd, and Filebench, followed by Modern FS Benchmark and Storage Benchmark Kit. Free-plan availability and paid-from pricing are also listed; weigh them alongside the supported tests and platforms that fit your work.
29 disk benchmark software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
