Disk benchmarks let you examine storage performance through tests and measurements suited to the workload you care about. Compare sequential tests with random I/O tests, and check for IOPS and latency measurement to understand which aspects of performance each tool covers. Supported platforms may narrow the fit for your system, while a command-line interface can matter for terminal-based or scripted work. The leading entries are fio, Filebench, and DiskSpd, followed by Modern FS Benchmark, KDiskMark, Storage Benchmark Kit, D-Bench, and Parkdale. Free-plan availability and paid-from pricing are also listed, so consider those alongside the tests and metrics you need.
