Instead of fio
fio alternatives
fio is aimed at people who need to shape I/O tests around a particular performance question or bug. Job files and command-line parameters let it configure patterns, block and I/O sizes, engines, queue depth, targets, and threads or processes. It can measure random and sequential I/O, report IOPS and latency, and return results in several formats. Client/server mode can send jobs to remote hosts, while its HTTP engine supports HTTP and S3 access. It is free and runs on Linux, macOS, and Windows.

That breadth comes with a job-based, command-line approach, which may be more setup than a focused drive benchmark calls for. The alternatives differ in test scope, output, and access method: some offer graphical tools, drive-specific access modes, charts, or storage-backend integrations, while others have narrower platform support or fewer workload controls. When switching, weigh the storage targets and metrics you need, whether you want to define workloads or run simpler checks, and whether remote execution or a particular operating system is essential.
