Our review
Pros	Tests sequential, random, read, write, and mixed performance. Shows MB/s, GB/s, IOPS, and average latency results. Exports results as text or PNG, JPEG, and BMP images.	Defines custom workloads with its Workload Model Language Reports per-operation throughput, IOPS, latency, and histograms Supports random, sequential, direct, and synchronous-write testing
Cons	Windows-only software. The Microsoft Store edition costs $9.99 one-time. Its many settings may be more than casual users need.	Command-line execution requires locally compiled and installed software Workload modeling requires defining filesets, processes, threads, and flowops Directory platform coverage is limited to Linux
Our verdict	CrystalDiskMark is an open-source Windows storage benchmark for measuring sequential, random, read, write, and mixed disk performance. It suits users comparing SSDs, checking drive behavior, or documenting storage results. You choose the… Read the review →	Filebench is an open-source, command-line benchmark for file systems and storage devices. It is designed for engineers and performance teams that need to model application-style I/O rather than run only fixed disk tests. Its Workload Model… Read the review →
