Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Tests redundancy, snapshots, compression, rebuilds, and recovery
  • Measures random and sequential I/O, IOPS, latency, and tail behavior
  • Runs in GitHub Actions or on real hardware with JSON and dashboards
  • 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
  • Linux-only platform support
  • Requires filesystem and hardware benchmarking expertise
  • Focused on filesystem evaluation rather than general disk testing
  • 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

Modern FS Benchmark is an open-source Linux benchmark suite for comparing copy-on-write and classic filesystem stacks. It is designed for engineers evaluating btrfs, ZFS, bcachefs, ext4, and XFS across single-device, redundant, encrypted,…
