Disk Bench review
A free Windows tool for timing file copies, reads, and test-file creation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Disk Bench is a free Windows utility from Nodesoft for measuring file-system performance through timed file operations. It suits users who want a straightforward way to compare file and directory transfers, read one or more files, or create test files using configurable blocks. The tool works with the current filesystem rather than synthetic tests, making it relevant to basic real-world file-copy benchmarking.
Its strongest area is practical file-operation coverage. Disk Bench can copy a file between locations and time the operation, copy complete directories while logging the result, and perform reads, including parallel reads. It can also retain destination files after a test, which is useful when the resulting files need to remain available for inspection or follow-up work. Command-line switches support benchmark execution outside the main interactive workflow, while log files provide a record of results.
The Free plan includes file copy, read, and creation benchmarks alongside command-line operation. Disk Bench runs on Windows and requires Microsoft .NET Framework; Nodesoft states that its programs are tested on Windows 10 and 11. Its focus is narrower than tools built around a wider set of disk measurements: the documented workflow centers on file transfers, reads, directory copies, and test-file creation rather than a broad metrics suite. Choose Disk Bench for free, scriptable Windows file-operation benchmarks. Choose an alternative if your evaluation depends on a wider range of specialized disk measurements or cross-platform support.
