DiskMark review
A free, configurable Windows disk benchmark with 32-bit and 64-bit executables.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DiskMark is a small utility from NetworkDLS for benchmarking disks and hard drives on Windows. It is aimed at users who want a free, open-source way to assess drive performance and typical operating behavior without moving beyond a focused desktop utility. The vendor provides separate 32-bit and 64-bit Windows executables, while the source code is published under the MIT License through a linked GitHub repository.
Its main strength is configurable benchmark options within a narrow disk-performance scope. That gives users room to adjust the benchmark rather than relying only on a fixed run, while keeping the product centered on drive assessment. The published plans show a free open-source model, so there is no paid tier to compare or upgrade path to evaluate. The Windows-only platform fit is straightforward: users on supported Windows systems can choose the executable that matches their environment.
DiskMark is a suitable pick for users who value a compact, open-source Windows benchmark and want access to the source code. It is less suitable for teams seeking a broader platform ecosystem, AI-assisted analysis, or a current product with a wider set of documented capabilities. The published release information identifies version 1.0.0.8, released in February 2018, which may matter to buyers prioritizing a newer release cadence. Choose DiskMark when free licensing, Windows executables, and configurable disk benchmarking are the priority; consider an alternative when platform breadth or additional analysis features matter more.
