Blackmagic Disk Speed Test review
A focused storage benchmark for sustained reads, writes, arrays, and video throughput.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Blackmagic Disk Speed Test is a storage benchmark designed for video-production workflows. It measures disk write and read performance with large blocks of data, continuously testing both operations over time. Results are reported in video frames per second, giving users a workload-focused way to assess whether storage is suited to high-quality video. It supports macOS and Windows, with the Mac app offered as a free download and the Windows version included among the applications in Blackmagic Design’s Desktop Video package.
The utility’s main strength is its narrow focus. Rather than covering broad PC performance areas, it concentrates on sustained storage behavior, video-frame throughput, and disk-array performance. Large-block testing and continuous reads and writes fit workflows where storage performance needs to be considered over an ongoing video workload rather than through a brief, general-purpose score. That makes it a practical choice for users evaluating storage for video production, especially when disk arrays are part of the setup.
The trade-off is a limited documented feature set beyond the core test. Configuration, export, and comparison capabilities are limited, so users looking for a highly configurable benchmarking suite or detailed result-management workflow may need another tool. Blackmagic Disk Speed Test is best suited to video creators, storage evaluators, and teams that want a straightforward read/write benchmark tied to video throughput. It is less suitable for buyers seeking broad system benchmarking, extensive result analysis, or a wide range of configurable tests.
