Storage speed dictates how smoothly your computer handles heavy workflows. If you are a video editor, developer, or creative professional, knowing the exact read and write capabilities of your drive is essential. Blackmagic Disk Speed Test is the industry-standard tool used to benchmark storage performance on macOS.
If you are looking for a standalone to install on multiple machines without an Apple ID, it is often bundled with the Blackmagic Desktop Video software or DaVinci Resolve packages available on the official Blackmagic Design support page.
With high-resolution content creation becoming the norm, slow storage can create bottlenecks.
| Tool | Key Feature | Best For | | :--- | :--- | :--- | | | One-click sequential read/write testing, video format compatibility charts. | Video editors and creative pros who need a quick, visual benchmark. | | AJA System Test Lite | Tests read/write speeds and can also test for dropped frames with a custom stress test duration. | Professionals needing a more rigorous, customizable stress test for video capture and playback. Note: Some users report AJA's results are slower. | | AmorphousDiskMark | Tests sequential and random read/write speeds with various queue depths, similar to CrystalDiskMark on Windows. | Users wanting a more technical benchmark that provides a broader range of performance metrics than just sequential speeds. | | ATTO Disk Benchmark | Tests read/write speeds using different data block sizes, showing how performance varies from small to large files. | Users who want to see how their drive performs with both large video files and many smaller files. | | CrystalDiskMark | A highly popular and detailed benchmark for Windows. Some Mac alternatives exist, like KDiskMark. | PC users or Mac users seeking an open-source, comprehensive benchmark. It's not natively available on macOS. | blackmagic disk speed test mac download dmg
In this guide, we will walk you through how to , how to install it, and how to use it to evaluate your SSD or hard drive in 2026. What is Blackmagic Disk Speed Test?
Blackmagic Disk Speed Test requires:
Blackmagic Disk Speed Test is excellent for what it does, but it's not the only option. Its primary focus on for video files means it doesn't test random read/write performance, which is important for everyday tasks like launching apps or loading games. Here are a few powerful alternatives: Storage speed dictates how smoothly your computer handles
: Plug external drives directly into your Mac's ports rather than through unpowered USB hubs.
Before downloading the DMG, ensure your system meets the minimum criteria:
: Use the gear icon to select a dummy file size (1GB to 5GB). Larger sizes test sustained performance better. If you are looking for a standalone to
Download the ZIP, open the DMG inside, and run the installer.
It fills your drive with blocks of data and then measures the transfer speed. Simultaneously, it compares those speeds against a built-in checklist of standard video formats (like ProRes, H.265, and Cinema DNG) at various resolutions (1080p, 4K, 8K) and frame rates. This tells you instantly whether your storage is a bottleneck for your editing timeline. Blackmagic Disk Speed Test Mac Download: App Store vs. .dmg
Examples
You can test the Helmholtz assumption that the relative phases of the overtones are irrelevant to hearing.
In analyser experiments you capture sound from the sound card or from a WAV file up to several seconds long, select the starting time of the time slice and analyse time and frequency responses. The example shows the spectrum of a piano playing a middle C (262 Hz). The non-harmonic overtones are clearly seen. (Due to the stiffness of the string, the frequencies of the partials are too high.)
