Blackmagic Disk Speed Test is excellent for its purpose and ease of use, but it's not the only option. Here's a quick comparison:

| Issue | Most Likely Cause and Solution | | :--- | :--- | | | You are trying to test the read-only system volume ( Macintosh HD ). Solution : In the target drive selector, choose the Macintosh HD - Data volume instead. | | App won't start | The app may require you to create a large disk image ( .dmg ) as a test target when it can't write to the selected drive. Solution : In Disk Utility, create a new blank disk image at least 7 GB in size. Then, select that disk image as the target in the app. | | Can't test my Mac's internal drive | This is a common misunderstanding. The app is designed to write data to a drive to test it. For the startup disk, follow the workaround above using a DMG image on the internal drive. | | M1/M2/M3 Macs show slower-than-expected results | Some users have noted this issue. Ensure you are testing a writable volume. For the most accurate test, use an external SSD or a large .dmg file as your target. | | App Crashes | Ensure your macOS is up to date. As a last resort, uninstall and reinstall the app from the Mac App Store. | | Can't select an external drive | Make sure the external drive is properly formatted (e.g., APFS, Mac OS Extended (Journaled)) for full read/write access. Drives formatted for Windows (exFAT/NTFS) may not work as reliably. |
