Blackmagic design speed test8/14/2023 ![]() ![]() NOTE: As part of my Thunderblade review, I ran twelve speed tests on each software and got very similar results. I ran four tests using each software to measure the read and write speeds of the Thunderblade. I created a RAID 0 using an 8 TB OWC Thunderblade SSD, which uses four NVMe SSDs. ![]() Clearly, one – or both- of these software tools is wildly wrong. Some variation during tests is expected, but this amount of difference is ridiculous. There is a 40% difference when measuring write speeds and a 22% difference when measuring read speeds between these two software tools. Since we use both these tools daily to measure and verify the performance of our system, these differences trouble me - a lot. Except, I get significantly different results when testing storage speeds using AJA System Test Light versus Blackmagic Disk Speed Test. (Read that review here.) This hardware speed demon is designed to maximize data transfer speeds using Thunderbolt 3 or 4. This last week, I was testing the speed and capacity of the new OWC Thunderblade SSD RAID. By the way, thanks for all your work testing and documenting the test results, very much appreciated.” I don’t have any information on why there is a discrepancy between the full AJA system test and BMD, however I will let you know as soon as I have update from Product Development. Today their tech support emailed me: “I did forward your test results to Product Development for review and they did acknowledge the Lite version has an issue. (Errors also exist in Apple Activity Monitor.) Assume whatever test results you are looking at are wrong. So far, no developer is able to explain these differences. Here’s an updated article looking at the differences between measurement tools. As always, I’ll keep you posted as soon as I hear back from them.” Since then, I’ve heard nothing.

Yes, Blackmagic Disk Speed Test is a completely safe tool. Before you start using this software, you may want to consider reading the Blackmagic Privacy Policy to see how and why the software collects your personal information.Update – Nov. Is it free?Īlthough Blackmagic Disk Speed Test is a high-quality software, it is surprisingly offered to download completely free of charge. Disk Speed Test will continue to test writes and reads from your disk, so you can evaluate both performance and readability over time. ![]() Simply click on the start button, and Disk Speed Test will perform a writing test on your disk using large blocks of data and then display the result. The application works identically to the Mac version.
