Are your disks working optimally? Can they cope with high–resolution video? If you’re an editor and you need to check your equipment — or if you want to assess your drive speed’s read and write performance for any reason whatsoever — the Blackmagic Disk Speed Test is for you. Available for free from the Mac App Store, you just click the Start button and Disk Speed Test runs read and write tests on your disk using large blocks of data, then displays the results. You can test your local drive or connected disks, and screenshot the data for future reference. It helpfully cleans up after itself too, so there’s no junk left behind after the tests.
