USB 2.0 – 480 megabits / s – 60 megabytes / second.These theoretical read rates translate into: Below are the theoretical speeds for USB 2.0, 3.0 and 3.1: You might have bought a USB 3 thumb drive (or a certain USB port) that doesn’t appear to be as fast as others and this will help you verify your suspicions.įirst up, what are you supposed to be getting as a result? Well, these vary a lot more than what you might expect. Blackmagic RAW Speed Test is currently available for Mac as a free download from the Blackmagic Design website.There are various method and utilities to test how fast are your external (and internal) drives really working. The benchmarking tool is useful if your workflow includes Blackmagic RAW files. “So we thought using Blackmagic RAW decode speeds would be a good estimate of real world computing performance because it’s doing the exact same processing the computer is doing while editing, color correcting and doing visual effects rendering.” “We felt that computer performance measurement tools did not really perform the types of testing we needed in the film and television industry, because they operate very differently to the kinds of processing we do,” said Grant Petty, Blackmagic Design CEO. Results are displayed in an easy to read table that shows users how many frames per second their computer can decode for all supported resolutions. Simply select Blackmagic RAW constant bitrate 3:1, 5:1, 8:1 or 12:1 and the desired resolution to perform the test.Īlthough the benchmarking tool will run multiple resolution and frame rate tests on their system, users can also select a specific test resolution to run on the main meters and the test will continue to run constantly, allowing stress testing of host computers, says Blackmagic Design. Multiple CPU cores and GPUs are automatically detected and used during the test so that you get accurate and realistic results. Blackmagic RAW Speed Test is a new CPU and GPU benchmarking tool that you can use to test the speed of decoding full resolution Blackmagic RAW frames on your system. Now you can test your system’s CPU and GPU performance for working with full resolution Blackmagic RAW video.
