Crystal DiskMark's sequential-read tests measure read/write activity with data written in a large contiguous block on the drive, which is similar to how manufacturers themselves test drives to advertise their performance. We also use the Crystal DiskMark utility for a second opinion on throughput. These scores are useful in discovering the theoretical maximum speed that a drive can achieve. ![]() But it also returns some useful throughput measurements.īlackMagic offers both a read score and a write score, which we also compare with those of other, similar drives. This utility is typically used to discern whether a given drive has enough throughput to play back specific video formats smoothly. We use the macOS-only BlackMagic Disk Speed Test app from professional media software firm DaVinci to perform this test. Our next test measures a drive's throughput in bits per second. The score is only meaningful relative to other scores. We mention this score in each review and compare it with the scores that other, competing drives received. The PCMark 7 Secondary Storage test results in a proprietary score that is usually in the thousands. These simulated workloads include a Windows Defender virus scan, an image-import task, a video-editing session, and application launches. The Secondary Storage test is trace-based, which means it measures how quickly software commands are performed during everyday workloads to which you might subject your PC. The company's benchmarking apps are used not only by publications like PCMag, but also by drive and PC manufacturers themselves. Our most wide-ranging benchmark is the PCMark 7 Secondary Storage test. We also test on a 2016 MacBook Pro, using the Type-C/Thunderbolt 3 ports, for certain of our tests. There are still different tests and benchmarks for the speed of compilation and assembly in different projects by different compilers and different IDEs, or for example, the speed of encoding or transcoding video into different formats, but these, in my opinion, are already highly specialized tests for a separate topic.We test external drives using an Intel X299-based testbed equipped with all the trimmings, including a USB 3.1 Gen 2 USB Type-C port. ![]() Tables with the results of different tests in different Macs: Interesting articles and pages about the topic: ![]() (it seems to just heavily load the processor) Intel® Math Kernel Library (Intel® MKL) Benchmarks Metal Particles (as demo /bench) new Nbody-Metal (demo/bench)ġ5. I remind you that the results should be the most reliable, before starting the benchmark test, it is advisable to terminate all unnecessary programs, for example by clicking on them in the Dock and selecting "Finish", and it is better to restart the computer altogether and wait 5 minutes until it finishes background startup processes after startup and then start testing.ġ4. I suggest posting here a list of benchmark programs with which you can measure the power of computers with macOS or, for example, compare the performance of macOS and Windows or different versions of macOS if several different operating systems are installed on your computer.Īs well as a list of programs with which you can track all possible indicators of your computer's components - processor, graphics card, HDD, SSD, coolers, and so on - will be in a separate topic.Īlso share your results or links to the results in the test run in these synthetic tests.
