-w50 - Specifies the percentage of write and read requests. #Understanding blackmagic disk speed test results software#
-Sh - Disables software and hardware write caching.You can override this with the "-s" option. -b8k - Defines the size of the block (default is 64K).-o4 - Specifies the number of outstanding I/O requests per target per thread.
Usually, you can use one per available core in the processor.
-t4 - Indicates the number of threads to use. -c128M - Customize the size of the file to create for testing. -C15 - Set the cool-down time after the test. -W15 - Set the warm-up time before the test begins. -d60 - Indicates how long the command will stress the hard drive in seconds. Here's a breakdown of the options we used in the first command (see step No. Once you complete the steps, the DiskSpd tool will test the hard drive performance based on the parameters you specified in the command.

If you’re testing an M2 unit, you can check out what we got on our current Air and Pro review units.Before proceeding with the performance test, it's recommended to close all running applications and ensure that the storage health is in good condition. Your best way to see if your Mac is getting a good score is to look around at the reviews, which are generally about devices that are ready to use right out of the box. You can change the size of the file that the application uses to test reading and writing in the Emphasize menu above.
Read speeds measure how fast your device can access files on its system Write speeds measure how fast you can save items to the device. The test runs continuously and you can see your reading and writing speed.
Once the program is downloaded, open it and click Start speed test. Search for Blackmagic and click the download button next to the hard drive speed test result. #Understanding blackmagic disk speed test results how to#
How to run the Blackmagic Disk Speed Test If you are using a Mac computer and are curious how well the SSD is performing, there is a very simple benchmark you can run called the Blackmagic Disk Speed Test. Different models of the same product can even have wildly different storage speeds, as we’ve seen with the latest MacBook Air models. Sometimes it’s not obvious, especially on a new computer, how well your memory is performing.
