Once done, click the Start button to begin the read and write speed test. Note: Blackmagic Disk Speed Test puts hard drive under extreme stress during data write and read operations, therefore it’s recommended to save your work before conducting the tests.īefore you start the hard drive read & write benchmark test, click Settings present in between write and read meters to specify target drive and load you want to put on your hard drive. Unlike other hard disk benchmark tools, it consistently performs write and read operations, so you can check both performance and reliability of your hard drive in real time.
