If you are familiar with Terminal commands, you can run commands to test disk speed on your Mac. By entering the terminal commands, a 1GB file is read or written, and the test times this duration.

Here's how to test disk speed on Mac with Terminal:

  1. Open Terminal from Finder > Applications > Utilities.
  2. Type the command below and press Enter:#Disk Speed Test Write: 
    time dd if=/dev/zero bs=1024k of=tstfile count=1024
    #Disk Speed Test Read: 
    dd if=tstfile bs=1024k of=/dev/null count=1024
  3. Then wait for the output.

If you are not familiar with Terminal, there are some other programs you can choose to test disk speed on Mac such as iBoysoft DiskGeeker, it supports disk speed tests for both internal and external hard drives, and it is pretty easy to use. You can free download it to have a try!
