Blackmagic Disk Speed Test

Blackmagic Disk Speed Test 2.2

This program helps you test your disk performance.

Blackmagic Disk Speed Test is exactly what its name implies: a program created to help you evaluate your disk writing and reading rates. This application might prove to be of good use if you purchase a new Mac and wish to learn how it performs under heavy processing demands.

Even though some of the reviews left on the product's homepage are related to the fact that the app isn't intuitive enough, I think it's actually very simple to get the job done with Blackmagic Disk Speed Test. I completed a disk speed test without reading the built-in help guide or any info on the homepage of the app. So, I'd say even an average computer user can handle this program without any problem.

The utility tests the writing and reading speeds of any disk that's being connected to your computer. I evaluated the app with an external USB drive (size 8GB) and selected the 1GB size of the test units. The program immediately displayed a complete report with the writing and reading speeds for various formats, like PAL, NTSC, HD 1080, and many others.

In my opinion, it's definitely worth installing this application on your Mac, especially since it's free of charge. It immediately offers you the information you need, is very simple to handle, and uses minimum CPU resources while testing your disk.
