AJA System Test For Mac

AJA System Test is designed to measure the input and output performance of your volumes, and it works by writing a certain amount of data while measuring how long it takes to read and transfer the info to your storage device, to your RAM or to a KONA Video capture card.

The AJA System Test utility offers you the possibility to tune your tests by changing the amount of data that will be processed during a test (goes from 128MB to 16 GB) and the video frame size (the amount of data that will be processed in each transaction).

Also worth noting is the fact that AJA System Test automatically detects all connected volumes and you can select the one you want to perform your tests on from the Volume drop down menu.

Moreover, if you want to test network volumes, you must check the appropriate box in the Preferences window.

AJA System Test provides six types of performance tests: Disk Read/Write, Disk Read Existing File, Sweep Video Frame Sizes, Sweep Binary Frame Sizes, Sweep File Sizes and KONA DMA (requires a Kona card and to have the driver software installed).

While using AJA System Test to test a drive, you should disable the file system cache to make sure that it does not interfere with the test readings.

Thus, by clicking the Graph button you will be able to visualize the test results in the drawer panel (you can also choose to view them in text form).

On the whole, AJA System Test is a simple to use macOS utility which will allow you to run performance tests on the storage drives connected to your Mac and determine if they work properly.
