AJA System Test Application
AJA System Test is a utility for measuring system performance with AJA Io
devices. The application includes:
• System Disk Test
• AJA Device Test
• Disk + Device Test
• System Report
The application tests Read and Write, Capture and Playback speeds tests in both
Megabytes per second and Frames per second. The disk speed tests differ from
standard disk I/O performance applications in that they specifically test the
system under conditions typically encountered with video capture, playback, and
editing.
We suggest the best test is to fill your storage disk to 80% and then test capture at
the highest data rate you will use.
Connecting To Your Computer
1. Connect a Thunderbolt cable between the computer and the Io XT/4K.
2. Power the unit (AC supply or battery) and if it is Io XT, turn it on using the
power button on the front. Io 4K does not have a power button.
3. Cable the system audio and video sources, VTR, audio monitor, and video
monitor.
4. When you run the AJA Control Panel, you’ll notice that the Io XT/4K is auto-
discovered as long as it is properly cabled and powered up.
