Description

AJA System Test Lite is a great way to test a storage system with a real world speed test. Designed with digital video production and post production needs in mind, it emulates the writing and reading of video files to and from a hard disk and displays the results in a simple, easy to read format, by either data rate or frame rate, including graphs to show performance over time.

Users can specify resolutions, color spaces, bit depths, compression types and file container types, to emulate their specific digital video production/post workflow, and do preliminary evaluation to see if their storage system will support it, before practical workflow testing begins.

For professional use

I'm amused by the reviewer who gave this app a low rating because it doesn't include a manual. Ma'am, it's a benchmark testing app intended for use by professionals who already know what all of the options mean without needing any explanation. While it can be helpful for others to use [ie, non professionals], you can't blame the publisher for being uninformed yoruself. If you looked at their website you'd find all sorts of products that you don't understand...but that wouldn't be their fault, now would it?

For the rest, who know what they are looking at, this app is great and needs no explanation. It works. Period.

No manual or info

This app (Lite version) shows read and write speeds to the volume you specify. It says it is designed for supporting video product work. I was told to use it as part of trying to identify some disk failure issues with an SSD connected to MacOS Sierra. It is a pretty mystifying piece of software actually, with no information about how to use it or what its results mean. The Lite version doesn't dump its results anywhere so you use screen capture I guess for recording results. You can use it to get some sense of the relative performance of different drives on different ports and interfaces (e.g. USB vs FW).. If it encounters a problem, you are SOL. On a write error, it just stops in its tracks, leaves its datafile on the drive, and has some difficulty using that drive again. I'm not sure what finally cleared that condition. It was interesting to see how bad the performance of a FW 800 drive was through a Thunderbolt adapter when compared to the same drive using USB3.

Easy to Use Tool

This performance tool was easy to use and provide useful data.

I was debuging a disk performance issue and used this tool to verify the issue and solution. Even with the focus on video performance, I used it just to measuring raw disk performance. I plan to use this tool again in the future to debug system issues or verify disk performance.

Thank you AJA Video Systems for making it available.
