I can't find this anywhere? I tried apple but it want me to upgrade to El Capitan to access it, this is a free app so is there a link here somewhere I can't find?

For some reason, the App Store one demands el capitan, and the other versions are all bundled with other stuff.

I recommend using AJA's version anyway, at https://www.aja.com/en/products/aja-system-test

Standalone, mac and windows versions, easy to find, plus it will graph your results. This is very helpful when the drive you are testing works in bursts. An average speed that is good may still fail with video if the slowest speeds are too low for recording. It's a very similar program, but with the ability to graph the speed over time. I've had several SD cards pass on BMDs app, but fail on that one, with very slow spots in the graph.

just donload the Desctop Video upgrade bundle. There should be a disk speed invluded, the drivers for the hardware that you don't have you can delete..
