Re: Slow transfer speed with DVCProHD material

these are rough tests. Most companies that actually understand how to do drive speed tests do not value AJA system Test (I do however).
Unix tests like dd or netperf will show accurate results. Hi end drive tests like IOmeter are not available for the Mac Platform. So I use what I can get - AJA System Test (and rarely Blackmagic Speed Test). All you are going to measure is maximum performance.
