Yes you used the card-reader. But you will get different result depending on what reader you use, So without any info it doesn't say much. I have five readers and the results are very different depending on what reader I use. And depending on what interface the reader use. Like Firewire, USB 2 or USB 3. Just like the results are very different if using the cards in five different cameras.
Yeah, I'm sure the reader does matter a bit. I used USB 3.0, so I don't think it would be limited by my connection type at least and 3.0 reader (that said all 3.0 readers may not be alike). At the least, it puts the cards in relative order of potential for write speed in this case I think since USB 3.0 is fast enough to not bottleneck anything and the card reader doesn't seem to bottleneck writes up to the speed of these (for reads it might be a bottleneck though as the other guy got some pretty speedy reads compared to mine).
For stills shooting due to various buffer issues, it is true that an in cam test is what tells the real tale, although knowing if it has full UDMA 7 or not still lets you get something out of card reader tests to a point. For ML RAW video though, which is what many have been talking about lately, these types of benchmarks are more useful I think as they can have some bearing so long as the connection and card reader are fast.
