Hello,
we had the same discussion a short while ago on a German forum. I do attach the non-scientific results. It's not translated but I bet you can read it anyway.
Tests were rough and easy:
- Target a normal, brightly lit area with some realistic features (not white wall or with lens cap on).
- Set camera to Hi speed series. Set it to manual for maintaining high shutter speed.
- Set to 16M/DNG/****
- Fire until the buffer is full (this is alway 20-25 pictures).
- Note the time between the last (fast) shot and the end of the card writing red light going off (should be around 30-45 seconds)
- Check total file size on card via PC. Divide.
- Rinse and repeat 3 times to average out the results.
As the whole thing was meant to be easy there are many ways to discuss sense and approach. For me that is enough, I don't need more information or precision. That's why we ended up with three categories slow ("langsam"), medium ("mittel"), fast ("schnell"). Who cares, If a card writes at 14.1 or 16.7?
I personally want a card in category "fast", with 16+ GB storage space and the lowest price. Nothing else or more complicated. And I don't care about computer use speed or future uses. By then there'll be much faster cards with more space for half the price anyway.
