As you point out, Galbraith’s results supported my own. There are also a large number of other factors that influence buffer depth and write speed – such as noise reduction and ADL. I also don’t see how you confirm that the card is “twice as fast” in your tests. But thanks for the comments, the more people share their experiences, the better.

Chuck, further to your test of Extreme card. I tested that card in my D700 and found it noticeably faster than Extreme III. See my review at http://fullframestories.com/sandisk-extreme/

Either you card was bad or there is a significant performance difference between D300 and D700. They might also redesign the card since you tested it.

I think you should give a second chance to the card. According to my results it is twice as fast as Extreme III and much lower cost than Extreme Pro.

Amen. Sometimes I feel like I’m on a crusade against sites that test cards in readers, or worse, in some sort of industrial gadget like manufacturers do. Card-to-PC speeds are important, but they’re only part of the story.

Card readers on computers are a completely different story. I use a Lexar 600x that gets 70-90 read/write in my reader but 45 in-camera. PCs perform completely different than cameras.

That’s always possible. However, two things lead me to believe otherwise: one, Rob Galbraith reported similarly poor results for the D300s and 1Ds Mk III (though not for the 5D Mk II). Secondly, “21-22 shots in RAW” could mean many things, since RAW buffer size depends on a wide variety of factors. I have not conducted card reader tests of this new generation of cards yet, although Galbraith’s results are quite good. That, combined with his better observed performance in the 5D Mk II, lead me to believe that there’s an obvious issue with this card and some UDMA-enabled cameras – something that shouldn’t be there when cards above and below in the same product line have no problem.

Hi,

you may have had a defective or outdated sample of the Extreme 60. Just got one. In my cardreader, my new 16GB card gives me 58MB/s write and 79 read, and in my D300s I get 21 – 22 Shots in RAW – does not sound too bad to me (The old Extreme IV gave you 17, according to the manual).

Thank you for the feedback, I was just about to head out to get a new Extreme card and I needed a clear comparison between Extreme and Extreme Pro. You have made my choice very clear!
