Thanks for posting. I'm traveling and it will be very handy to review while I am on this trip.

Key question is how fast can the 5DM3 write to the card. I have not test these 2 cards, but with the older extreme and extreme pro cards (both 32GB) I did not a difference. On the 1Dx, perhaps there will be a differencePerhaps because if you need a whole bunch of cards, then whether you spend 50 bucks or 150 bucks does make a difference . And there's no guarantee that you will be able to use your cards in future as different standards come out and manufacturers switch to them....
If you indeed like to rattle off the frames, then the fastest you can afford indeed makes sense....
This is where I'm thinking lies. I can get a 32gb 160mb/s card for around $200 AUD and a 32gb 120mb/s for $120 AUD. I could get it off eBay but I'm worried about getting a fake....
I rarely shoot sport but it something I want to get into. I shoot more events and weddings.
I'd love to hear from someone who has both the 160mb/s and 120mb/s versions...
I just switched from the SD extreme pro 16gb (90 mb/s - the write speed was 45mp/s) to the new Lexar 1000x 16gb (2 pack for $99 at bhphoto)
I noticed a difference in transfer speed as the Lexar reads at 150 mp/s versus 90mb/s...so it's noticeably quicker when moving files to the computer.
But with my 1Dx, I often shoot 8-12 frame bursts and I notice no difference in write speed between 45mp/s to my new lexar's 90 mb/s.
So I doubt the extra speed will be noticeable for you if I don't notice a change from 45 to 90 mp/s...(and considering the SD you're looking at is 60 mb/s)
if i get some time i'll do a test (on my 5d3) and see what the difference is between my old sandisk and new lexar when shooting continuous raw at 12 fps.
The change in write speed does not show up as a faster shooting rate on DSLRs. What it DOES show up as is a deeper frame buffer. The Canon 7D, for example, originally had a 15 shot frame buffer. When I moved up to 600x CF cards, my frame rate was still 8fps, however I started getting 23-24 frames in my buffer before it slowed down. After the firmware update, were Canon officially increased the frame buffer to 25 frames, I started getting 34 frames with my 600x cards.
The benefit of cards with faster write speed is longer continuous shooting times before you get reduced rate. You also clear out the buffer faster, so once you do fill up, if you wait for it to empty, it empties quicker.
I just checked Sandisk's website and looked at the specs of the two cards I'm comparing.
The Extreme Pro 160 mb/s has a write rate of 150 mb/s and read of 160 mb/s.
The Extreme (or Extreme plus - some stickered/marketed) 120 mb/s has a write rate of 60 mb/s and read of 120 mb/s.
Does this ultimately mean I can shoot more and faster on the Extreme Pro compared the the Extreme (plus)?
Or am I confusing myself?
E.g. I shot a tennis game the other day, in particular a person serving, on a 5d3 and it felt like I didn't get as many shots due to slow down...? Am I missing something or is that the speed of the card I'm using (which was the extreme pro 160 mb/s) or just the FPS one the 5d3?
that thread is on a fred miranda review using canon lenses on an a7r for landscapes.
The 'net is all abuzz over this product
My introduction to the fstoppers site was this review.......
After that bit of false frivolity, I now take everything I see at fstoppers just as seriously I take http://newcameranews.com/ . I find New Camera News funnier though.
Seriously, I'll take technical and product recommendations from Kai Wong at digitalrev.com before fstoppers.
When you format, did you do a slow format or a quick one?
When you do a full format, the computer writes over every block back to simple 1's and 0's. It takes forever. A quick format just marked everything as deleted and is consequently recoverable.
I might be wrong about that, but that is my understanding.
I just format with the camera. So for a CF card you don't have a choice. With SD I do a low level format.
I appreciate the irony that an embarrassingly trivial announcement of a new backpack color quickly digressed into a discussion of using tupperware lids for lens caps, and it actually became a far more useful thread. Now, if we can get Canon to put blue rings on the outside of the big whites we could have a yellow-and-blue makes green situation and know our lenscaps are on.
you just made my day....
I hope this one will go to production.
All in all, I'm thinking that a high megapixel body is becoming less and less appealing for manufacturers.
