I need to buy some more SD cards since I have decided to shoot RAW. I ordered a 8gb Class 10 Transcend card as a back up and want to buy a really good card.

So my question is what is the best SD card? I am currently looking at the new SanDisk Extreme Pro sd cards which look very good. Has anyone used them? If this is card for me I will either get it in 16gb or 2x8gb.

Any help would be appreciated!

I personally use the SanDisk Extreme class 10 16Gb SD cards, and I absolutely love them. I've had a card from another company go bad on me, and since then I stay away from cheap cards. Also, class 10 enables me to take stills during my videos, and not have the video stop on me.

I think at the moment, SanDisk's UHS-1 cards are the cards I would buy...

I use SanDisk Extreme Pro 8GB cards as they currently match exactly my battery life for shooting RAW.

They're pretty fast as well

It's interesting that Lexar cards aren't so popular,even though they're pro memory cards as well. In some speed tests I saw,the Sandisks always came on top,which is just a bit dissapointing for the Lexars,since they cost about the same. (of course,the speeds are almost indistinguishable for most people)

Well, i am kingston user, i bought class 10 32GB sd, which is not really that fast (only little bit faster than class 6)

but enough for HD video, and burst speed.

and if i compare it with sandisk ultra2 with 9mb read / write speed, and 70€ price tag, 50€ kingston seems a better performer.

Using a SanDisk Extreme Pro 16gb.

Always have had good luck with SanDisk.

Well, i have a Pretec 32Gig 433x U1 Fulll HD video SD card, and it performs even better than my kingston one. It says it is class 16, but performs only 1-2MB faster write, still it is noticeable, and card is even cheaper than kingston. So i reccommend Pretec now.

Thanks guys I did end up going with the Sandisk Extreme Pro and I have been using it for quite a while now. All I can say is it performs floorlessly and it is very quick. I have 2x16gb of these and plan on getting a 32gb and 16gb compact flash version when I buy the 5D2.

I have a Canon 450D.

At present I’m using a Sandisk extreme card which has a 45MB/s read/write speed.

When I shoot on the highest quality jpeg setting I can fire off as many shots as I want provided I fire in bursts. When I switch to RAW + jpeg the camera locks after a couple of shots.

Would upgrading to a faster card resolve this issue? I was considering one of these cards.

Thanks in advance for any responses.

I looked up the Canon 450D and the buffer is rated for 6 frames in RAW. While the faster card might help to clear the buffer faster it will still depend on the maximum speed the camera can write to the card. With a buffer of 6 frames in RAW format I doubt you'll see a big improvement.

How big are your RAW files? I believe your camera is 12MP so if the RAW files are 12Mb is size with a speed of 3.5 frames per second it would have to write 42Mb/sec which is close to the limit of your card. So the speed advantage of the faster card might not be very visible.

That's just my opinion of course.

i just ran a test with my T4i (650D) and found no increase in performance between one of my SanDisk 45 MB/s cards and one of my 95 MB/s cards. Similar to your 450D, "continuous" shooting slowed (but didn't "lock") after just 2 RAW+L frames.

Mark

P.S. Interestingly, I do notice a difference when shooting hacked high-bitrate video on my GH2. So I'm guessing the bus speed of the GH2 is faster than the T4i.

Thanks guys.

A quick google turned up this thread so it might be a problem with the settings I'm using. I'll have a play with it over the weekend.

Something to note when getting SanDisk's UHS-1 cards, will your camera read them? From what I understand the Nikon D7000 was the first camera that could use these cards. I have two SanDisk class 10 16MB in my camera.



Cheers

The best SD card?

The one you have with you, of course...
