| | Does card speed have any effect on shooting speed? As far as i understand it all goes into the camera buffer.
Im thinking of getting Extrem III instead of IV for bigger size. III is still pretty fast but i can go upto 16GB and forget about any more cards.
bigger cards are totally necessary for shooting long (multiple days or weeks) time lapse. I have filled a 4g card in one shoot and that was in less than 24 hours. Imagine doing something like a flower blooming or a house being constructed. You would need the space for sure.
Look at any tests that have been done in the real world.
Well since I actually use the gear in the real world while you spend your time running around the forums professing about it to clock up your post score I kinda don't have to.
You don't have to believe me
You are right about that though! -mercifully.
Some of the newest high end cameras can utilize the faster cards to empty the buffer faster. Also, several smaller cards as safer in my opinion than 1 or 2 big cards. This has been discussed at length before. You might want to search the threads to see more opinions on this.
I did have a couple of cards fail on me but it was a batch problem that was fixed. Still though if I'm shooting something important like a wedding I'll use 3 cards in rotation; card 1 take a few shots, rotate to card 2 for a few more shots, then card 3 and back to 1 etc. And I'll do this all day with the idea that if anything happens to any one card then no large block of the days work will be completely lost.
I'm using 3 x 4GB cards and I have a couple of 1 GBs and a 2GB from before.
With the newer cameras saving increasingly larger files all the time I can see the need to upgrade to 8GB or 16Gb cards coming soon enough.
Just a thought - while I think that the above is a good idea, I also think that by doing this you may be hastening the demise of the card as I am guessing the time when it is most likely to fail is when getting constantly inserted and removed?
If I was to shoot that many pictures in one session, I would be tempted by one of the portable hard disks and 2 cards - shoot one til its almost full, back it up while shooting with the other.

It was a San Disk Ultra II SD card. Fortunately I didn’t lose any images. .. If you’re moving gigabytes, the extra speed makes a big difference.

What is the exact relationship between Microdrives and Compact ::
8 posts - 6 authors - Last post: Sep 16, 2004Is there any difference between a Microdrive and a Compact Flash II the Microdrive into order to make it act as a Compact Flash II card?

Anyway the bottom line is to find a solution that works for you....
Alright, i looked through a bunch of benchmarks and the conclusion is that any reasonably fast card will be as fast as anything while shooting on D300 level camera.
Download speeds using card reader are very different.
Failures occur very rarely and if they do almost all the photos can be restored - random sources so not sure about that.
I would stick with several 2g fast cards if i were you.
I find it easier to organise that way as well....labeling the cards and stuff.
But the choice is yours!

My biggest concerns on this is the card pulling the pins from the camera as has happened with a cheapo card reader one time.
The purpose of not shooting until a card is almost full is that too much time will have past, lets say the entire church cermony of a wedding. Now if that one card fails then my goose is cooked, but if I rotate them every five mins when appropriate I'll at least have some shots from the church.

Fake SanDisk Compact Flash card::
May 22, 2006 This email confirmed that the SanDisk Compact Flash card was not genuine, of the fake and genuine cards, to identify differences between them. This fake card isn't covered at all by any warranty. If you found this page useful, you are welcome to make a donation to help cover my losses.

The Big Dog high end cameras now include 2 slots that will remove the need for this swapping around.
CF Cards don't fail too often, and if they do many companies (especially Sandisk) have software to recover the data. I think the scare of failing cards comes from the days when microdrives were all the rage...these things failed all the time because they were basically a super tiny HDD, they had moving parts.
16GB cards are slow period...
get 2 or 4gb cards instead.
the thought of having 16 gigs on one card is completely and underly terrifying to me.
LOL@Sideburns
I just looked at the Sandisk 16GB Extreme III and the Sandisk 8GB Extreme III and the 4GB and 2GB that you recommended and guess what... they are all spec'd at 20MB/second sequential read and write. So when you wrote "16GB cards are slow period..." What exactly did you mean? Period.
They're "rated" at that speed. They are not the same speed, though.
Look at any tests that have been done in the real world. smaller cards of the same line perform better.
You don't have to believe me, but go look for yourself. Any legitimate real-world benchmarks show that the 1, 2, 4 gb cards perform better.
My understanding is that only extremely slow cards will slow you down while shooting... but that extremely fast cards unload much faster once back at home. If you've ever waited 15 minutes for 80-90 shots to come off your CF card, you know how valuable that time could be :-)

Thanks for sharing thoughts guys! How often do CF cards fail and cannot be recovered?
Seems to be few and far between...never happened to me...[knock on wood]

What about thoose data dumps, the wireless connection from your camera to a harddrive back in the car.
This is kind of on-topic I think, anyways, at CES (Consumer Electronics Show) last week, apparently some 48gb CF cards were unveiled at 40mb/sec buffer speed. That's pretty fast. But who needs that much space? Seriously.
I'm thinking of picking up a SanDisk Extreme IV 8gb card, but that's really the biggest card I'd ever get.
If you want to shoot your camera like a machine gun...then a faster card would be an advantage. If not, then I wouldn't pay a lot more for the 'fastest' card.
As mentioned, off load speed will probably be faster, and that may or may not be an issue for you.
Also, I have noticed that with slower cards, it takes longer to bring up images when reviewing them on the LCD...again, this may or may not be an issue for you.
Extreme III cards are pretty fast in their own right.
Big Mike is pretty much right in his comment, however, losing 16gb of info even once.......
I use 1 and 2gb cards. With the image sizes going bigger I might try a 4gb some day, but I agree with the others. All the photos on one card and depending on one expensive card, instead of multiple, less expensive cards, I like the idea of more cards.
I can set the card to download to the computer and go back to shooting, while it is saving. I have a stand alone CD writer that reads from cards, for backup. Same thing, and a CD only holds 702mb, so there's a limit. Nice part is I can just back up the whole card if I don't fill them past 3/4s.
Some people may think there's nothing more interesting than watching a card transfer for 15-30 minutes. (my laptop is older with USB 1 ports, so that's my fault) I have better things to do. :lol:
Hi There. I am no expert, but I believe that even though the data is run through the camera buffer, you still need to empty the buffer, which is where the speed of the card comes in. If you shoot single frame shots then the speed isn't as important as if you were trying to take multiple shots as fast as the camera can.
As far as the card size, I would be concerned about having all my eggs in one basket. If that card fails and it is full, that is a lot of images to loose.
Just my two cents.
Cheers
I did have a couple of cards fail on me but it was a batch problem that was fixed. Still though if I'm shooting something important like a wedding I'll use 3 cards in rotation; card 1 take a few shots, rotate to card 2 for a few more shots, then card 3 and back to 1 etc. And I'll do this all day with the idea that if anything happens to any one card then no large block of the days work will be completely lost.

CF cards will fail with 100% certainty at some point. The technology has a limited re-write count. For the record I have taken over 50000 photos on my old card and it hasn't failed yet. I just upgraded to an eXtreme III since my old EBay fake was too slow when shooting in RAW the buffer would fill up when photographing sports.
If you are going to be using 16Gb cards (not a good idea anyway) speed can't be that important in the first place.
What camera and what size files are you working with?
I've got 10 2Gb. cards and they handle a full days shooting for 2 cameras, no matter what, and I shot RAW.
That 16Gb. card really spooks me.
 Where was the last debate on wednesday with Mccain and Obama?
