Fastest card for 5DM3 - do you still buffer out?
« on: March 23, 2013, 05:33:53 PM »
I normally use Sandisk Extreme Pro CF cards in my 5D M3 and then several people told me that they don't fill the buffer using a 1000x CF card.  I tried the Lexar 1000x card and the buffer still fills up.   I seem to get a few more shots before the buffer fills with the Lexar 1000x.

Has anyone tried other cards that are fast enough so that they buffer never fills?

Thanks

Not using Raw.  You can shoot jpeg all day long with a fast card.

Lexar 1000x CF cards made a big difference for me too on my 5DIII
Buffer still maxes out but and I only shoot raw..  I have been able to get quite a bit more in a burst when shooting sports.. Definitely helped out..

I have a 60D, but that's what I found.  Highest quality jpegs won't even come close to filling up the buffer and slowing down performance, but if I go with low quality jpegs and high quality raw files... I get maybe 6 or 7 shots before it slows.  Kinda sucks.

I found that a lot depends on what you do with the SD card. I use the 1000X Lexar, too, but take my SD out completely for the fastest bursts. Writing to the SD slows everything down dramatically.

what are you shooting that needs such a burst rate?

Granted, I don't do a lot of action shooting...but, with one caveat, with the Sandisk Extreme 60 MB/s cards I'm using, for all practical purposes, even shooting RAW, the buffer is unlimited. I mean, sure, if I just held down the button for forever, it'd eventually slow to a couple frames per second, but it's just not going to fill up in any reasonable type of burst shooting. And I hate to think of the editing nightmare to deal with that many photos!

That caveat is, of course, that I'm just referring to the CF card. As soon as the camera writes to the SD card, it turns to molasses in January.

So, if performance is a concern, I'd recommend either leaving the SD card out entirely or leaving it in but only in "auto-switch card" mode, and then just to keep from getting a "card full" error message. As soon as you fill up the CF card (or come close to filling it up, pace permitting), swap in your next CF card, and just use the SD for emergency overflow.

Cheers,

b&

I have set the camera only to shoot RAW to the CF card. I do not write to the SD card. Even my 45MB/s 64GB card gives me decent speed. The only time it was slow was when I was shooting the Flamingos as they flew. Well in all fairness I held the shutter button down for a while :)

I do need to get a faster card. So may be some time soon.

99.44% of my images are raw.

I use the SD card as an over flow.  If I catch it in time, I will change the CF card when it nearly full.  However if I go over a bit (20-50 shots), then I replace the CF card and transfer the images from the SD card to the CF card.

Perhaps a bit of extra work, but that way (1) I am always using the high spend CF, and (2) I have a super sized over flow buffer.

I notice that if I write to the SD card, the camera is really slow.

I use the SD card as overflow, always writing (except when I miss it) to the CF card, never set to write to the SD card.

I'm waiting for a low level format to complete on my 64GB Lexar 1000X (It takes about a hour).
 
I'll check tomorrow to see how many raw shots I get on high speed shooting before the buffer fills and the slowdown begins.

While we are on the subject... I have a Sandisk and a Lexar UHS SD card... so class 10, but basically 45 to 60 mbps... and I was shopping for CF cards the other day and I think the fastest I saw was 1000x in my budget range. 

So my question is how much faster is the cf card than the sd card?  Is it the write speeds which makes the difference and not the reported read speeds?

On the 5DM3 or just in general?  On the 5DM3, the CF slot is the racehorse. The SD slot is not UHS-1 enabled, and seems to max out at about 25% of what the CF slot can do (with the fastest CF card = Lexar 1000X)...
