I have acquired a new 64gig SDXC card for use in my D800.

Having formatted it in camera and taken a few trial shots I was impressed by the speed of it.

Now after taking a shot I can view it and the histogram almost immediately whereas before using the CF card I had to wait for the green light to extinguish.

The only drawback as far as I am concerned is that I have to use the USB cable direct from the camera to download into Bridge as my card reader will not see the SDXC card.

The speed of download to the PC is also very fast.

I am going to use the SDXC as my Primary memory in camera, do you consider this wise or have you any misgivings, would appreciate your thoughts.

Cheers

There's no "magic" about SD.

Leaving aside other differences between the formats, if you have a CF card with read/write speed equal to your new SDXC card, it will be just as effective.

Thank you Brian

I'm well aware that there is no magic involved merely electronic gates, but until I can afford to buy

a CF card equal to the SD in size and speed, my question still stands.

If you're really asking about the pros and cons of CF vs. SD technology, we had a quite lengthy discussion about that a few weeks ago, here.

I didn't see any question. Did I miss something?

Tom, the question was in the last sentence.

Ahhh, so it was. I didn't see a question mark.

You man need to update your card reader to one that supports the SDXC card.

Each model of a media card has different characteristics and needs to be read by interface that knows about that model of the card.

You have the SD, SDHC, SCXC, and then you have the Standard size, Mini size and Micro size.

You can find out more about the SD standards at the SD Standards Association

SDXC Standard
Before Using Your SDXC Memory Card

As noted in the last link, if you insert the SDXC card, or any media card, with data and you are asked to format the media card cancel the operation because either your system cannot handle the card or their is some other issue you need to resolve.

I do not have an SDXC card, but if I did I would not hesitate in using it as the primary memory card in my D800. Right now I use an SDHC card and leave the CF card slot empty.

I have a SanDisk Extreme Pro 64GB SDXC, very good card, works well with D800...

I have a San Disk Extreme Pro SDXC 128GB and it performs exceptionally well in the D800.

If I understand, a given size and speed card in SD type and CF type will preform at the same R/W speed in the D800, no measurable difference. Has anyone verified this? The SD cards have only 9 pins, whereas the CF cards have many more pins. Since these pins must be utilized for power, ground, address and data, it seems the CF cards should have an advantage speed wise. The SD cards are lower cost than the CF, so what is the advantage of the CF type cards, other than they are larger and thicker....which may or may not be an advantage.

There's no material advantage between SD and CF cards of the same rating, especially when comparing cards from the best makers (Sandisk, Lexar, Integral, etc.).

SD and CF form factors are also a function of different engineering approaches to reading, writing and transferring data. CF cards have so many pins partly because they use a parallel data bus, presenting and outputting 8 or 16 bytes at a time, which are all sent together. By contrast, SD cards have a serial interface, which requires much more complicated timing to use to extract the same or faster speeds for a given storage size and buss. (See Wikipedia). Just different designs. It might be somewhat counterintuitive when considering the physical form factors of the cards, but the number of pins/contacts has nothing to do with the comparative speed of the card formats.

I do not think speed is a consideration because you can buy either card in a faster speed rating than your camera or computer will utilize. I like SD cards because my notebook computer has a built-in SD card slot. Also, I like the SD card edge connector rather than the CF pin connector.

Rocky

Speed is a consideration for me, the read and download speeds are import.

If a camera could write to the cards as fast as the camera could shoot then the buffer would not be of a concern to anyone, but that is not the case - at least not as long as raw or tiff files are being used.
