I finally pulled the trigger on a 5DIII which should get here early next week. :D

So I went to the local camera store today and purchased two memory cards.....

1. SANDISK EXTREME CF 32GB (60 mb/s)
2. SANDISK EXTREME HDSC PRO 64GB (95 mb/s)

The salesman said the larger/faster cards should always be used for RAW/Video.

He recommended the CF should used for JPG as its a fast card in its own right.

Is this how I should align the camera settings?

Thanks.

If you value fast xfer speed do not bother with any SD card. Do a search and you will see why.....your CF card will take a big hit if SD slot is used.

I've read that as well. Not sure though on how it really affects the cf card. Is the write speed to the cf card affected while taking images with the sd card in the slot? If so totally not worth having the sd card in the slot if you don't need it.

The problem is Canon went cheap and put an outdated SD slot on the 5d3, the bandwidth is being "shared" on the same lane so when the SD slot is used the CF speed get drag down to the same rate. Using the SD slot also affect the buffer on burst shots as well. I'd much rather deal with swapping out the CF card when its full then take a big hit on xfer and burst rate with SD card in place.

If it affects it this much then whats the point in having two card options?

Its useful to those who don't need or care about fast write speed or buffer, and want to pack in maximum capacity. Casual shooting, on vacation and such probably don't care about speed.

This is my style of shooting....if it can handle 4-5 shots a second that'll do me

The speed hit is only when you are writing images to both the CF and SD card at the same time. Just the fact you have an SD card in the slot does not slow CF writing down.

I keep an EyeFI SD card in the slot for overflow and when I just want to write to the eyefi card to do wireless previews.

Well disappointed, my Viao laptop comes with a super fast SDHX slot.
So aprt from being half the price I was looking forward to 95 MBS on SD and blinging fast down loads to the laptop!

Will this slow write speed on the cameras SD slot, adversely effect 1080p / 24 video recording?

Or normal studio work. On a max speed using the slow motor drive?

Does not using the CF card slot improve the SD write speed?

No, the speed of the SD card slot is due to a limitation in the hardware. Irrespective of whether or not you use a CF card, the top write speed is about 20 MB/sec. if I remember right.

Basically, the fastest card slots support the UHS-1 standard. Unfortunately, Canon chose NOT to use this type of SD slot in the 5D3, so the write speeds are limited. They did use a UDMA-7 CF card slot, though. However, if you write to both cards simultaneously, the speed is limited by the slower SD slot.

Canon put UHS-1 SD card slots in the SL1, T5i, 70D, and EOS-M. But not the 5D3. Go figure.

Of all those cameras I would have thought the 5D3, would be the one with UHS-1; especially as I do not think it could be addressed with a firmware upgrade. But then not sure about that.
WHY would they do this?

I really wish people quit parroting this because it is misleading and complete nonsense. It ONLY affects the speed when writing to BOTH the CF and SD card at the same time. Saying you should never even insert a SD card is false. The article you linked to and the Jeff guy they linked seem to leave out this important detail.

Several reasons:
1) Dual card backup, record the same to both cards in case one card goes bonkers later
2) JPG on one card, Raw on another: good for those that process only JPGs, but then want the raw later to fix issues
3) EYE-FI SD card so you can send JPG to the eye-fi and have it transmit to your computer or tablet, but put raw on the CF
4) Extra capacity, when you fill one card, it flips to the other card

Agreed.
I like the dual card for reason 3 and 4.
