I'm currently looking for a few Sandisk CF cards for my newly bought Nikon D4s,.im looking at either 1x64gig card or 2x32 gig cards but will decide on that later. My issue is deciding between the Extreme card and the Extreme Pro card and there is a big price difference. The Extreme is 120mbs and the Extreme Pro is 160mbs but that isn't the shot speeds and there is a big difference in shot speeds( 85mbs vs 150mbs). Will the Slower Extreme 120mbs card slow the camera down or will I not notice anything? I don't shoot much video and don't plan to. Any info would be helpful and may save me some money buying something that I don't actually require.
 
Im thinking that after that link that with the massive D4s buffer for raw files then its very unlikey that i would continue shooting other than in small bursts which may give the camera time to write the files to the card. Suppose if i can find a 160MBs card at a good price tgen im better just going for that.thanks for the link and the reply.
 
Cant comment on the D4s pal but the Canon 1Dx which is a equal camera you can notice a large difference in speed for the buffer to recover with 160mbs cards, considering you spent x amount of thousands on the camera its only right to get the best cards you can to use inside it.
 
Cheers Joe, you are probably right. I think the buffer on the 1DX is around 35-38 where on the D4s its much much higher so my thinking was that i could continue taking images as the way i shoot im unlikely to fill that massive buffer up which would allow time for the camera to write the files to the card.

No worries mate, When shooting at 11fps pal the amount of files when the buffer is full will mount up a lot, in that situation if you have some action to be photographing you really want the camera to be processing though them as fast as possible so you will be able to get that shot you may miss out on. The way I look at it, top of the shop cameras should have top of the shop cards otherwise you are missing out on the D4s full potential.

The buffer on the D4S is something like 60 14-Bit uncompressed files.

Gramps i will need to check but i thought it was something like 75-80. Not sure if that was higher with ir without the firmware update that came out recently.

Not sure if that wasn't more related to the use of the newer XQD cards but there's a reference here: http://nikonrumors.com/2014/11/04/n...ony-g-series-xqd-version-2-memory-cards.aspx/

It says "when you use the new Sony G ... cards" so don't know if the figure of 66 refers to the buffer size with any cards ... that's maximum size mind 14-bit uncompressed ... smaller files obviously make a huge difference.
 
Like with most things, you might as well buy the best you can afford :) even if there's no massive benefit with the camera, it'll be quicker to move images off with a decent reader and USB3 and it's a little more futureproof :)
