Extreme Pro CompactFlash Card worth the money?

->> Anyone have any experience with SanDisks Extreme Pro CompactFlash Card on a canon 1Diii?
Is there any difference in writing to the card/emptying the buffer with this card and its cheaper brothers (ie non "pro")? |

->> I would check the CF/SD performance chart at Robgalbraith.com,
upper righthand(?) corner, to see what they say about card speeds. |

->> According to Galbraith's page, the 1D Mark III doesn't write to cards very quickly. It appears to top out around 10 MB/s with CF cards. For comparison the 5D Mark II and Nikon D3 can hit 30 MB/s so that Canon is just a slower camera overall.

The test hasn't been updated since 4/16/08 so it doesn't include the newest Extreme and Extreme Pro cards. However even the Extreme IVs before them could hit 45 MB/s (but only hit 10 in camera) so I doubt the new cards will show much improvement in the 1D Mark III.
Where you will see a difference is when downloading to the computer, assuming you have the right CF reader. The newest SanDisk Extreme (2010) and Extreme Pro cards both download at about the same rate (60 MB/s) using the SanDisk Extreme FireWire 800 and Lexar FireWire 800 readers that I use. However if you use a laptop and ExpressCard reader the speeds of the Pro version jump up to over 95 MB/s.

Personally for the readers I use the extra cost of the Pro wasn't worth it. The regular Extreme seemed like a better value and still download about 15 MB/s faster then my old Extreme IV cards. |

| ->> The only problem with Robgalbraith's site is for older models he doesn't update against the newer cards. |

->> Phillip, this is most likely because the newer cards won't be any faster in the older cameras then the older cards that are already tested. This is clear in my post above.
The Canon 1D Mark III can only hit 10 MB/s with a CF card rated at 45 MB/s (same card in the Canon 5D Mark II and Nikon D3 gets 30 MB/s). Chances of a CF card rated at 60 MB/s making any difference are slim. The testing has already shown that the limiting factor is the camera itself.
Therefore those using older bodies are going to see the biggest gains from faster CF cards in the time it takes to download to the computer on deadline. In camera will be about the same. |

->> The 1D Mk III is not UDMA-capable so none of the UDMA cards are going to provide a significant speed advantage.
You could probably do just as well with the new "Ultra" series cards (I wouldn't even bother with the non-pro "Extreme"):

->> Here are my unscientific test results of several types of cards I have ranging from Hitachi Microdrive 4GB to Lexar 300x 32GB against the 3 readers I have, Lexar Professional FW400, Lexar Professional UDMA USB2.0, and Sandisk Extreme FW800.
