When shooting to CF cards I'm generally told that's a good idea only to only use a 8GB or 16GB a time. Therefore if the card somehow fails or gets damaged or lost that at the very least is just one portion of what you've shot. However with 8GB hold hundreds & hundreds of digital photos why would you even need a 32GB CF card?
CF is the standard memory card type for Canon DSLRs which are highly popular while SD cards are usually more for compact cameras. The 7D, 5D II, 550 D, 60D and all the other DSLRs in the Canon range all use it but why do you need so much capacity and is it reliable?
When shooting large fine Jpeg coupled with the RAW setting in some of the DSLRs suddenly you are recorded up to 30MB of information with every photo and if your sports or wild life photographer on a long days shoot this should about cover it. The other reason is video. Canon cameras record 1920 1080p HD footage and typically shooting 40 minutes of video will be about 16GB. If you want 90 minutes you will need 32GB. You also need the record speed of the card to be able to handle the mass amounts of information coming in.
This CF card has the minimum write speed of 20MB/s and a read speed of 25MB/s or 133x speed. So it should be able to handle all the information you need it for in terms of photos & video. It comes with a standard plastic card case which is good for when you carry it around in your pocket. It doesn't come with any data recovery software and has a limited lifetime warranty of 10 years. It tends to work well in most weather condition excluding the extreme. I've worked with it in snow and I'm aware it has a maximum operating temperature of 60 degrees C.
This card very much satisfies my needs and I would recommend it to any photographer.
