 Great product May 13, 2008
SanDisk 4 GB Extreme IV CompactFlash Card ( SDCFX4-4096-901 )I bought this card for my Canon Rebel XTi. It works fast and perfect. I love it.
Great Card, Fast May 10, 2008
I've used SanDisk Extreme CF cards since I got a digital SLR. I've put over 20,000 images through the card and not a problem. The really fast write speed allows the camera's buffer to empty faster, letting you get the next sequence.
4GB seems to be a sweet spot for CF cards. It is not to small that you have to swap cards as much and it is not too big that you risk corruption.
When coupled with SanDisk Extreme USB 2.0 card reader, 500 RAW images can be dumped in about 2 minutes.
I liked my first one so much, I bought four more!
This could be the right card for you May 4, 2008

With fast shooting high mega pixel DSLR cameras, the CF card can be a major performance factor. Write speeds, capacity, and power consumption all have an impact. The Extreme versions also have a wider temperature range, is impact resistant, and includes recovery software. Why purchase an expensive digital camera only to use a card that cannot keep up?
The Extreme IV cards read/write with a 40 MB/sec sequential read/write speed. These fast write speeds are desirable with large image files especially when uploading to a computer. DSLR cameras often have a buffer which holds images while writing to the card during continuous shots. At some point the card cannot write fast enough, preventing the camera from shooting until the buffer clears enough room for another image. In these cases the camera cannot write as fast as the card, the quick speeds may only be noticeable while uploading images to your computer.
As CF cards continue to decrease in price, they increase capacity. 1GB cards are inexpensive these days, but don't have the capacity I need. Two 2GB CF cards cost about as much and sometimes more than the same model 4GB CF card. Meanwhile the price of two 4GB cards is currently less expensive than the same model 8GB CF card. It appears that the 4GB is the current sweet spot on a cost per GB basis.
When it comes to the price, the trade off partially comes from power consumption. Other model CF cards may use more power to do the same job as this card to maintain a lower price. The Sandisk Extreme IV card's low power consumption means a longer battery life.
Special features of this card include withstanding temperatures from -13 to 185 degrees Fahrenheit (as indicated on the package). Since I live in Texas, I doubt I'll ever have a problem with the card getting too cold. It is nice to know that I could possibly leave the card in a car under the hot Texas sun and it may still work. I've yet to test this scenario, and it's unlikely I ever purposely will.
The high impact rating of this CF card provides protection from accidental drops and falls. For example; if you were to drop this card 10-foot above the floor, this card is rated to sustain the impact without damage.
Additionally, if something should go wrong, this CF card comes with the RescuePRO Deluxe recovery software. Fortunately I have had no need for the software. For that purpose I cannot give much comment on its usefulness.
I have never had the need to recover my images as CF cards are extremely reliable. However, if you are concerned about reliability, the Extreme IV cards have a dedicated technical support line (1-866-270-5532). Plus it's backed with a lifetime limited warranty outside Europe. The warranty excludes any issues or damages to the card resulting from use in other than its normal and customary manner, misuse, accident or neglect; or improper alterations or repairs.
People generally want to know how many images a card will hold. This is a difficult question to answer and greatly depends on the card, and the camera using it. The number of images this card will hold on my Canon 40D also depends on the settings used. Let me provide a few settings and image counts for an idea of what this card holds.
Shooting Raw w/ISO 100 - 313 images
Shooting Raw w/ISO 800 - 284 images
Shooting Raw + jpg w/ISO 100 - 243 images
Shooting Raw + jpg w/ISO 800 - 214 images
Shooting S-Raw + jpg w/ISO 100 - 366 images
Shooting S-Raw + jpg w/ISO 800 - 321 images
Shooting Large jpeg w/ISO 100 - 1107 images
Shooting Large jpeg w/ISO 800 - 880 images
Shooting Medium jpeg w/ISO 100 - 1815 images
Shooting Medium jpeg w/ISO 800 - 1508 images
Somehow several cards I had came up missing. Needing to replace my missing cards I did some research to find the replacements. When a great warehouse deal on this CF card was listed on Amazon, I decided to make the purchase.
I use both a 2GB and two 4GB cards shooting primarily raw images. Normally I could easily fill the 2GB card quickly, for general use it is adequate though. When I shoot sports action shots I use the 4GB cards instead. There have been many days where I have taken 200-300 pictures without the opportunity to transfer my images. The 4GB card not only gives me more storage space, but also permits me to change the card in a slow moment before it completely fills up. It is truly aggravating to lose a shot because the card filled up. For these reasons I tend to prefer the 4GB cards with my 40D. When considering the card size, one should attempt to balance price, convenience, and capacity. Having one card for all your images may be convenient, but it increases risk of losing all your images if something should unexpectedly go wrong. Having lost several of my cards, obviously this is something I know first hand. Luckily I didn't lose any images as a result.
If the temperature ratings or the Rescue Pro recovery software is an important feature for you, the Extreme IV is the card to get. Otherwise, consider purchasing the Sandisk Extreme III CF Card with many of the same features and save some cash. The Ultra II cards are also available; however they are an older, slower technology. The current price difference between the Ultra II and the Extreme III cards is not that much.
Overall, I do not notice the benefits of this cards speed over the Ultra II when used with the 40D. With twice the capacity, I benefit from quick upload speeds when transferring my images. The other benefits between this and the Ultra II are not necessarily a big plus for me. There is no doubt in my mind the Extreme IV cards are better than the Ultra II though. I like having the recovery software too. Even though this card was more expensive, I am happy with my purchase.
PROS:
Reliable
Fast read/write
Impact resistant
Low power consumption
Backed by a lifetime limited warranty
Recovery software included
CONS:
None
great card combo wih my canon 40D April 25, 2008
I agree with with the positive comments posted earlier. This card is great, and definitely keeps pace with the High FPS in burst mode with the various formats of JPEG and RAW.
I liked the card so much I am getting another one :).
I also picked up the Sandisk Extreme USB 2.0 Reader. The packaging says for extreme III but works just fine with Extreme IV CF cards. I was able to transfer about 1.5 gigs of pictures in about 1.5 minutes to external storage. Very small and also fits nicely in the camera bag.

The perfect memory card for the new Nikon D300. Very fast. The photographer never has to be concerned about having the next photo ready to shoot!!!
