Speed surprisingly beneficial to camera performance PRO: Very Fast, Allows more continuous shots without filling buffer CON: Expensive The SanDisk 2 GB Extreme IV CompactFlash Card is so fast, when I held down my shutter release (with Rebel XT set to Raw) for 3 fps continuous shooting, 30 seconds later it was still firing (it may have gone longer, but I just gave up and took my finger off the button). The Rebel XT is only rated for 5 or 6 Raw frames at 3 fps. Apparently, this 40 MB/s card clears the buffer faster than the pictures can fill it up. I also feel very confident that I can take multiple shots in succession even while the camera is set to both Raw and Large/Fine JPEG (at the same time) without worry that the camera will be busy writing to the card. On one outing, I took 101 JPEG pictures (approx. 3.3 MB each) and uploaded them to my PC via the Sandisk Firewire card reader in less than 30 sec (est.). Note that you probably will need the Firewire reader to get the full 40 MB/s upload speed (from your card to your PC). This card costs a bit more than the Extreme III, but it gives a very comforting level of performance overhead. CONCLUSION: Best memory card available for DSLRs. Worth the money. Get the Firewire card reader if your PC has one of the two provided Firewire plug types. The Firewire connection on the front of my PC was not compatible, but the back one was. WOW...now that's fast! Added this Extreme IV card to my collection of Extreme III cards used in my photography. Works without a glitch. I set my camera (Canon 20D) on continous shooting, full RAW, aimed it at a visually busy scene, and held the trigger down. It stopped to complete writing somewhere around 8 frames. I'm pleased with that. Very Fast This product was purchased along with a Canon 40D DSLR. This combination has proven to be extremely fast. I notice no delays when shooting with this card. This by itself is probably of little relevance though as the camera is likely the slower of the two pieces of hardware (Canon doesn't spec it's transfer rates). It does make a huge difference however when uploading to the computer for backup/editing purposes. This memory flies when used with the SanDisk Firewire card reader!!! Cons: Very expensive considering even the cost of the last generation of SanDisk.
