 Good, but usually not better than an Ultra June 5, 2007
202 out of 208 found this review helpful
With my equipment, this 'Extreme' card is faster than an 'Ultra' only in a few situations. Usually, the two cards perform identically, and you can buy three Ultra's for the price of two 'Extremes'.
The 'Extreme' captured 29 RAW images in 30 seconds, while an Ultra captured only 23 (the camera supposedly can capture 3 frames/second). Using the computer's USB 2.0 card reader, the Extreme uploaded just a tad slower than the Ultra (1.2 seconds/frame, vs. 1.15 seconds/frame). When capturing JPG's, the two cards were about equal (85 vs. 86 frames in 30 seconds) with the Ultra a tad faster... a negligible difference.
If the camera could capture 5 frames/second instead of 3, or the card reader were faster, the 'Extreme' card might have been faster than the 'Ultra'; but this is the equipment I have.
So, if you know your equipment can take advantage of the extra speed and you'd rather have the slight speed advantage than have three cards ($29/each) for the price of two ($43/each), consider the 'Extreme'. Otherwise, I'd recommend using the 'Ultra'.

I really like this card. It's made well for professionals in real-world conditions. The package comes with a free neoprene carrying pouch, a plastic hard case, literature, and a cd-rom for the recovery & back-up software programs.
As far as speed, I'm not sure how fast it is, but I'd say it's equal to another brand of 2GB SD card that's rated at 150x speed. Of course, your camera's processing speed also factors in.
In my 10 megapixel camera, the SanDisk 2GB Extreme III SD card gives me exactly 399 shots (that's interesting, because another brand of 2GB SD card that I own gives me 404 shots).
So far, I have not had any data loss problems, and that to me is very important.
Fast Memory but the need could be questionable . December 15, 2007

Most Digital SLR's including those below 1000.00 dollars have an integrated buffer system that allows for minimum 3 shots per second. Because of this, the photos are not directly being written to the card immediately and this type of card is not needed. If you are shooting in burst mode - (As many shots continuously), then this card makes sense. Think of it as pouring water into a pitcher that has a hole in the bottom. if you fill the water faster than the water leaving the pitcher, you will need this card. It allow's the buffer memory to transfer more quickly to the card.
If you have a digital SLR and taking a shot every minute or so, you don't need this card. Go for an inexpensive SD card with more memory. It would be fine.
I would also recommend the Extreme card to someone who has a point and shoot camera since there is next to no buffer memory that transfer's the photo data to the card and the camera is more dependent on the write speed of the card.
might be more than you need July 25, 2007

i'll cut to the chase. the sandisk extreme is comparable to the lexar professional series. both are recommended for professional sports shooters and maybe wedding photographers. for everyone else, it might be better to be ultra than extreme. i'll explain: unless your camera shoots at 5 fps or faster you don't need this -- the next-speediest sandisk card, the ultra II, is plenty fast for any dslr 3 fps or slower. the only place the extreme makes a real-world difference is in burst speed, which will vary depending on the size of your camera's buffer and, of course, your camera itself. oh, and the downloading speed from camera to computer via usb might be a bit quicker with this. other than that, it's a high-quality memory card from a reputable company. used to be more expensive but prices are falling fast, so for the price it's not a bad deal (although it wouldn't hurt to search other sites for deals).

If you are buying a several hundred dollar camera, then at least have the sense to take advantage of it by buying a FAST memory card. I didn't expect much from this card, or for there to be a noticable difference. Well, was I shocked from my recent vacation when I was shooting photos left and right, and the people in my group were waiting 2-3 seconds before the could take another photo. Not only does it allow your camera to shoot faster, but it lowers your blood pressure as well, because you didn't miss the shot. I can never go back to using a regular speed card. The card worked as advertised. I love it.
