Customer Reviews

reliable and super fast
I'm using this card in a Nikon D3 for about half a year now. I take about 1000 photos each week so my cards get a lot of use. As a professional I can't afford to loose anything due to card problems, so reliability is a big concern.

This card is one of the fastest cards available at all. According to Rob Galbraith it is the fastest 16 gb card available at the moment (July-2009). I can confirm that using it in my D3. It is noticeable faster than any other card I have and my timings match the numbers he has on his home page.

I have had absolutely zero problem with this card, I have never lost a single photo because of errors or things like that. I really can't think of anything negative about it. Even the price is reasonable.

To make full use of the speed your camera should support UDMA and obviously the same is true for the card reader. But there no disadvantage if you put this card in an older camera or standard card reader. It will work just as fine and reliable.

I can highly recommend this card to anyone who takes lots of photos but also needs a 100% reliable card.

When you shop for this card make sure it has the UDMA and 45 MB/s label. There was an earlier version of this card (early 2008) which was slower. The newer faster ones can easily be identified by the 45 MB/s print.

SanDisk's Reputation is Well-Earned
This is my first 16GB card. Previously I have stuck with cards no larger than 8GB, mainly because they are easier on the wallet (though the argument can be made that the 16GB cards are cheaper per GB) and because I am uncomfortable with such a large number of photos being housed on one card. Even with the 5D Mark II RAW files, we're talking 500-600 photos on a card, and with a single failure all of those photos could be gone. I don't mind carrying around a few more cards if I can minimize the lost data if this ever happens to me.

But between a few Extreme III 8GB's, some Ultra II 8GB's, a couple of Lexar Pro 300x 8GB's, and a handful of Extreme III and Ultra II's between 256MB and 2GB, I have not had a single failure on any card yet, knock on wood. And I was about to embark on a photo-heavy trip with the 5D Mark II, so I ordered the 16GB before my flight, to add to my existing stash.

This is a seriously fast card. As has been mentioned, according to the testing done by Rob Galbraith this is the fastest 16GB CF card out there, tied with the Lexar Pro 16GB in RAW transfer speed, and 1MB/sec faster than the Lexar in JPEG transfer speed. It tests slightly faster than my pair of Lexar Pro 300x 8GB cards in RAW transfer, but in real-world terms there is no noticeable difference.

If you're upgrading from Extreme III's, you'll notice the difference: it's on the order of a 25% speed increase. Upgrading from the Ultra II's? That's somewhere around a 350% speed increase over the 8GB Ultra II!!

If you can afford it, get it. You won't be disappointed.
