SanDisk Extreme IV – Flash memory card – 16 GB – CompactFlash









This card has good capacity, which I have found necessary for my Sony Alpha-900, full-frame DSLR. Obviously, the bigger the file-size, the more room one needs on a card in order to cover a shoot.
This card is also very fast, which is important in taking rapid bursts of exposures; and also in downloading the results. I use the SanDisk FireWire card-reader for downloading, and it is very fast and reliable.

Previous to this 16GB Extreme IV card I was utilizing 2 X 2GB cards with much slower data transfer rates. The Extreme IV is much more convenient. Not having to switch out cards is a huge plus for me. Buy with confidence!

My review!!!
The product is good overall because it allows enough space for me to take pictures in RAW format if that is what I decide to do. Plus, it has the speed to handle the picture processing. That is all. Mark Ward

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.
