The SanDisk Extreme Pro SDHC UHS-1 is the fastest SDHC currently on the market. That being said, I must point out that this card uses the UHS-1 standard which most cameras in existence currently do not support. I have the Nikon D7000 and as far as I can tell, it is the only camera that supports this card. Currently you can pick these cards up for about 75 dollars for the 16gb and 150-170 for the 32 gb. However, I suspect that as more cameras are released that support this card, you will see the price go up.
This card writes and reads at a minimum of 45 mb/second. This is 15 mb/s than the former fastest SDHC card on the market, the SanDisk Extreme Class 10.
Even if you do not currently have a camera that supports UHS-1 this card will still work and is backwards compatible with SDHC and SHXC devices. However, the card will revert back to standard Class 10 speeds approximately.
I could go on and on about the quality of SanDisk but I won't. Simply put, they make some of the best memory for cameras out there.
This is a great card, but it is not for everyone. I prefer it because I only shoot RAW (NEF for Nikon) and the files are typically between 25mb 30mb. The Nikon D7000 16.2MP DX-Format CMOS Digital SLR with 3.0-Inch LCD (Body Only) has a buffer of 10 RAW photos. When I get to the end of the buffer, this card starts with the magic. Where my Transcend Class 10 card would only allow me to shoot 2 shots per three seconds once I reached the buffer, the Extreme Pro allows me to shoot 2 shots per second when I run over the buffer. It also replenishes the buffer in about 4 seconds versus the 15-20 seconds the standard Class 10 cards would take.
So, this card may or may not be for you. If you shoot event photography, sports photography, or weddings, then I would suggest you buy a couple or more of these. If you are a casual shooter who never fires off a large burst of photos, I would save your money and buy a less expensive card like the Transcend 16 GB Class 10 SDHC Flash Memory Card TS16GSDHC10E that is one third the cost.
In the video I compare three cards, the Dane-Elec 8 GB Class 4 SDHC Flash Memory Card DA-SD-8192-R, the Transcend 16 GB Class 10 SDHC Flash Memory Card TS16GSDHC10E, and the SanDisk Flash 16 GB SDHC Flash Memory Card SDSDXP1-016G (Black). I start by shooting straight RAW photos until the camera's buffer is exhausted and then see how quickly the card can write to clear the buffer. I then shoot the cards again in Fine JPG mode. I do this to show that the three cards will all suffice if you are just shooting JPGs. I wanted to show this so that it would help others in deciding if this was worth spending three times as much as other Class 10 cards. Since the 8gb and 32 gb Extreme Pro are built to the same standard and architecture, the write/read performance should be the same and the capacity should be the only difference. As this is a SanDisk branded SDHC card, this is a rather safe assumption.
Overall, I would buy this card again.
-Cheers!
