The card is good, and will ensure that the bottleneck for delays will be in the camera's circuitry, not in the write operation to the card post click.

However, read the description of this particular item carefully. What you get is a what they say here - a card in an anti-static envelope. The card that I got did not look new - the contacts had use marks on it. I am keeping it because I did not notice this detail in the description, because I got a great price, because I needed to use it right after getting it, and because it seems to work fine. But it isn't new - not that the description said anything about it being so.

I have personally tested several examples of this product against many other brands and models. In my D80 I find the JPEG write speed to be about 9.5 MB/second. It writes raw data at about 8.5 MB/second. Nothing else I have tried is close; not even the highly rated Lexar Professional Series 133X.

I have never experienced a failure of any kind with this product.

For anyone with a fast 10-megapixel camera that accepts high-capacity SDHC cards (check with your manufacturer!), this choice is a no-brainer! Nikon USA reassuringly has this specific card on their "approved" list for the D80 and other recent DSLR models.

Shooting in high-quality RAW format, capacity is now up to 326 images (or more), meaning less chance of running out of image storage -- usually at the worst possible moment -- when you're paying more attention to the scene before you rather than the image count-down indicator. And if you shoot in .jpg format, you now have a virtual warehouse for your images. The free USB reader is a bonus, allowing for quick, reliable image transfers to your hard drive, Mac or Win.

The downside? As of June, 2007, these cards are still relatively expensive and in scarce supply. But, based upon past SD card history, it should become a non-issue over the coming months. Still, if you want speed, reliability AND capacity for your new digital camera NOW, this card is worth the price.

I was having problems reading SDHC Cards on my SD readers, but no problem using my camera. So I scoured all the sites for a good deal on SDHC readers. I was dumbfounded about the inexpensive price that included the Extreme III cards. I have purchased two 2GB Extreme III cards that are great. I can take 3 shots/second with this card. Incredible stop action pics for tennis and football.

The card reader is smaller than my old one I loved, what a plus. It takes the SDHC without a hitch. It comes with a groovy holder that protects the reader and card. This one is definitely a photographer's friend.

I wholeheartedly recommend this combo and I would like to thank everyone that has written reviews on Amazon because I come here first.

The SanDisk cards are great and this is a good price. The seller tacks on about $4.25 per card for shipping and handling even though it probably cost them less than $1 to ship two cards to me. But, even with that "hidden" charge it was still cheaper than I can purchase these locally.

I ordered two cards. They were each packaged in the standard plastic shell case for an SD card and then inside a static bag, but without retail packaging. They appear to be new and unused. (I suspect that these discount sellers obtain these by breaking up bundled product sets, like a digital camera kit which includes the camera, a battery, a charger, and a memory card, and selling the individual pieces for a discount price, but I don't really know for sure).

Note: These cards are available from several different sellers on Amazon, this review is for the seller BlueProton.

This device does exactly what it claims and a bit more. Every other memory card I have benchmarked has been overrated, many shamelessly. Sandisk claims 20 MB/s and I measured 20.1 with HD tach, with a 20.2 burst rate! My digital pictures are 18 MB so I definitely need the speed and Sandisk Extreme III brings home the bacon. Well done!

I bought a new Canon PowerShot G9 recently. I had to buy a new memory card. My Canon PowerShot G6 took CompactFlash cards.

Comparison between CF and SDHC

Cost

I had to buy a 2 GB CF card at RadioShack for $80 while I was on Vacation in July. I bought this SDHC for $63, which includes a reader.

Download Speed

This card is much faster than the CF by far. It takes me half the time or more to download photos. Whereas my pictures on my Canon G6 ranged from 1 to 3 MB, the pictures from my Canon G9 range from 3 to 5 MB.

I never take the card out of the camera. I simply hook my camera up to the computer via a USB cord. It saves wear and tear on the card. I don't really use that much battery power from the camera.

Card itself seems fine. I bought this package instead of some of the cheaper standalone cards because I wanted the extras.

Sadly the MicroMate card reader is too wide to fit in some USB ports (including those on the front panel of my dell desktop and the side panel of my dell laptop).

If the RescuePro software crashes on startup, be sure to go into Windows Data Execution Prevention options and opt-out the rescuepro.exe to resolve the crash.
