I have always been a great fan of Sandisk cards as they have always proven themselves to have very high standards and they live up to their marketing, and when they dont, they pull the product off the shelves and simply own up to the fault. Something other card brands have trouble doing.
Having a Nikon D300s to shoot with has it's advantages. One of the biggest is the dual card slots; SD/SDHC and CompactFlash. This made it very easy to test two dissimilar cards in a similar fashion, and compare the results. With a transfer speed capped at around 30mb/sec (according the the card itself) I found that even taking into account the camera's onboard memory buffer, the best I could get in a continuous mode sequence was 12 images, before it bottlenecked and had to space the shots out significantly in order to write them to the card.
However, downloading the images OFF the card in large batches was significantly faster than other cards I have tried, when the transfer was above 5gb in a single session, even though I had to use a USB adaptor because my internal card reader wasn't compatible with SDHC.
Summary: A sturdy little card that will save your battery, because it uses less power to read/write, is small and easily tucked away in large numbers, and carries the assurance of quality that Sandisk has worked so hard to build up. if your camera can take SDHC, you should seriously look at this card, or a larger version of it. Professionals should not really be looking at anything smaller if their cameras are rated for better than 10.1 megapixels and they shoot in RAW mode. With space for over 1400 images at 12.3mp, it's a smart option for the prolific 'shutterbug', and well within the price range for a beginner who wants quality right from the start.
