With the majority of camcorders and even some digital cameras being able to record high definition video these days, owning a fast memory card is more important than ever. One card that certainly fits into that category is the '8GB Sandisk Extreme III 30MB/s Edition High Performance Card Class 6 SDHC' - yes, it's an impressive and long-winded title - but how well does it perform?
As I own both the 2GB and 4GB 'standard' versions (rather than 'SDHC') of the same product, I am able to compare the speeds of all three storage devices, but before I do, it's important to explain what SDHC means.
What is SDHC?
- - - - - - - - - -
SDHC or 'Secure Digital High Capacity' is a type of memory card which was introduced to support higher capacities. Apparently, all SD cards that have capacities of 4GB or more are classed as SDHC. You can only use SDHC memory cards with SDHC compatible devices, and unfortunately SDHC is not backward compatible with standard SD devices.
With a 30mb/s (megabytes per second) read and write speed, The Sandisk Extreme III 8GB SDHC is exceptionally fast - although not that much noticeably quicker than my 4GB and 2GB Sandisk cards (which are also lightening fast). Nevertheless, this particular product is suitable for any professional photography and video capture.
Does this memory card have any weakenesses?
In terms of its performance, no - but the price-tag may put some people off - at £49.99 from Amazon, it is fairly costly. That said, only five or six years ago a 1GB card would have retailed at over £150.
If you're looking for a fast and reliable SD card, then I would whole heartedly recommend this model, which is perhaps the quickest you can get. It is built to withstand huge variants in temperature, with the manual claiming it will work in Arctic Circle and Sahara Desert conditions - impressive stuff!
