jvandegr's Full Review: SanDisk Extreme III 133x (1 GB) CF Card (SDCFX1024...
Introduction
I recently purchased a Nikon D100 camera for use as a backup body in my photojournalism work. Because I work outdoors in all conditions, I decided to not mess around with my memory card. Truth be told, CompactFlash cards are all fairly durable; I've never had any model of any brand of CompactFlash card physically break or wear out. Some brands may be more reliable than others, but that's a different characteristic. The media itself is pretty stable, at least for short periods of time (less than five years). Still, when it's 0 degrees F outside, I don't want to be worrying about my CompactFlash card - my fingers are more important.
Features
From SanDisk's website, this is what the manufacturer claims:
- Designed to meet the critical speed and performance needs of serious professional photographerslets you quickly capture, view, upload and transfer large image files
- Ideal for demanding photo shoots under severe weather conditionsheat, cold, wind, rain, snow, etc.
- Built to perform in the most extreme environments and temperaturesfrom -13º F to 185º F (-25º C to 85º C)
- Min 20MB/second** sequential read and write speed
- Durable, reliable and thoroughly testedtemperature tested (heat and cold); shock and vibration tested (industrial-grade RTV included for CompactFlash)
- Data recovery softwareensures your photos will always be there (even if you delete them accidentally)
- Dedicated, priority technical support hotline for direct customers of SanDisk Extreme products
- Included travel case keeps your memory cards organized

**Based on SanDisk internal testing
***Except Europe
Note: 1 megabyte (MB) = 1 million bytes; 1 gigabyte (GB) = 1 billion bytes. Some of the listed capacity is used for formatting and other functions, and thus is not available for data storage.
What else is in the box? A brief SanDisk user guide written in so many languages you need to dig for awhile to find English, a mini CD installation of RescuePRO, and a travel case.
Performance
Reliability and Durability
I've had no compatibility issues with this memory card. In both a Nikon D100 and a Canon A95, everything has worked perfectly from the beginning. Likewise, this memory card is easily accessed from my Lacie memory card reader/writer without any problems.
Since I've never had data retrieval problems with this card, I've never had to use the data recovery software. Still, it's nice to know it's there if I do something stupid. I also like the idea of the priority support line, for the same reason, but I haven't yet had the opportunity to use it.
I've used the SanDisk Extreme III in western deserts with high heat and extremely dry air. I've also used in at high elevations (above 8000 feet) with temperatures down to freezing. I've had no problems with it whatsoever in either environment. I've noticed no measurable decreases in read or write speed in either environment. So far, the Extreme III has lived up to its billing.
Speed
And now for what everyone seems to care about: how fast is it? In this case, that question is mostly irrelevant for digital camera use simply because its write times are faster than any digital camera can really take advantage of, as of late 2005. Maybe in the future, the speed of this card can finally be taken advantage of and then will have some comparisons to make. In my Nikon D100, this card had noticeably faster write speeds than any other card I tried, including the best from Viking and Verbatim. I had a similar experience when writing image data to the SanDisk Extreme III via my Lacie memory card reader/writer.
Read speeds also seem to be faster than other CompactFlash cards I've used, but here the limiting factor is probably my computer and the memory card reader so this is a difficult claim to make. For reference, my Lacie reader/writer is connected via USB 2.0 to a Dell Dimension 8400 with 1GB of RAM and a 3.4 GHZ Intel Pentium IV processor. On this same system, my Viking and Verbatim cards may have had ever so slightly slower read times. Read speeds in the Nikon D100 were also very fast and again, obviously limited by the camera's processing operations and not the memory card; I've experienced similar read times with recent CompactFlash models from other memory card manufacturers.
SanDisk describes this card as having a "133X" speed, which is based on a standard of 150KB/second equal to 1X. This means that "133X" is not 133 times faster than some other manufacturer's card, unless their card was manufactured several years ago and they're still making it. In other words, don't be seduced by this "100000X" game.
Everything Else
The included travel case actually works pretty well. I thought it was a little gimicky at first but after using it in the field, it does provide that extra little bit of protection, which provides piece of mind. It is plastic lined, presumably to help keep out moisture, and has a 270 degree zippered side for easy access. A fairly large key ring allows for attachment to just about anything, which does come in handy from time to time.
Conclusions
I can easily recommend this card for use in any pro-sumer or SLR digital camera. As of late 2005, you're unlikely too find anything faster or more durable. Compact consumer cameras are unlikely to be subjected to the conditions this card was designed for, nor are they likely to be able to take advantage of its speed. In this case, go for something less expensive.
Are there alternatives to the SanDisk Extreme III? Consider Kingston's Elite Pro CompactFlash, as well as Lexar's Professional Series with Write Acceleration. For the latter, make sure your camera can utilize Write Acceleration. Both of these are priced a little lower for similar read and write speeds. However, they may not be engineered to perform as well under the extreme environmental conditions that the SanDisk is designed for.
