Sandisk Extreme III 4gb SD Card
SanDisk Extreme III expands its award-winning, professional line
of memory cards with a new 4GB SDHC (Secured Digital High Capacity)
card. The SanDisk Extreme III 4GB SDHC memory card offers speed,
performance and reliability to ensure you get your photos every time. A
4GB memory card can store more than 2,000 high-resolution pictures or
up to 8 hours of MPEG 4 video*. As an added bonus, the card is
packaged with a bonus SanDisk MicroMate™- a $20 value – so that users
have a one-stop shop solution for capturing, storing and transferring
their images.
Advanced Features:
- Fast 20MB/sec sequential Read/Write speeds
- Ideal for demanding photo shoots under severe weather conditions – heat, cold, wind, rain, snow, etc
- Durable, reliable and thoroughly tested for heat, cold, shock and vibration
- Class 6 speed performance rating ( based on SD 2.0 specifications)
- Dedicated technical support hotline 1-866-270-5532 ( U.S. only)
- SanDisk's lifetime limited warranty (EMEA: 10 year limited warranty)
What is SDHC?
 To
support the higher capacity needs, SD cards are now requiring a
different design. The new SD 2.0 specifications which supports 4GB and
up, is called Secure Digital High Capacity (SDHC). The SD Association
has created and defined 3 speed classes to help you identify speed and
performance capabilities/minimum requirements of SDHC cards and their
SDHC host products. Details on the SD 2.0 specification: http://www.sdcard.org or SanDisk.com/SDHC
Cards address data (read and write) at numerous speeds. Many
factors impede this performance. SDHC guarantees a minimum read and
write speed necessary to handle recording high quality video and audio.
The maximum card speed may vary, but you can always depend on SDHC
cards to meet your SDHC host product's high quality performance
requirements.
SDHC Compatibility Information
Because SDHC works differently (supports the new higher capacity cards) this new card format is not backwards compatible with legacy SD format host devices.

The SDA speed class rating was developed to identify minimum data
transfer and latency requirements for a host application and provide a
means for consumers to match those requirements with an appropriately
rated SD card. For example, in the emerging application of real-time
video capture (camcorders, camera phones etc), in order to ensure
smooth capture and playback of video, the camera buffer RAM must never
experience a data over-run or under-run. This requires that the card
communicate certain parameters to the camera and then meet some minimum
governing parameters. An SDA speed class rating of 6 means that the
card will be able to transfer (with specifically defined latencies and
data allocation units) data in a random fashion without interruption.
Consumers should look at the intended host device to select the correct
speed class rating in the card they buy. Since speed class 6 is
currently the highest rating defined by SDA, it doesn't necessarily
mean that a speed class 6 is the fastest card that a consumer can buy
for all applications.
By contrast, SanDisk's minimum performance rating of, for example,
20MB/sec on Extreme III cards states the performance level that those
cards will deliver for sequential write and read operations in
non-real-time applications such as file transfers between a card and a
computer or in digital cameras between the camera's buffer and the
card. In this case, the statement of performance allows customers to
make a relative comparison between cards of differing performance and
price points. SanDisk Extreme III cards are also speed class 6 rated.
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. Read more.
