SanDisk Extreme III SDHC 4GB
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*.
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)
- RescuePRO data recovery software - ensures your photos will always be there
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: https://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.
