FEATURES- Extreme III SDHC Card with Reader- 4GB (4096 MB)
Serious professional photographers who demand one of the fastest,
most rugged, and most durable memory cards on the market should
choose the SanDisk Extreme III SD card. Built to work under the
most challenging conditions, with SanDisk Extreme III you'll get
more speed, better performance, and unmatched reliability.
That's because only SanDisk Extreme III memory cards feature
innovative ESP Technology for the fastest speeds and highest
performance. ESP stands for "Enhanced Super-Parallel Processing".
Simply put, it means you are getting the fastest read/write speeds
available -- an amazing minimum 20MB per second sequential read and
write speed -- speed you'll definitely appreciate whenever you find
yourself shooting and storing pictures in harsh environments,
extreme temperatures or at high altitudes.
Every SanDisk Extreme III SD card comes with RescuePRO so you can
recover images, documents, mail, video, music -- just about any
digital file, with ease. Built with leading-edge media recovery
algorithms, RescuePRO lets you preview recoverable data before you
try to retrieve it. With RescuePro's unique recovery algorithm for
MPEG audio and MPEG video recovery (MPEG-1/2/3) what you see, and
what you hear, is what you can recover.
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.
* 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.
