The SanDisk Extreme® III
are extremely faster than conventional storage media.
That’s because only SanDisk Extreme III memory cards feature innovative
ESP Technology. ESP stands
for “Enhanced Super-Parallel Processing”. Simply put, it means
you are getting the fastest read/write speeds available – an
minimum 20 MB 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.
They are ideal for the special needs of professional
digital photography, since photos taken with high-value cameras
need a high speed storage medium.
What are SD Cards?
The SD Card is now the
most popular memory card format.
It is a further development of the MultiMediaCard and has additional
functions such as data encryption and a write protect switch.
The SD Card (32 x 24 x 2.1 mm) has the same
footprint as the MultiMediaCard
(1.4 mm height) but is 0.7 mm thicker and has 9 pins instead
of 7 and a theoretical data rate which is four times faster.
It uses the same flash technology as CompactFlash and PC Cards, but
the data is transferred serially rather than the parallel data transfer
used by the ATA protocol.
The memory media is the size of a postage stamp and the cards are used
both in industrial applications and in consumer devices – especially as
a memory expansion for compact digital cameras or PDAs respectively
The SD High Capacity Cards Extreme III
with 4 and 8 GB
capacity are not downwards compatible to the
existing SD Cards. The
new SDHC memory media fits into standard SD Card
slots but applications as card
reader or digital cameras explicitly
need to be compatible with the cards.
