A: A memory card is just
a compact storage device designed to hold
photos, videos, audio and other multi-media
files. They are designed primarily to be inserted
directly into devices such as digital cameras
to store digital photos and other files. Files
on them can easily be downloaded to your PC
and then cleared or deleted once no longer
needed. They can also be plugged directly
into other devices such as digital photo frames
and some models of computer printers.
A: Flash as in "flash
memory card" just refers to the physical
type of memory used in the construction of
the memory card. Most common memory card types
(e.g. CF, SD, xD) are built using flash memory.
A: Just insert the memory
card into the relevant memory card slot on
your digital photo frame. Typically the frame
will accept a wide variety of the most common
memory cards and many additionally accept
USB memory sticks. Your digital frame will
allow you to play a slideshow of all the photos
that are stored on the memory card, and in
addition some digital photo frame models will
support playing movies and audio files.
A: SD memory cards
are currently the most popular format memory
cards in use, as well as being the best value
for money. SD cards come in different capacities
such as 1GB, 2GB and 4GB. They also come with
different speed ratings which refers to the
speed that data can be transferred to the
memory card. For example a high speed card
would be labelled as say 130X and may have
a transfer rate of 20 Mbps. Anything over
60X is generally considered to be a high speed
card.
Q: What
are CF (Compact Flash) memory cards?
A: CF memory cards are the
second most popular format of memory cards
in use and are used by a significant number
of Digital SLR cameras. There are 2 types
of CF cards: Type I (3.3 mm thick) and CF
Type II (5 mm thick). CF cards come in a variety
of storage capacities, from 1GB all the way
up to 16GB. CF cards above 2GB use the FAT32
file system.
Q:
What are MS (MemoryStick) memory cards?
A: In 1999 Sony debuted their
own flash memory product called the Sony MemoryStick.
They are used primarily in Sony Cyber-shot
digital cameras as well as Sony Digital Video
cameras. They tend to be one of the most expensive
formats of memory cards. The original MemoryStick
card was limited to 128MB capacity. Sony has
since introduced the MemoryStickPro (MSPro)
which has larger capacities up to 2GB and
faster transfer speeds.
Sony also supplies a MemoryStickDUO card which
is half the size of the original MemoryStick
and was designed to fit inside their super-compact
digital cameras.
The latest generation is now known as the
MemoryStickProDUO which was released in 2007
and has storage capacities of up to 8GB and
very fast transfer speeds. They are also priced
very highly when compared to the more widely
available SD and CF formats.
Q:
What are MMC (MultiMediaCard) memory cards?
A: MMC cards are nearly identical
to SD cards on the outside but internally
are different. In fact the SD card design
was based on the MMC card for compatibilty
purposes. The MMC card format has steadily
declined in popularity since SD cards were
introduced. Not all cameras that take SD cards
can also take MMC cards.
Q: What
are xD (xD-Picture Card) memory cards?
A: xD Memory Cards are an
ultra-compact form of memory card designed
jointly by Olympus and Fujifilm to be used
by their digital camera products. They are
reasonably popular and there is ongoing development
with the format. They tend to be a higher
priced memory card format.
Q: What
are SM (Smart Media) memory cards?
A: SM cards are one of the
earliest forms of memory card and come with
a maximum storage capacity of 128MB. The SM
format is not undergoing any new development
and is generally considered to be a 'dead'
format. No new digital cameras have been introduced
which support this card format since 2003.
Q: What
are USB flash drives or USB memory sticks?
A: Strictly speaking, USB
flash drives are not 'memory cards' as such
but they do perform a similar function. They
are not used by digital cameras but rather
are a form of portable storage, which, given
their USB interface, are extremely easy to
use with a PC. Also, most digital photo frame
models allow you to directly plug in your
USB flash drive to play a slideshow of all
the photos and files stored on it.
