STORAGE DEVICES

Types ofstorage devises

CF Card: was developed by SanDisk

Corp and these cards are about the size of a matchbook.

: offer very high storage capacities and fast processing

times:suitable for video recording

SD Card

: smaller than CF cards and are used in over half of current

camera models.

MM Card (MMC)

: cards are even smaller cards used in a few pocket cameras

Memory Stick

: a proprietary format from Sony Corporation, is shaped something like a stick of gum. These cards are used only in

Sony products

Hard Drives: such as Hitachi's Microdrive and

Sony's Compactvault are high speed, high capacity hard disk

drives. These drives are so small they can be plugged into a Type II

CompactFlash slot on a digital camera or flash card reader. (Type I

CompactFlash slots are thinner).

One-time Used Flash Cards: have been introduced with the idea that flash memory is so inexpensive you can leave your photos on a card

instead of copying then to a computer. This is not recommended

for serious photographers.

• When you have more than one card, a case protects your spares.
