xD Card,Description

xD Card is another type of removable flash memory card. The xD Card format is primarily used with digital cameras; however that also means that the reader shows up on printers and personal computers. I understand that currently only two camera manufacturers use the xD format. The media reader on my personal computer and printer have a slot which accepts an xD Card flash module.

The xD Card card dimensions are: 0.79 x 0.98 x .067 in.
The memory size may vary,but currently ships as either 512MB,256MB,or 128M Bytes of flash memory.
There are number of other card types in this family,refer to the Flash Memory Stick Formats.
Refer to the graphic below for a comparison of the different sizes of flash memory.
