xD Picture Cards are an ultra-compact type of Flash
memory that has been developed jointly by Fuji and Olympus and was
introduced in 2002. The name 'xD Picture Card' was derived from
"eXtreme Digital" and was chosen to reflect the excellence
with which the format would be able to record, store and transport
audio-visual information. The standard xD picture card writes at
3.0mb/s and reads at 5.0mb/s.
