xD-Picture Card stands for Extreme Digital Picture Card. Olympus and Fujifilm released the xD-Picture card in July 2002. Kodak, SanDisk, and Lexar, also sell xD cards. xD cards are used in Olympus and Fujifilm digital cameras and Olympus digital voice recorders. Fujifilm also made an MP3 player that used the cards. As of 2006, xD cards are available in these capacities: 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB, 1 GB, and 2 GB. An xD card is 20
mm × 25 mm × 1.78 mm and weighs 2.8 grams. Fuji cards will not work with the Olympus autostitch panarama camera function.
There are three types of xD-Picture cards: Type S (original or standard); Type M (Multi Level Cell - MLC); and Type H (High Speed)
Type S also known as "Original xD" or "Standard xD" are available in capacities up to 512MB. Type S can be identified by the absence of a letter on the front of the card.
Type M is made with Multi Level Cell technology and has a theoretical maximum size of 8GB. Currently the maximum size available is 2GB. Type M suffers from a slower speed. Type-M
xD picture cards display an "M" on the front of the card.
Type H operates at a write speed of 4MB/s and a read speed of 5MB/s. Currently the maximum size available is 2GB. Type H xD cards support special "picture effects" when used
in some Olympus cameras, though these software features are not intrinsically hardware-dependent. Type H cards are also required in newer models to capture video at high rate
(640x480x30)." Type-H xD picture cards display an "H" on the front of the card.
