Extreme Digital (xD) memory cards are a type of flash memory primarily used in digital cameras. Olympus and Fujifilm developed the flash memory card system in 2002. The xD memory card comes in four varieties: Standard, M, H and M+. In Spring 2010 Olympus abandoned the usage of xD cards in its digital cameras in favor of SD memory cards.
Speed & Size
The Type M card had capabilities to extend to 8GB of storage space, though only offered up to 2GB. The Type M has a write speed up to 2.5MiB/s, with a read speed of 4MiB/s. The Type H cards were developed as a faster card for photographers who needed fast read and write capabilities. The Type H offers write speeds up to 4MiB/s, with read speeds up 5MiB/s; however, storage space is limited to 1GB.
Features
Both types of xD card feature capabilities for Olympus' Panorama feature, as well as multiple art effect functions. Such functions include 3D, cartoon and watercolor effects.
Size and Weight
Both xD cards are 20x25x1.7mm in size, and weigh 2 g.
Operating Functionality
Both the Type H and Type M cards can operate at temperatures between 0 and 55 degrees C, and in humidity up to 95% with full functionality.
Bundled Extras
The Type H card comes with the xD picture card holder (to store your picture cards), as well as a pair of 3D glasses with which to view your 3D images. The Type M is bundled with the xD picture card holder, but does not offer the 3D glasses.
