Fuji and Olympus have developed XD card with the largest capacity of 1GB in 2004. And the read-write speed is faster (reading rate is 5MB/S, and writing rate is 3MB/S). It satisfies large amount of data write-in and has a lower consumption. XD-picture card can not only be used at PC adaptor card and USB card reader, but also Compact Flash convert adaptor. It also can be used as a storage medium of Compact Flash in DC. Although it is a little expensive, with the decreasing price of Flash Memory chips and card, the price of XD card is going to decrease too.
Olympus began to earnestly move away from the xD format with the release of the E-P1 camera, which supports only SD memory cards. In 2010, all new Olympus cameras announced at the 2010 Consumer Electronics Show and Photo Marketing Association International Trade Show can use SD cards.
As of 2010 the xD format is obsolescent. New cards are still manufactured, but cameras supporting xD memory cards exclusively are no longer manufactured. Previously, xD competed primarily with Secure Digital card (SD), CompactFlash (CF), and Sony's Memory Stick.
XD card Contains no flash translation layer (designed to emulate the block device structure of a magnetic disk drive). Better-designed flash file systems can directly access the NAND flash hardware.
