Please find an answer The xD-Picture Card is a type of flash memory memory card, used mainly in digital cameras. XD stands for extreme Digital. The cards were introduced into the market in July 2002 and developed by Olympus and Fujifilm.

Toshiba Corporation and Samsung Electronics manufacture the cards for Olympus and Fujifilm. Other brands, including Kodak, SanDisk, and Lexar, now 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. Secure Digital (SD) is a flash memory (non-volatile) memory card format used in portable devices, including digital cameras and handheld computers.SD cards are based on the older MultiMediaCard (MMC) format, but most are physically thicker than MMC cards. The additional thickness offers two advantages over MMC cards: 1.

The contacts are recessed beneath the surface of the card (like Memory Stick cards), protecting the contacts from contact with the fingers; and 2. The SD card is shaped so that it cannot be inserted upside down, even slightly, whereas an MMC card will go in most of the way but not make contact if inverted. They also boast higher data transfer rates, but this is always changing, particularly in light of recent improvements to the MMC standard.

Most offer a write-protect tab on the side. This is not a switch, and it is up to the device into which the card is plugged to sense the absence of the tab from the front of the notch and protect the card from writes. Digital rights management features are available but are little used.

SD cards generally measure 32 mm × 24 mm × 2.1 mm, but can be as thin as 1.4 mm, just like MMC cards (see below). There are different speed grades available which are measured with the same system as CD-ROMs, in multiples of 150 KB/s. Basic cards transfer data up to six times faster (900 KB/s) than the standard CD-ROM speed.

Gh-speed cards are made with higher data transfer rates like 66x (10 MB/s), and high-end cards have speeds of 150x or higher. Some digital cameras require high-speed cards to record video smoothly or capture multiple still photographs in rapid succession. As of December 2005, most devices comply to the SD card specification 1.01, with maximum speed of 66x.

Gher speeds of up to 133x are defined by specification 1.1.Devices with SD slots can use the thinner MMC cards, but the standard SD cards will not fit into the thinner MMC slots. SD cards can be used in CompactFlash or PC Card slots with an adapter. MiniSD and microSD cards can be used directly in SD slots with a physical interface adapter.

There are some SD cards with a USB connector for dual-purpose use, and there are card readers which allow SD cards to be accessed via many connectivity ports such as USB, FireWire, and the common parallel port. SD cards can also be accessed via a floppy disk drive with a FlashPath adapter.

XD-Picture Card - the newest digital camera memory format; smaller than all other memory formats xD-Picture CardReleased in Early 2002 by Olympus and Fuji, xD-Picture Card is the newest digital camera memory format. Physically smaller than all other memory formats, and available (as of 5/03) in sizes up to 256MB, the xD-Picture Card appears poised to replace the older SmartMedia format. Www.

XD stands for "extreme digital. " In 2005 xD-Picture Card Type M came out.en.wikipedia.Org/wiki/XD-Picture_CardAn article of published in cnet. AuSnippet from the article : http://www.pcworld.idg.com.au/index.php/id;565623457;pp;3;taxid;121Secure Digital (SD)The big up-and-comer in small storage is SD.

SD cards are significantly smaller than CF cards (SDs are about the size of a postage stamp size and weigh around 2 grams), and come in 8MB, 16MB, 32MB, 64MB and 128MB sizes.512MB cards are expected to enter the market by the end of this year.SD cards were designed with built-in cryptographic technology for protected content, to ensure secure distribution of copyright data. The card's namesake security readiness is now a moot point, however. Though SD was intended to protect the music industry by incorporating the Secure Digital Music Initiative's digital rights management and copy-protection scheme, the specification was publicly cracked shortly after its publication, and the SDMI consortium is no longer active.

Secure Digital cards cost more than other removable memory types: about $180 for 64MB, or $320 to $330 for 128MB. Hewlett-Packard, Panasonic and Kodak cameras use the SD format. XD-picture cardA brand new addition to the removable storage format race is xDigital (Extreme Digital).

Two of the companies behind the SmartMedia card format, Fuji Photo Film and Olympus, have announced plans to move away from that card, choosing to develop a new format of their own. The xD-Picture Card is only 20x25mm in size. In terms of capacity, it is too early to tell how the XD Picture Card measures up because commercial products are not expected to be available until the third quarter of this year.

Olympus said it plans to launch the format with 16MB, 32MB, 64MB and 128MB cards, and follow with a 256MB card in December. The only other capacity firmly on the roadmap is a 512MB card due next year, although the company says the card specification scales up to 8GB. In addition to the cards, the two companies plan to put on sale PC Card and Compact Flash adapters that will allow xD Picture Cards to be used in devices supporting those formats.

Toshiba will also manufacture the xD-Picture Card. Digital cameras supporting the new storage format will be available in Australia in the coming months. Sources: link inside .

Digital Camera Memory Cards All are memory cards. Olympus and Fuji started off with xD memory cards to create their own market for digital cameras. SD cards will NOT fit into digital cameras using xD cameras and xD will NOT fit into SD digital cameras.

For NEW models of "XD" type digital cameras, there are now Type H and Type M memory cards. For amateur users of digital camera, you will NOT feel any difference in the speed. Type H is faster to save but Type M can save more pictures in the same size XD card..
