History Of Flash Multi Media Memory Cards For Digital Cameras And Other Electronics
Digital cameras have evolved from the early days of 35 millimeter film to high definition, and now to memory cards as a storage device for images. Digital cameras can now hold thousands of pictures with a single memory device, called flash memory cards. There are a variety of memory cards on the market, making

it nearly impossible for new or first time shoppers to properly comprehend which is compatible with their piece of electronics. You must be weary of fake or imitation memory cards often sold on the market. It is notorious to find lower than advertised memory card sizes on sites such as eBay. Always look for a reputable online vendors or brick and mortar store before purchasing flash memory cards.
The main types of flash memory cards are used for digital cameras include: CompactFlash (CF), SmartMedia (SM), MultiMediaCard (MMC), MemoryStick (MS), Secure Digital (SD), Secure Digital High Capacity (SDHC), xD Picture Card, and MicroSD. The cards are not interchangeable and must be used in the proper device in order to store the information. You must read the instructions to see what memory card is compatible with your specific digital camera.
In the beginning there were CompactFlash (CF) cards. SanDisk created this in 1994 and it has become a standard in storage devices, mainly digital cameras. In the past few years, smaller cards have been introduced to the marketplace, yet CF still remains a favorite among many consumers for its extraordinary capacity and consistency. They are available in capacities ranging from 512 MB to 100 GB. The most commonly sold size is 1 GB to 16 GB.
A year later Toshiba developed SmartMedia Cards to compete with CompactFlash, MiniCard, and PC Cards. Smart Media are no longer sold and are outdated. Do not buy this unless your device specifically uses these cards. They have been out of circulation now for many years, but older electronics still use them as a storage device.
MultiMediaCard (MMC) was developed in 1997 as a storage device that is easily transferable to computers. Currently 8 GB sizes are to hit the market, showing how far behind they are compared to MicroSD cards, whi
1000
ch can hold 100GB. MMC cards are small allowing them to fit into devices that cannot hold larger sized flash memory cards. In recent years MMC's have been replaced by Secure Digital Cards.
In 1998 Sony created MemoryStick (MS), a removable flash memory card. Along with this came the faster MemoryStick PRO, the smaller MemoryStick Duo, the even smaller MemoryStick Mico (M2), and ultimately the MemoryStick PRO-HG a faster version of the PRO.
Secure Digital (SD cards) and Secure Digital High Capacity (SDHC cards) were designed in 1999 to be superior to the older MultiMediaCard design. Unfortunately, both SD and SDHC cards are identical to one another, making it difficult to differentiate. The drawback to this is that SDHC cards are not compatible with SD cards, easily confusing consumers. Be cautious when purchasing these to make sure you are getting the appropriate memory card. Compared to MMC, SD cards are asymmetrical to prevent incorrect insertion, are thicker, and have much faster transfer speeds. MMC's can fit into SD card slots, but not vice versa. SD cards can fit in CompactFlash and PC slots, but most are connected through USB ports.
xD (Extreme Digital) Picture Cards are used mainly for digital cameras and were created in 2002 by Olympus and Fujifilm. The new ones may have compatibility issues with older cameras, so be sure you are buying the correct version of the xD Picture Card.
Created in 2005 by SanDisk, MicroSD cards (Secure Digital), commercially are the smallest and most cost efficient flash memory cards currently on the market. Newer MicroSDHC (Secure Digital High Capacity) are not compatible with as many devices as its older counterpart. Initially available in 32, 65, and 128 MB, now 2 GB cards are sold for as low as six dollars.
In general here are many options when it comes to choosing your flash memory card. Always make sure that your digital camera supports the memory card you prefer, or do not buy that camera. It is amazing how quickly the storage capacity increases, while prices decrease. I will not be surprised to see 100+ GB memory cars become standard and available for under $25. It is on the verge of happening within the next few years. Happy shooting!
