Many portable devices use Secure Digital (SD) cards. These cards are designed to be convenient for storing data and transferring it from one device to another. Not all devices use the same SD card size, so an SD card adapter may be needed to overcome this issue. In most cases, the SD card either slides in or is placed in an adapter that matches the electrical connections of the target computer. This allows use of the card within a device designed for memory cards of different sizes.
An SD card.
An SD card is a type of flash memory for storing data on digital devices. On August 25, 1999, SanDisk Corporation, Matsushita Electrical Industrial Co., Ltd. and Toshiba Corporation announced their collaboration to develop this type of removable memory. These memory cards are usually no larger than a postage stamp and come in storage capacities ranging from 1mb to 32gb. This technology continues to evolve, providing greater memory capacity in smaller packages.
SD cards can be used to store photos and videos taken on digital cameras.
SD cards are available in three different physical sizes. A regular SD card is approximately the size of a postage stamp and was created using the original design. Smaller versions include the miniSD and microSD. The miniSD was released in 2003 and has the same large memory capacity but significantly smaller packaging than standard SD cards. In 2005, the microSD, which was a quarter the size of the miniSD, appeared on the market.
With the microSD and miniSD design, the need for the SD card adapter became obvious. Many varieties of electronic devices use SD cards, including digital cameras, PDAs, cell phones, and video game consoles. SD card is one of the most popular formats for memory cards. Both miniSD and microSD were targeted at the mobile phone industry. As phones got smaller, the memory cards to support them also needed to get smaller.
Smaller cards are typically shipped with an SD card adapter so they can be used in other SD memory card devices. Using an SD card adapter makes it possible to transfer data between a smaller SD-compatible device, such as a cell phone, and a larger SD-compatible device, such as a computer. These adapters easily allow sharing of video, music, images and other data files between devices.
It is usually not necessary to buy an SD card adapter as they come with many smaller cards. However, adapters can be purchased from most places that sell SD memory cards. This is convenient in case an adapter is lost or misplaced.
