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 size SD card, so an SD card adapter may be needed to fix this issue. In most cases, the SD card is slid into or placed in an adapter that matches the electrical connections on the target computer. This allows the 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 typically no larger than a postage stamp and come in storage capacities ranging from 1MB to 32GB. This technology continues to evolve, bringing greater memory capacity in smaller packages.
SD cards can be used to store photos and videos taken with digital cameras.
SD cards are available in three different physical sizes. A typical SD card is about the size of a postage stamp and was created using the original design. Smaller versions include miniSD and microSD. The miniSD was released in 2003 and has the same large memory capacity but a significantly smaller package than standard SD cards. In 2005, the microSD appeared on the market, which was a quarter of the size of the miniSD.
With the design of microSD and miniSD, the need for the SD card adapter became apparent. 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 the miniSD and the microSD were aimed at the mobile phone industry. As phones got smaller, the memory cards that supported them also needed to get smaller.
Smaller cards usually ship with an SD card adapter so they can be used in other SD memory card devices. Using an SD card adapter allows you 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 make it easy to share videos, music, pictures, and other data files between devices.
You usually don’t need to buy an SD card adapter as they come with many smaller cards. However, adapters can be purchased at most places that sell SD memory cards. This is convenient in case an adapter is lost or misplaced.
