In 1999, Mitsubishi and Toshiba lay a joint effort to build a convenient way to store your digital cameras and computers. The result was the cheap SD memory card.
These cards SD (Secure Digital), but all took the place of the MultiMediaCard (MMC), which for the most part, and significantly faster transfer speed and storage capacity of high density. The transfer rate low cost of conventional SD memory card is six times faster than the typical CD-ROM, with a speed of 66x to pass (1. 01 specifications).
The increased speed of the SD memory card, however, has a speed of 133x (1. Specification 1), allowing data transfer complex audio / visual and proceed to save microseconds simple. The standard data rate provides an opportunity for these files to record everything at once and instantly.
The feature that really makes these inexpensive SD memory cards much better than the old storage MultiMedia Card. Not only is broader conservation, but SD memory cards are available in a multitude of different capacities: 900kb / s ands of 10 MB / s, 16 MB / s, 32 MB / s, 64 MB / s 128 MB / s, 256 MB / s, 512 MB / s, 1 GB, 2 GB / s, 4 Gb / s, 6 Gb / s, and up to 8 Gb / s, which is so large that it may contain a library of films and very more!
Low Cost SD memory cards usually need a card reader or adapter to act as a connector to a central processor of some type (computer, video camera, etc.) but are also designed to use USB ports. Many modern electronic devices are made with an SD memory function or a dedicated port for SD memory card.
That such a device is (relatively) inexpensive another advantage of the SD memory card. The prices are different, as the storage capacity, but lower costs of providing an incentive for those seeking a sophisticated high quality product.
Costs vary from $ 10. 95-128 MB / s for $ 12 – $ 15. 00 of 256 MB / s, less than $ 20 for 512 MB / s. 1GB Prices vary but generally fall below $ 60. The cheaper brands such as Corsair and Kingston, the average between $ 35 and $ 45, while the most popular brands (SunDisk and Lexar) range from $ 50 to $ 60. The 2 GB SD memory cards are about $ 100 or more.
Gung Ho For those of audio / visual enthusiasts who want to build large files files, or for those that have many small files simple Word doc, the cheaper SD memory card is the best device to use.
