SanDisk was the first to develop the micro SD memory cards. They are solid plastic coated devices, based on electronic flash memory to store data. SD memory cards can be used with a number of electronic devices like laptops, digital cameras, camcorders, mobile phones etc. SD memory cards have been designed to give power-free storage and fast recording facilities to the user. The device is very portable and can be carried everywhere due to its small size and sturdy design.

With the increase in requirements and functions the need for storage space also went up. Earlier a few Mb of space was enough but with changing times the requirements are much more. With the introduction of music mobile, the requirement for added memory cards went up, as users wanted to store more files and data. Memory cards gained a lot of popularity all over the world. It was the collaborative effort from Toshiba and Mitsubishi which developed an easy and convenient way to store files especially for computers and camcorder. This resulted in the launch of SD memory cards. High speed SD memory cards allow the transfer of intricate visual and audio files to be processed and saved in a few microseconds. This is the reason why SD memory cards have the ability record all data immediately and at the same time.
