With the advancement of mobile technology, everything associated with it has undergone sea changes. Bulky mobile phones gave way to razor slim phones, voice call replaced by video calls and introduction of GPRS, EDGE and eventually 3G technologies have changed one's perception of functions of a mobile phones. No longer are they only a mobile telephone, but a internet surfing device, a digital camera, a media player and a strong office tools.

As the number of functions increased, so did the need for space to fit in more and more programs and files. Initially, a couple of Mb as internal memory would have been sufficient for any mobile user because of the absence of many functions like video player or any high end functions. Later, especially during the music mobile revolution, need for additional memory packets to store data and files was felt. Memory cards started to become increasingly popular among mid and high end mobile users across the demography. Among all memory cards available today, flash memory cards from SanDisk is probably the most popular brand all over the world.

After being established back in 1988 as SunDisk, the company has closely followed and in many ways, guided the mobile technological advances. Today, SanDisk has many market leading products, competing successfully with other giant brands like Sony, Apple Inc and Samsung. Extensive product portfolio includes external memory cards of almost all types and kinds. Memory Stick Pro, Memory Stick Pro Duo, SD, MiniSD, and MicroSD cards – SanDisk has quickly emerged as one of the the most advanced and trusted memory card brand. Innovation has been another reason that lead to the emergence of SanDisk. Time and again, the company has been successful to surprise everyone by their innovations.
