Mobile devices are essential for our daily life, but for most of us, the internal memory storage on these devices is inadequate. Unfortunately, this problem is only getting worse, as activities like photo taking, video recording, and downloading, demand increasingly more memory. As a result, many users expand available memory on their mobile devices by inserting SD cards. According to Strategy Analytics, 75% of smart phones include a microSD slot, which points to the fact that SD cards are now an essential feature for many mobile devices. The SD industry trade group, SD Association (SDA), continuously improves SD card specifications and protocols in order to satisfy the ever increasing demand for memory.
