The 16GB card is twice as large as the 8GB card, which we recommend for low-to-medium casual use. It's a whole new level of application, and a great storage device for anyone whose mobile or other device sees plenty of use on a day-to-day or even weekly basis. 

The Transcend 16GB card is good for casual users who take a lot of photos or video, as well as those of a more artistic bent. It's also great for storing a large number of songs, television episodes, or other fun data on your smartphone.
