Tips:
The actual available capacity for data storage is a little less than what is listed on the products. As this part of the listed capacity on a flash storage device is used for formatting and other functions, thus: 
2GB is about 1.8-1.9GB
4GB is about 3.6-3.8GB
8GB is about 7.2-7.7GB
16GB is about 14.4-15GB
