I have used this pendrive. It is too good. It is small, portable that can be used to store, access and transfer data. Due to its small size. We can read, write, copy, delete, and move data from computer to pendrive or pendrive to computer. It comes various storage capacities of 2Gb, 4Gb, 8Gb etc. It is popular because it is easy to use and small enough to carried in a pocket. This sandisk pendrive is very good.
