Portable USB memory sticks
Memory sticks are basically pocket-sized hard drives and are ideal for transferring and storing relatively small amounts of data such as word processing documents and presentations.
Portable USB memory sticks can be attached to keyrings, but with capacities now approaching 64GB at the higher end of the market, these handy devices can still carry thousands of songs or multimedia-rich presentations.
Based around flash hard drives (which operate more slowly than disk-based hard drives but have no moving parts), these sticks are able to interface with any computer using built-in USB connectors. Some memory sticks are also equipped with encryption to help you avoid sensitive data falling into the wrong hands should you misplace your gadget.
