But if e-mail and Dropbox are perfect solutions for sharing only a few documents at a time, USB 3.0 Sticks are a faster and more secure method for sharing large files.
With USB 3.0 technology, faster USB storage units can even compete with external hard drives (hard disk drives) that perform better. With the advantage of being much more portable.
