It’s been declared the top PC innovation of all time, and for good reason. You use USB every day to copy files, print information, and charge devices.
If your PC is less than five years old, chances are you’re using USB 2 (also known as USB High-Speed). It works well for moving a few of documents or a music file, but if you move large files or a lot of files, you’ve undoubtedly yearned for a faster option. USB 3.0 (also known as USB Super-Speed) came on the scene in January 2010. This new standard significantly reduces the time required to move information. Thunderbolt, developed by Intel and brought to market by Apple in early 2011, is just starting to appear in Windows PCs and offers improvements over existing USB technologies.
