Just a few decades ago, data transfer was a secondary characteristic of technology. Users were more concerned with whether a device could connect to a computer at all and whether files could be copied without errors. Today, the situation is completely different.

It affects how fast a device charges, what video quality it can play, and how comfortable it is to work with large volumes of information.
