Why USB 3.0 Speed Matters to Me
One of the biggest reasons I choose a Card Reader 3 USB is speed. I often transfer large photo and video files, so I need faster read and write performance. USB 3.0 helps me save time compared to older USB 2.0 readers, especially when I am moving high-resolution media or backing up important files.
