2. Speed Matters to Me
I always pay attention to transfer speed because it saves me a lot of time when moving photos, videos, or large files.

One thing I value most is plug-and-play functionality. I want a card reader that works right away without complicated setup. In my experience, this makes a big difference when I need quick access to files on different computers.
