Why Brand Matters to Me
I have found that trusted brands are worth paying a little more for. Cheaper cards may look attractive, but I do not want to risk losing my files or dealing with fake capacity. A reliable brand gives me more peace of mind, especially when I store important photos, work files, or videos.
