    there are better choices

    This drive is very small, not in capacity but physically. It is easy to lose if you don't clip it on something. My disappointment is with the heat it generates. I only copied a few files and it got very hot. So, not recommended for large transfers even though it has the capacity. There is a another model of this drive that has an aluminum body. I would strongly recommend buying that one instead.

    Good price drive

    The SanDisk pen drive is fast, reliable, and easy to carry. File transfers are smooth, the build feels sturdy, and it works seamlessly across devices. A great value for everyday storage needs.
