    I recently purchased USB drive sun disk. Downloaded all my pictures and videos on it. Videos doesn't show on another computer though, but I am working on it. Probably, I just need to install soft to view them, which I didn't do so yet.

    Just needed to plug it in and it was ready to use. So far so good. Lots of memory capacity, so hope to keep all my files in one place. Very portable. Comes with file encryption software to assist with security and protection of sensitive files.

    Very simple - plug in this memory stick and it works. As a side note, it works in a Vizio smart tv's usb port even though I don't think it's supposed to support the memory sticks over 64 mb. I formatted it with ntfs first though.
