    This thing is perfect as a back up. Music can easily be replaced, but pictures and videos CAN'T. Also it's small so clip it to something that cannot hide on desk, car, sofa....

    Holds enough data and transfer speeds are fine. It's well constructed and the blue light isn't as bright as previous Sandisk I've bought with the orange lights. I would recommend!!

    Love having a small thumb drive that I can store a ton of data, pics or whatever on! Don't always trust or have access to the cloud so makes saving my important pics and docs a cinch!

    As I write this review I notice that the regular price of this flash drive is $120. I feel I got a pretty good deal at only $20. It is really fast and works great with my XBOX ONE.

    Maybe not the fastest USB 3.0 flash drive, but way faster than 2.0 for storing pictures and videos. Just remember to re-format to NTFS if you're storing large files or Windows images.
