    Works well, easy to use. Only complaint is that it sticks out of a USB port, so it's possible to bump against the PC/Port and snap it off. Happened to me once already and lost data because of it. Not under vendor warranty for this kind of mishap, so I was out of luck. Trying it again (and being more careful) as performance /price point was good.

    I was looking for storage for a lot of HD photos at a low price. The SanDisk - Ultra 128GB USB 3.0 Flash Drive worked well for me. I had no problems with the flash drive.

    Picked up the thumb drive on sale for $35, great value for the money. I am able to backup all of my files for transport using the thumb drive in a relatively quick manner since it is USB 3.0.

    I've bought a Samsung Flash drive before that failed within one week of light use causing me to loose all my data. Upon further research I found this one and the ratings looked great so I decided to give this a try and was not disappointed. So far the read and write rates are great and the drive is correctly recognized by my laptop and my pc.
