    This product is fabulous. Well made and plenty of room to load hundreds of documents on for those who are on the go with the laptop or iPad. Can’t recommend it highly enough.

    This ScanDisc USB is working great. I needed a way to transfer music CD's from my old laptop to this USB.

    Need a quick alternative to an external hard drive back up. did not realize that thumb drives have such huge capacities, such as 500GB meaning half a TB. Awesome idea, and SanDisk I heard they are awesome ! And awesome price as well !

    does exactly what its made to do, but I held back one star only because it takes longer than it should to show up on my computer. No other flash drive I've ever used has that problem.

    Fast loads. Plenty of space for files of all types. Word docs, music, videos, etc. I don't believe any other company besides SanDisk has a USB drive of this size currently.

    We had purchased the 256GB version for the kid's laptops & iPhone back up. We purchased this 512GB version for us to back up our home computer and both our cell phones. Worked flawlessly with room to spare. This holds a lot of data. It's fast and has had no glitches so far.

    Great usb. My son decided to get this one which has plenty of space. I gave him $20 dollars extra so he could get the bigger space. He was happy to have not this one instead of the smaller one. For the price difference this made more sense.

    Small but BIG. I saved all my data in my old computer to this little Flash Drive. However it is only allowed any file that is less than 5GB in size to be copied.

    This is just what I needed. I create PowerPoint slide show on my PC, download it to this thumb drive, then load it on the PC at my church so I can add the PowerPoint to the streaming of the worship service. Works great.

    I needed a large capacity USB flash drive for backing up a significant number of important files on my laptop rather than relying upon my cloud storage to do so. The USBA drive is quick and offers 512 GB of space, which is great.

    I transferred thousands of pictures onto this flash drive. It took up a small fraction of the 512gb on this drive. I did not realize how great a capacity 512 is. I can add pictures for the rest of my life and never run out of space.
