Customers are saying

Customers find value in the product's ample storage, fast speed, and overall strong performance, often highlighting its ease of use and good price. The USB 3.0 capabilities are also appreciated, along with its comfortable size. However, a small number of customers have noted minor concerns regarding heat during data transfer and the design of the retracting case.

    It does exactly what it's supposed to do. I assume it works just as good as any other USB drive.

    This SanDisk 64GB Flash Drive is certainly fast. I do not use the included encryption software app as it makes me feel anything but secure. I just want something that works. Of course I back it up with another flash drive just to be safe.

    Bought 2 64gb and just used one so far. Works just fine transferring files, but gets a little hot when connected to a PC usb port. When moving a lot of files it didn't take long to finish the task.
