    The drive is very fast with reading and writing. The construction seems sturdy enough, though it doesn't compare to an all metal case. Overall a great product for the price

    When you need to transfer large amounts of data, I highly recommend getting a USB drive with a lot of memory so you can do a one stop deal and not run into problems of not being able to transfer because file was too big. At 128GB, this should take care of most of your needs.

    I bought this flash drive for storing my security camera footage. It was instantly recognized, formatted, and performs as expected. We shall see about durability as time passes. A major reason for buying Sandisk for me is that I have had a very positive experience in the past with their warranty and customer service.

    These are the fastest USB 3 flash drives available at Best Buy that is in-stock at the store. At least 33% faster than the PNY's. Great USB flash drives used for imaging. I've purchased over 50 of them along with 20 PNY. Both are good, but the San Disk ultra is much faster.
