    I keep several of these in rotation for everyday backups of documents. They work well and when Best Buy has them on sale, I buy a few for spares.

    When I saw the opportunity to a SanDisk 3.0 at more than 60% off I jumped right on it. This USB Flash Drive is everything it is advertised as and more. I am very happy with this purchase.

    I have purchased 12 of these Scan Disks 128 GB USB 3.0 flash drives, each of them at points where they were on sale. Each has worked flawlessly. Extremely easy to use and time-savers.

    I purchased this flash drive to be used for portable media storage. Write speeds to the drive were decent, but slower than the specs. Though I never get the maximum speeds with any flash drive. Media plays off the flash drive with no hiccups. I've always found Sandisk flash drives to be very reliable. I recommend only purchasing them on sale.
