    This is a great value, lots of memory for the money; it is easy to use, drivers downloaded automatically, no problems whatsoever using this storage device. 128GBs of memory, wow! I have been able to access stored files quickly, without a hiccup. I have also stored well in excess of 100 very large files, and still have 120 GBs remaining.

    Great flash drive with 128 gb, which is a great amount of storage for my purposes. It was also on sale, so that makes it even better. I have used other sandisk flash drives which have proven to be reliable.

    My PC does not support the next level of MS security. The team at BB was helpful. Today, I went back for some more help, and Zion helped me out. At this time, a new PC purchase is a stretch. However, Zion and the rest assured me that the San Disk has all my files. Also, I was advised to check Webroot, which I have, and will try to program for frequent scans. I plan to be back in Best Buy the next time I have a product need.

    It amazes me how much storage they can fit on such a small device. Easy to use, and even easy to reformate to fit the larger files on it that I needed to.

    Good USB drive, poor key chain design

    I purchased this USB drive to get large capacity, a low price, and a keychain design. The drive works fine, but the key chain portion forces the drive out of the casing when it is in my pocket. The ring pushes on the mechanism that pushes the drive out. I'm worried that it will cause eventual damage to the data. Once I can find a better design, I'll probably be transferring it over.

    It works well; pretty fast because it's USB 3.0. I use it for booting ISO images as part of a system administrator toolkit, and it behaves perfectly. Well worth the cost.

    A SanDisk flash drive, nice 128 GB capacity, USB 3.0 and the slide mechanism works well. Great for taking projects with me from my regular PC to use when visiting relatives and using my laptop. Also great for backing up important files. Has the quality you would expect from a plastic housed flash drive build wise. Has a spot to hook it to your key chain as well. I am pleased with it and glad I got it.

    Got this to consolidate the 5 other USB stick I have. This one is by far the fastest and has the most space. Runs a bit hot after you transfer a lot of data but otherwise great device.

    I was in the market for a larger capacity flash drive than the 64 GB ones I have now. My main purpose was to use it for archiving and HD backup. Item was described as USB 3.0 with a speed of up to 100. Keep in mind this is a burst speed, not a continuous speed. The price was right, so I ordered online, used a $20 gift card and my cash outlay was minimal. Delivery was a day before promised, too. Very good shopping experience in all aspects.

    I recently upgraded to this disc drive, and I'm very impressed. The read and write speeds are excellent—file transfers are noticeably faster, and my computer boots up quickly. It offers plenty of space for all my files, games, and media. Installation was straightforward. It's also very quiet and runs efficiently without overheating, which I appreciate. I highly recommend this drive for anyone looking to improve their system’s performance without breaking the bank.

    Love these things for moving gigabytes of photos from one computer to another or into drawers for long-term storage. USB 3.0 sure lets you finish the task fast. SanDisk Flash drives are trouble-free and the under $15 price tag helps too.

    I needed a USB key with more space and after some research settled on this one. It is compact, fast, and has plenty of space for an OS X boot image. If anything I would have wanted the USB cover to be a little harder to open but it stays in place as is. I would recommend this drive.
