    Not much to say about this product -- it does what is should: plug & play with no fuss, holds the stated capacity (minus the usual bit of overhead), easily slides in & out of its shell, useful activity light flashes when i/o is going on, decent performance, etc. Nothing to rave about, but a solid product & good value.

    I got this on sale so the price was "right". This product has functioned without problems. However, write times are slow for a USB 3.0 Flash Drive. San Disk claims speeds of "up to 100 MB/sec" and "up to ten times faster than standard USB 2.0 drives". I tested this drive and a USB 2.0 drive using the same USB 3.0 port and same 3.72 GB of family photo and video files. This drive copied the files at an average 5.6 MB/sec and never exceeded 5.9. The USB 2.0 drive wrote the same 3.72 GB of files at an average 6.1 MB/sec. The computer was idle during both trials.

    This 256GB thumb drive is a solid performer, and can store a reasonable amount of multi-media files and large data sets. The USB 3.0 standard provides fast data transfer rates. I highly recommend this product for a portable backup solution.

    It's a flash drive, so is pretty generic, but it's got tons of storage for the size, very convenient, and connects via USB 3.0, meaning it has fast transfer speeds. If it's not on sale, it's probably not worth getting at full retail price, but when it's on sale for $20 or $30, it gets much more attractive.

    I wanted something smaller than an external hard drive to store frequently referenced data files and this meets that need perfectly. We spent two weeks in Europe last year and it was easy to download all of our pictures from that trip to this flash drive. So far saving and opening files seems to be fairly quick.

    I used SanDisk - Ultra 128GB USB 3.0 Flash Drive - Black when I transferred all data from old tablet to my new one. Very fast compared to previous 2.0 usb and great space storage. I had a lot of videos and heavy files, really saving time. Very happy for this purchase, thank you Best Buy for the promotion!

    SanDisk is a reputable brand for USBs, so it will do the job. I bought a mini SanDisk USB which would occasionally overheat unfortunately, but had no issues with this. A good USB for an affordable price

    There's something about having 128gb of storage available to you in your pocket or on your keychain that puts your tech mind at ease. No more worries about "how can I get this onto your device?". Very fast, very reliable, very durable. Now I just gotta figure out what to do with my other thumb drives.

    I needed new flash drives for storing and transporting video files. I ran across these at a very good price. Free shipping was included so that was a plus. I got the flash drive in the time promised. Since this was USB 3.0, loading the files was very quick. Plenty of storage available too.
