    Purchased this flash drive to back up some files on my computer. With 128gb theres a lot of room, so storing all of my photos without running out of room, was a relief. The san disk 3.0 is faster than the older version with the 2.0. Using this helped out with the transfer time with the bigger file sizes.

    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.

    Great little flash drive with lots of storage

    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 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.

    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!

    So far so good. Fast speed and enough space for my music and movie files. This does come with security software but I wouldn’t recommend if your planning on using with a TV or other devices that’s not a PC.

    I was upgrading my computer and needed an extra thumb drive to move backup and move documents to the new computer. This is exactly what I was looking for. It was a great price and it was the perfect size I needed. Highly recommend.

    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.
