    I chose the SanDisk - Ultra 128GB USB 3.0 Flash Drive because I needed a memory stick device that was not only highly recommended by personal and professional associates, but was also on sale and priced right for y budget and needs.

    I bought this to have anoher flash drive but also to try the USB 3.0 speed. This is used with a computer that has a USB 3.0 port. Speed of file transfer is great! This was bought on sale at a ridiculously low price. I was surprised to get a large capacity and a USB 3.0 for the money.

    Transferred data from one computer to a new computer. Worked great. USB-2 on the old computer was slow to copy files, but uploaded much faster on the new computer using USB-3. SanDisk is my go-to card and flash drive manufacturer.

    Had bought my son a new laptop so purchase this drive to put the recovery files on it and he could put just about anything else he wanted to. Best feature was price. Bought when it was on sale and with amount of storage it had I could not pass it up.

    Purchased on sale as retail pricing is a bit high. Overall, an excellent drive. I basically use it for backing up files on my work laptop to relieve some of the internal hard drive usage. Does its job well and quickly transfers most files.

    SanDisk is the best brand of memory devises, as far as I know. So I needed to transfer precious family videos and photos, and knew this was the flash drive to get.

    Instead of putting the pictures in the cloud I wanted to put them on a scan disk just in case something happens to my computer or house. Almost all of them fit on the disk. Plus they were on sale at a great price.

    Wrote all of my files (several GB) in a very quick manner and reads them almost instantly, compared to a hard drive that would have to take me a few extra seconds. Pretty good overall and I'd probably buy another one of these if I had to.
