    Bought this as a backup to my music collection. I pretty much stick to SanDisk for solid state storage like this due to their super low failure rate. USB 3 speeds are amazing.

    I lost my old drive ... it was devastating ... losing 3 years of my life ... this new drive has some added security features I like and is super fast. Just wish I hadn't lost all the information on my old one.

    in term of storage this gets the job done, but it is a shame how they keep doing this USB sticks so big, there is no need to basically make them this big, for the price you can probably find something more small and practical

    Good buy. No activity light.

    I bought the exact same model a year ago at the same price. They both perform the same - 100 MB/sec read, 30 MB/sec write. The one from last year has an activity light. This one doesn't. I thought it was defective, and exchanged it for another one. The second one doesn't have a light either. This is minor, but it shows how the product is being cheapened over the year. I knocked off one star for this.

    This Ultra flash drive is able to transfer data at sustained rates, unlike some cheaper drives. Costs a few dollars more, but worth it when transferring large files or large amounts of data!

    Works perfectly. I bought this thumb drive to put information about video conferences. I like that you can add a password so tha all information remains confidential.
