    This is a great little thumb drive. Priced well with adequate body strength, and includes a neat, though tiny labeling space. Great Western Digital San Disk quality as well.

    This memory stick is tiny but it holds up to 128GB! No regrets whatsoever. Since it has USB 3.0 it is super fast too. It's an amazing memory stick for storing lots of important files.

    Needed a high capacity thumb drive for hi-Rez music files and this one fits the bill. High capacity, USB 3.0 compatible, and an unbeatable price makes this one a no-brainier.

  • 128G Thumb Drive

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I was filling up my 64G backup thumb drives. Using a 128G one makes it much easier for me to keep track and archive my backup files. The big tipping point was the price on these 128G drives. I do not need blazing speed for my planned usage, but so far I have had nothing to complain about after loading over 55G of data (mostly video files).
