    This flash drive had everything promised on it. So this is primarily an assessment of the work done to produce it, not of the piece of hardware itself.

    For the cost it was pretty good. Wife just needed a new one for her art work to store. The read write speed is "ok" but that is understandable because of the price and that it's BestBuy, their equipment isn't the best. They are meant for good equipment at affordable prices. If you want a VERY fast USB drive, use Newegg and expect to pay some for it.
