    I've found SanDisk flash drives to be the most reliable on the market. I've never had formatting problems like on some other brands. And the SanDisk drives are durable, no matter how many times you use them.

    The Sandisk thumb drive is a reasonably priced fairly well built, good quality instant access device to carry programs in your pocket. Also great for storage for data recovery in end user support, as well as simply storing pictures, documents and music etc for every day use. The 256Gb is about $30.
