    The price advertised attracted me. I read the specifications for this flash drive and compared them to the need expressed to safeguard pictures on a computer I was transferring information from to a new computer. It works well.

    Flash drives are great for grabbing files on the go and moving info between computers. Sandisk has been my go-to flash for years and this 64gb version does not disappoint. Easy software for encryption and password protect as well.

    I have bought well over 50 flash drives in the fast few years, and while this one is not one of the super fast USB 3.0 ones, it is still a good drive with good transfer rates. For the price and capacity, it is a great buy.
