    I’ve had SanDisk products in the past including flash drives like this one and they’ve all worked well. The reason I bought this specific flash drive was it’s large data capacity. I can probably back up almost all the important files on my computer with this flash drive. It’s convenient for storage or transfer from one computer to another.
