    It's a thumbdrive. It works as intended. Write speeds for small files will be close to 100mb/s, bigger files it eventually drops to about 30mb/s

    I only gave 4 stars because I really wish there was a way to store your photos in chronological order. I am happy that it at least keeps the date and time stamp but I want them to be better organized. I don’t think this is a fault of Sandisk, I believe they all function like that.
