    SanDisk - Ultra 512GB USB 3.0 Flash Drive - Black

    I bought this USB flash drive to expand storage on my Insignia Fire TV. (Found out later that the TV accepts a maximum of 64GB for flash drive expansion.) I'm now using this 512GB flash drive to back up my laptop. Really fast, small and convenient. Highly recommend!!
