    Awesome Features

    This expansion drive is everything that it is made out to be. While having the capacity to store all our files it is fast and easy to use. Would definitely purchase another.

    Seagate to the rescue

    My 2 TB told me it was full of data so I needed to down load all the images onto my new 4 TB and this turned out to be a very easy operation. Now I can keep adding more images as time goes on.
