Review on USB Flash Drive For IPhone Photo Stick 1TB Memory Stick USB 3 by Kyle Robinson

These so-called mass storage devices are extremely slow and faulty. If you try to throw folders into the device it will copy eons and then if they are supposed to be copied and you try to open the folder it says the folder is empty. It took ten, ten hours to try to transfer 500 gigs to one of these things and when it "done" all the folders were empty.
