    It comes with encryption software so that you can password protect your files. I leave this in my computer back pack so if it gets stolen at least our personal files are secure. Got it on sale for $25!!!

    Decent write speed. I transferred a large quantity of video files onto the flash drive and I was probably averaging 25 MB/s or so.

    my files were downloaded on the usb, a password was setup and now the password does not work. I cannot get in to the files, very upset. I know it is a good tool but for the password issue it is frustrating. if you know of a solution I would gladly appreciate it.

    I have 8+ of Scandisk USB flash Drives 2.0 and 3.0. Have never had a problem with them. Don't let the flimsy plastic grasp fool you, they are sturdy and come with a 5 year guarantee when you register them.

    Good drive overall, but two caveats; First, it won't work with older versions of Windows for some reason. Second, it has a bundle of unneeded/unwanted aps preloaded which try to activate when you plug it in for the first time. Harmless (probably) but annoying adware and promoware I had to axe. Note to Sandisk: When I want your help, I'll ask.

    You can never go wrong purchasing a SanDisk product. I have multiple SanDisk products and all are amazingly dependable. Even when I can buy a similar product at less cost, I continue to buy SanDisk.
