    I purchased this for my internship because I needed a locked storage device. I couldn’t figure out how to use the encryption feature. The software that you needed never downloaded properly to work. I got frustrated after a few attempts and ended up getting something else and just using this as a regular flash drive.

    Works just as I thought, was tricky on the PS4 though, you have to push a little more than it feels like you should.

    Takes a while to get used to using the keyboard. Once you've used it for awhile has great possibilities.

    I wanted a drive that I could just password protect - something that contained a software program would allow me to just set password and access levels - What this does is it totally encripts all data being transferred to it and this takes a really long time both going in and going out - I really didn't need that level of security - otherwise it is another 64 gig drive -
