Excerpt: The extra security software is a nice add-on if you need to lock your data. I'll use mine just to transfer/backup files. I attached mine to an extender cable that inserts much easier into the USB port. I use it on Linux & Windows XP/7.
Excerpt: This usb storage strive serves its primary purpose. It works and has nice storage capacity. It is too thin and light for my liking. I also bought a Sandisk slider unit with the same storage capacity that I prefer. This slider unit has a slide design that protects the usb head without having to deal with a cap. The Sandisk slider unit is also fatter and allows for a better grip when trying to either insert or remove the unit from the computer.
Summary: If you were transferring a file, it wouldn't play nice if you continued to look through other folders of the drive. It would pretend that it wasn't "responding" and looks like it would freeze. However, if you just let it do it's transfer, it'd be fine. Even when it pretended to freeze (and I say pretend because...) it would still continue to transfer anyway and no harm done.
Pros: This drive is small, convenient, and has quite a bit of memory (I had upgraded from a 4gb). I feel like the end is more protected because it is a switch model and the plug is tucked away. It's easy to stick it in your pocket and not be worried about bending and/or breaking anything.
Cons: The body is all plastic. It had me worried at first, like it could snap at any moment, but I felt more comfortable the more I handled it.
