COOLMAX 3.5" X-Treme
 

Having previously looked at the 2.5" X-TREME Files, I was pondering which one would someone choose, and for what reasons. I think you should take a look at this one, and decide. I'll of course link to the 2.5" review, if you hadn't seen it, or don't remember it. Overall, this is an easy way to back up your files with a touch of a button. Come see what I like, and don't like about this.
