Those things are pretty much a commodity these days, especially with such small capacity. Does your computer have USB 3 ports? If yes and you are storing a lot of media it's probably worth going for the USB 3 drive.

I've been using a 128GB USB 3 drive as my photo backup when I am on the road and it's worked out very well. Certainly better than a bigger hard drive.

Generally SanDisk has a very good reputation. I'd probably read reviews to see if whatever one I am planning to buy has any documented issues. When it comes to this sort of thing I usually start with Newegg.com or Amazon.
