I was looking for an external hard drive to free up space on my laptop. I found this on Amazon. It is advertised as shock and water resistant. This is a plus, as i plan to use it to bring photos to a family reunion. I haven't tested this aspect, but the construction feels solid with silicon corners. There is a short video on the amazon product page. The 1Tb ends up being about 970gb. It is fast! I transferred over 40,000 files in less than 20 minutes. It comes with a short 3.0 USB cord that clips around the edge of the hard drive for convenient carry. So far, I love it!
