Summary: I have been using this disk as a backup drive for a couple years. It does its job very well. No need of external power supply, just plug it into a USB port and you are ready to go. Drive has been very reliable so far.
Summary: I purchased this item several years ago because the one I had got fried. This USB powered device removes the need for cables and provides sufficient space for any data you may need to travel with you. It has a nice sleek design with a tough case.
