Wd Blue 500gb Desktop Hard Disk Drive Wd5000 3.5inch

Good value! Western Digital has been my primary source of disk drives and have never been disappointed in them. They seem to last for years! I was surprised to discover I was unable to use this one as an external drive connected via an Interface Cable to a USB Port; I have a couple 2.5" drives I do that with. Finally decided to purchase an Interface Cable with a Power Supply and that did the trick!
