I'm looking at getting a 1TB external hard drive. I found these two on Amazon... http://www.amazon.com/Toshiba-Canvi...9883&sr=8-1&keywords=1+tb+external+hard+drive http://www.amazon.com/Elements-Port...9883&sr=8-3&keywords=1+tb+external+hard+drive The WD hard drive (2nd link) is $5 cheaper. I've always used WD external drives and have never had an issue. Is there any real difference here? Benefit of one over the other? Or maybe a different drive that's even cheaper that I haven't found?
