Does anyone know if this external HD is good? http://www.amazon.com/gp/product/ref=pe_59010_14899260_pe_i3/B001D7REJ4 More than anything else, reliability is the issue. Space is good, transfer speed is fine for what it will be used for, the only real question is, does this brand (or specific HD) have a good track record of not failing? Or, I guess another question would be, is there a better buy for the same $? Thanks for the help!
