enterprise hard drive as an extra external drive-any problem with this idea

I have heard that enterprise hard drives are more reliable than the standard hard drives in retail or consumer computers. I want to get an external hard drive for extra storage and backup purposes. My desktop and notebooks are the typical computers that are sold to retail customers. Will there be any problems having it access and drive an enterprise hard drive in an external hard drive case? I am thinking to get a fairly large size around 1T so I figure it would have its own power supply and not be powered by the USB drive. Data access will probably be via USB and/or eSata.
