    I've been looking for a new 2TB external hard drive and I've run across some 2TB externals that are 2 x 1TB. Is there a benefit of going this route or would getting a solid 2TB be better?

    2x1TB will give you an option of RAID 0 and RAID 1. RAID 0 is useless unless you use something else than USB or FW800 and for most people, RAID 1 isn't useful either. A regular 2TB is better choice since there should be no need for a fan and the possibility of a failure is always lower when there is only one drive.

    There is no inherent advantage to either strategy. The most important factor when comparing like hard drives is the warranty. No platter-based drive is more reliable than any other, so buy the one with the best warranty for the capacity you want and your budget.
