Seagate FreeAgent Pro 750GB External Hard Drive
 

The five year warranty is another key selling point on the FreeAgent Pro. While you could easily add a Seagate drive (with its own 5 year warranty) to any old enclosure, Seagate has bundled the whole thing together for you, thrown in some useful software, and then applied their industry leading warranty to the whole thing.
