Is the extra cost of them there simply to cover the cost of longer warranty that these drives have?

Not talking about RPM speed or cache that makes one hard drive clearly "better" than the other.
What is physically different in manufacturer's elite line of hard drives, be it from WD or other manufacturers?

What in the manufacturing process makes it so that these drives can be considered more reliable than the lower priced line of hard drives?

My guess would be that it's not so much the manufacturing process as it is some superior components. The newer "z" model blacks have twin processors that supposedly make them faster as well.

Extra g-force sensors for a more elaborate method of rotational vibrational sensing? (http://www.wdc.com/wdproducts/library/other/2579-001079.pdf). HGST mentions the latter as a difference between its DeskStar and UltraStar models.

A second CPU for handling the cache better? Here's a review that shows random writes being about twice as fast for WD Black, Seagate Barrracuda XT, and HGST 7K3000, than for other drives: http://media.bestofmicro.com/E/3/362091/original/h2benchw_access_write.png

Is the spindle fastened at the top with a screw that goes through the lid?
