The drive is dual-interface, with USB 3.0 and offers two Thunderbolt ports. Thunderbolt and USB 3.0 cables are included.

Six models are available. The enclosure alone retails for $300. A model with two 1TB drives retails for $429. A pair of 2TB drives sells for $495. A pair of 2TB Hybrid drives installed in the case sells for $580. A pair of 3TB and a pair of 4TB drives pre-installed costs $575 and $760 respectively.

    That's $190 extra for the TB-1 interface and a TB cable ($32 for 1m black cable). Does it really cost that much more for the TB interface hardware and license fee? It's only TB-1 as well. They removed Firewire 800 (keeping USB3.0) so subtract the cost of the FW800 hardware and it's still a big chunk of money.

    Did some research. The new Mac Pro uses two Intel DSL5520 TB controllers, each retailing for $9.95, so basically $20 on the Mac Pro end to add TB-2 (plus two jacks). iFixit talks about an L129NB11 EFL as possibly being the TB controller in the Apple TB Display but there isn't any manufacturer information about it or confirmation that it actually is the controller. Assuming the TB controller would be the same on external devices (bad assumption), I'm still trying to figure out why vendors add so much more than the cost of the component.
