WDC My Book Thunderbolt Duo Drive Pricing and Shipping Announced

At Macworld 2012, we highlighted the newly announced My Book Thunderbolt Duo drive from WDC. Each drive enclosure held two hard drives in a RAID configuration and offered two Thunderbolt ports. The units could then be daisy chained together over Thunderbolt to create a single high performance logical drive.
WDC has since announced shipping and availability of the new drive systems.
The new My Book Thunderbolt Duo provides professionals and Mac® enthusiasts with five primary areas of performance, double-safe data protection and flexibility; ultra-fast data transfer rates for greater work efficiency; a 4 TB/6 TB large-capacity; customized dual-drive storage system with RAID 0, 1 and JBOD options; customer serviceable drives; and dual Thunderbolt ports for daisy-chaining multiple My Book Thunderbolt Duo devices or other peripherals.
Pricing for the new enclosures has been set at $599.99 USD MSRP (4 TB) and $699.99 (6 TB) and are available online.
To compare, the Thunderbolt version seems to carry a $200 premium over their My Book Studio Edition II drive system which provides a similar setup (4TB/$399, 6TB/$499), though without Thunderbolt performance and connectivity.
