WDC My Book Thunderbolt Duo Drive Pricing and Shipping Announced

duo2
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.

In other words, ordering a new Mac now works much like ordering an...

Insert obligatory series of posts:

(average Mac user) LOL this is ridiculous who would pay that. Why do we even have TB ports. Apple is greedy
(person representing 0.3% of market) PROs do, you wouldn't know that though because all you do is use fb
(more informed Mac user) Actually Intel is being greedy because of licensing

Love the potential Thunderbolt has, but the price is just horrific for the products that use it.

Was hoping that this year we'd see more consumer friendly prices for Thunderbolt accessories.

Negatory Ghost rider, your condescending-ometer is way off. Anybody in businesses will use one of the many, faster enterprise solutions available to them. This is cheaply made end-user swill with no redeeming value. :D Smaller companies will be much better served by one of the many cheap cloud options available to them.

Cant believe cloud options were just used in a conversation about saving time.

Still shocked your trying to talk to me about things you don't understand :D.

Wow really? You claimed no drive was worth over $100/TB regardless of how much time it saved you. I provided a logical case where saving time is of huge value. Where up front cost of a faster storage solution is easily offset. You proceeded to be a douchebag. Go try and impress someone else with your BS.

Was really hoping these guys would be the start of more affordable TB drives; shame that’s not the case. I can buy 4TB worth of firewire drives for less than half of that price. Sure the transfer rates are amazing but as long as the pricetag stays high, sales will stay low.
Seems that's the point though, no? If you're not looking for high performance or RAID, thunderbolt won't help you that much. You'll hit the single non-ssd drive bottleneck first, no?

Yes, be a jerk on the internet. That will make you feel excellent about yourself. It may even get you layed if you brag of such exploits in the local drinking establishment.

I think he has a valid point. If you are in any sort of professional environment time is money. In a hypothetical situation having to wait 4 hours vs having to wait 1 hour is a huge difference, and repeated frequently the time savings would easily pay for the added cost.

So really your angry overreaction to his comment made you look like more of a jerk.
