We got to know these HDDs in January, when they were presented at the Consumer Electronic Show 2012. At the fair, we learned that the new drives have two Thunderbolt ports, thus allowing threads. Despite this, no information on price / availability had been commented on.
Now, they have arrived. The HDDs of the My Book Thunderbolt Duo line can be configured as RAID 0, RAID 1 or as JBOD. They already leave the factory formatted for use with Macs (HFS + Journaled), compatible with Apple's backup tool, Time Machine.
Comparatively, they are far superior to the My Book Studio Edition II line, which offers FireWire and USB 2.0 connectivity. The new Thunderbolt HDDs offer transfer rates of up to 10Gbps, while not My Book Studio Edition II, the maximum speed of 480Mbps. The difference in performance is also reflected in the price: the versions with 4TB and 6TB of capacity of the new line cost US $ 600 and US $ 700 respectively, they can be purchased through the manufacturer's website and do not accompany the cable, which costs R $ 150 at Apple Online Store.
It remains to be seen whether high performance is worth the investment depending on the user's profile, certainly it is.
