Move data at unprecedented speeds—Do more work in less time with ground-
breaking data transfer speeds using Thunderbolt technology. Your My Book Thunderbolt
Duo dual-drive storage device provides a fast way to get information to and from your
external drives.
Multiple dual-drive storage configurations—Select RAID or Individual Drives modes:
• RAID 0 (Striped mode) for maximum capacity and accelerated performance.
• RAID 1 (Mirrored mode) for double-safe data protection by automatically creating
a second copy of your data. One of the drives stores your data and the other drive
saves a second copy. If either drive fails, your data is protected because it is
duplicated on the other drive.
• JBOD (Individual Drives mode) for using the two drives independently, and not
configured into a RAID array.
Enhance workflow efficiency—Use the two Thunderbolt ports to daisy chain up to six
Thunderbolt storage devices to achieve maximum workflow efficiency and productivity.
High-speed multitasking—The revolutionary bidirectional Thunderbolt technology
delivers unmatched speed for multitasking projects.
Super-fast external boot capability—For information about using your My Book
Thunderbolt Duo as an external boot device using Mac OS X 10.6.8 or later, see the
Apple Support article at http://support.apple.com/kb/HT4718 or http://

yourself. No tools are needed.
