The My Book Thunderbolt Duo, which we've already reviewed, is WD's first Thunderbolt storage device. So far it's been the most affordable Thunderbolt storage device on the market in terms of cost per gigabyte. The new 8TB-capacity drive follows that tradition with a price of just $850, and it now comes with a Thunderbolt cable included.

The drive comes with two internal hard drives that are user-serviceable and can be set up in RAID 0 (default) or RAID 1 configurations. The My Book Thunderbolt Duo generally offers lots of storage space and decent performance. For much faster performance, WD has the higher-end My Book VelocityRaptor Duo with just 2GB of storage space.

WD also announced today a new My Book 4TB external hard drive. This is a single-volume external hard drive that supports USB 3.0 and costs $250.
