As higher and higher capacity drives are released into the market, we slowly see the latest trickle down into enclosures. The My Book lineup is no stranger to this process as in the past it has taken advantage of the entire WD product lineup. With this latest iteration of the My Book Duo, WD has moved this platform over to USB-C connectivity while increasing capacity with the use of their new 10TB WD Red drives. From the factory, the Duo is RAID 0 ready, but does support RAID 1 and includes a host of software including WD Backup and WD Security for hardware-based 256-bit encryption. Compatibility includes Windows 7+ out of the box while other operating systems will require a reformat. The MSRP of the 20TB My Book Duo is $799.99 with a three-year warranty.
