The WD My Book Duo 20TB USB 3.0 RAID Array features two 3.5" drive bays that each sport a 10TB hard drive to provide a total capacity of 20TB for USB Type-C and USB Type-A systems. The two included hard drives are WD Red drives designed for high-performance and reliability. WD has configured the drives in RAID 0 and lets you reconfigure them in RAID 1 or JBOD, using the included WD Drive Utilities software program. The My Book Duo comes with a USB 3.0 Type-C port along with two USB cables that allow you to connect to a typical USB port or a reversible USB Type-C port on the host system. With RAID 0 and USB 3.0 technology, the My Book Duo delivers sequential read speeds of up to 360 MB/s.

Other notable features include a 2-port USB 3.0 hub, which expands the host system's connections, and AES hardware encryption that helps prevent unauthorized access to sensitive data. In addition, the My Book Duo is pre-formatted in NTFS for Windows systems and requires a reformat for use with Mac.

Capacity
The My Book Duo drive provides 20TB of storage capacity with a single connection. This amount of digital storage space lets you hold and back up your photos, videos, documents, and songs.
RAID 0
The My Book Duo is preconfigured in a RAID 0 array that grants maximum speed and capacity. Utilizing the included WD Drive Utilities software, you can reconfigure the drives in a RAID 1 for redundancy or JBOD array as two independent drives.
WD Red Drives
Two WD Red drives are included to provide high-speed and reliable storage. To help ensure read/write cycle data integrity, RAID-optimized firmware is suitable for a two-disk array system with auto management of drive operations.
Compatibility
With the included USB Type-C to Type-C and USB Type-C to Type-A cables, the My Book Duo supports a wide-variety of systems.
Two-Port USB 3.0 Hub
The My Book Duo drive can serve as a quasi-docking station with two USB 3.0 Type-A ports designed for accessories, such as an additional storage device, keyboard and mouse set, card reader, and mobile devices.
Encryption
The My Book Duo drive comes with 256-bit AES hardware encryption with WD Security software built in to help keep private content secure. You can set a personalized password to activate hardware encryption and data protection.

COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
