The WD My Book Duo 28TB USB 3.0 RAID Array features two 3.5" drive bays that each sport a 14TB hard drive to provide a total capacity of 28TB 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, plus a USB 3.0 Type-C to Type-C cable and a USB 3.0 Type-C to Type-A cable. 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 Type-A 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.
The My Book Duo drive provides 28TB 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.
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.
