HDD Western Digital 20 TB Desktop My Book Duo

The My Book™ Duo desktop drive offers high-capacity external storage for photos, videos, documents and music. It ships configured in RAID‑0 for maximum sequential performance and can be reconfigured to RAID‑1 for data redundancy or to JBOD for use as two independent volumes. The unit includes a USB Type‑C port with all necessary cables and two USB‑A hub ports for connecting additional accessories, and supports USB 3.1 Gen 1/3.0/2.0.

Advantages

The drive provides very large capacity options up to 20TB in a single enclosure and delivers up to 360 MB/s sequential read speeds when using the USB Type‑C connection in RAID‑0. It is supplied with RAID‑optimized WD Red™ drives featuring firmware tuned for two‑disk arrays to help maintain read/write data integrity. All cables are included for plug‑and‑play connectivity and the bundled WD Drive Utilities™ software allows reconfiguration between RAID‑0, RAID‑1 and JBOD modes.

How to use

Connect the My Book™ Duo to your computer using the included USB Type‑C cable (or the appropriate USB adapter). The drive is ready to use in RAID‑0 out of the box for maximum performance; run the included WD Drive Utilities™ software to change configuration to RAID‑1 for mirrored redundancy or to JBOD to use drives independently. Use the two USB‑A hub ports to attach peripherals or additional accessories. Follow your operating system’s prompts to format or assign drive letters if required.

Recommendations

For best performance with large sequential transfers (video editing, bulk backups), keep the drive configured in RAID‑0 and connect via the USB Type‑C port. Switch to RAID‑1 when redundancy is required to protect irreplaceable data. Regularly update and use the WD Drive Utilities™ software to manage drive health and perform diagnostics.
