Manufacturer description
The Western Digital My Book Duo packs 20TB of desktop storage into a single enclosure, using two WD Red drives configured in RAID-0 out of the box. That striped setup is what pushes sequential reads up to 360MB/s per Western Digital's own figures, so pulling a folder of 4K footage or a decade of RAW photos off the drive doesn't stall your workflow. Connectivity is USB 3.1 Gen 1, with backward compatibility down to USB 3.0 and 2.0, and cables are included. Two USB Type-A hub ports on the enclosure let you daisy-chain a card reader, a smaller portable drive, or a keyboard without hunting for…
SpecPicks Verdict
SpecPicks scored Western Digital 20TB My Book Duo Desktop RAID External Hard Drive HDD using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Western Digital's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Is the My Book Duo already set up as RAID, or do I configure it myself?
It ships RAID-0 ready out of the box, so it presents as a single 20TB volume with no setup. You can reconfigure it through WD's software if you prefer a different mode.
How fast is the 20TB My Book Duo?
Western Digital rates it at up to 360MB/s sequential read, achieved with the WD Red drives inside over the USB Type-C port. Actual speed varies with file size and host port.
What drives are inside this enclosure?
Western Digital lists WD Red drives inside the My Book Duo, which is what the 360MB/s sequential read figure is based on.
Can I plug it into an older USB port?
Yes. It is USB 3.1 Gen 1-ready and compatible with USB 3.0, and Western Digital lists USB 2.0 support as well. Older ports will run at their own slower speeds.
Does it protect my data if someone takes the drive?
It includes 256-bit AES hardware encryption and password protection, so the volume stays locked without your password. Check the product listing for current warranty terms.
