Cons
- ✗ RAID-0 default means one drive failure loses the entire 44TB volume

Manufacturer description
The WD My Book Duo packs 44TB of desktop storage into a single dual-drive enclosure, making it a serious archive target for photo libraries, 4K video projects, and full system backups that long ago outgrew a portable drive. Western Digital ships it configured in RAID-0 out of the box, so both drives present as one large volume for maximum capacity and throughput, and you can reconfigure the array if you'd rather trade capacity for redundancy. Connectivity is USB 3.1 Gen 1, with backward compatibility down to USB 3.0 and USB 2.0 and all cables included, so it drops onto an existing desktop…
SpecPicks Verdict
SpecPicks scored WD 44TB 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. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
How much usable space do you actually get with 44TB?
In the default RAID-0 configuration all 44TB is presented as a single volume. If you switch it to RAID-1 for redundancy you get roughly half that, around 22TB, since the data is mirrored across both drives.
Is the My Book Duo safe for backups if a drive fails?
Not in its shipped state. It arrives RAID-0 ready, which stripes data across both drives with no redundancy, so a single drive failure takes the whole volume. Reconfigure it to RAID-1 if fault tolerance matters more than capacity.
Does it work with a Mac?
It connects over USB 3.1 Gen 1 and is backward compatible with USB 3.0 and USB 2.0, so it will connect to any modern Mac. Drives in this family typically ship formatted for Windows, so check the listing for the shipping format and reformat if needed.
What does the password protection actually do?
The enclosure includes 256-bit AES hardware encryption paired with password protection, so the contents are encrypted on the drive itself rather than by software running on your computer. Without the password the data is not readable on another machine.
Do I lose a USB port on my computer by adding this drive?
Effectively no. The enclosure includes two USB 3.0 Type-A hub ports, so you can plug a card reader, flash drive, or peripheral into the My Book Duo itself and end up with more usable ports than you started with.
