Pros & Cons

Pros

  • ✓ 24TB of usable capacity in RAID-0 straight out of the box, no setup needed
  • ✓ WD Red NAS-class drives inside, not desktop-grade mechanisms
  • ✓ Up to 360MB/s sequential reads over USB Type-C per Western Digital
  • ✓ 256-bit AES hardware encryption with password protection built in
  • ✓ Two USB 3.0 Type-A hub ports free up connections on your computer

Cons

  • ✗ Ships in RAID-0, so a single drive failure loses the entire 24TB volume
  • ✗ Desktop enclosure needs external AC power, not bus-powered or portable
  • ✗ USB 3.1 Gen 1 caps at 5Gb/s, below what a two-drive RAID-0 could saturate
  • ✗ Two-bay design offers no RAID-5 option, only mirroring or striping

Manufacturer description

The My Book Duo puts 24TB of Western Digital storage on your desk in a two-bay RAID enclosure, shipping in RAID-0 for maximum capacity and sequential throughput. Inside are WD Red drives, the same NAS-class mechanisms Western Digital rates for sustained multi-drive workloads, and Western Digital quotes sequential reads up to 360MB/s over the USB Type-C connection. That makes it a practical target for offloading a photo library, a growing 4K video archive, or a full system image rather than juggling several smaller portable drives. Connectivity is USB 3.1 Gen 1 with backward compatibility to…

SpecPicks Verdict

SpecPicks scored Western Digital 24TB 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

Is the My Book Duo set up as RAID 0 or RAID 1 out of the box?

It ships RAID-0 ready, which stripes both drives for the full 24TB and the highest sequential speed. You can reconfigure to RAID-1 mirroring, which halves usable capacity to 12TB but survives one drive failure.

How fast is this drive in real use?

Western Digital rates it at up to 360MB/s sequential read using the USB Type-C port. Actual speeds depend on your host port, cable, and whether you are moving large video files or many small ones.

What drives are inside the enclosure?

Western Digital Red drives, the line built for multi-drive and NAS duty rather than single-drive desktop use. The enclosure is user-serviceable, so drives can be accessed if one needs replacing.

Will it work with my computer's USB ports?

Yes. It is USB 3.1 Gen 1-ready with USB 3.0 and 2.0 compatibility, and all required cables are included. Older ports work but will limit transfer speed.

How is the data protected if the drive is stolen?

The enclosure uses 256-bit AES hardware encryption with password protection, so the volume cannot be read without your password. Keep that password recorded somewhere safe, as there is no bypass.
