Pros & Cons

Pros

✓ Two RAID-optimized WD Red drives inside, not desktop-grade spares
✓ Up to 360 MB/s sequential reads over USB Type-C
✓ Switchable between RAID-0, RAID-1 mirroring, and JBOD
✓ Two USB Type-A hub ports for chaining accessories
✓ All cables included; works back to USB 3.0 and 2.0

Cons

✗ Ships in RAID-0, so one drive failure loses everything
✗ RAID-1 mirroring halves the 16 TB to 8 TB usable
✗ NTFS-formatted, so Mac users must reformat first
✗ Desktop enclosure needs AC power, not bus-powered

Manufacturer description

WD's My Book Duo puts two RAID-optimized WD Red drives behind a single USB Type-C cable, and this 16 TB Western Digital configuration is aimed at people whose photo, video, and project libraries have outgrown internal storage. Out of the box it ships in RAID-0 for maximum speed and usable capacity, with sequential reads rated up to 360 MB/s over USB 3.1 Gen 1. If you would rather trade capacity for safety, WD Drive Utilities lets you reconfigure the enclosure to RAID-1 mirroring or split it into two independent JBOD volumes, so the same box can serve as a fast scratch drive or a redundant…

SpecPicks Verdict

SpecPicks scored WD 16 TB My Book Duo Desktop RAID USB 3.1 External Hard Drive and… 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.

Frequently Asked Questions

How much usable space do I get from the 16 TB model?

In the default RAID-0 mode you get the full 16 TB as one volume. Switch to RAID-1 mirroring and usable capacity drops to 8 TB, since the second drive holds a copy of the first.

Can I change the RAID mode after I buy it?

Yes. The included WD Drive Utilities software reconfigures the enclosure between RAID-0 (default, max speed and capacity), RAID-1 (data mirroring), or JBOD, where the two disks appear as independent drives.

How fast is it in real use?

WD rates the My Book Duo at up to 360 MB/s sequential read when connected through the USB Type-C port, thanks to the WD Red drives inside. Actual speeds depend on your port, cable, and file sizes.

Does it work with a Mac?

It ships formatted NTFS for Windows 10, Windows 7, or Windows Vista, so you will need to reformat it for macOS before use. Reformatting erases the drive, so do it before copying data over.

What kind of drives are inside, and is it rated well?

Western Digital uses RAID-optimized WD Red drives with firmware that auto-manages drive operations for read/write data integrity. Buyers generally rate this model well.
