WD My Book 22TB Desktop External HDD Review

Massive desktop backup capacity with password protection, hardware encryption and backup-focused software for large personal data collections.

22TB Desktop HDD USB 3.2 Gen 1 256-bit AES Encryption 3-Year Warranty

What It Is

The WD My Book 22TB is a high-capacity desktop external hard drive designed around local storage and backup. It provides substantially more capacity than portable drives while adding security and backup-oriented features beyond a basic external HDD.

The WDBBGB0220HBK-NESN combines 22TB of storage with USB 3.2 Gen 1 connectivity, password protection, 256-bit AES hardware encryption, device-management and backup software, and out-of-box Windows and Mac compatibility through exFAT formatting.

Rockin Box Tech perspective: My Book makes the most sense for consumers who want huge directly attached storage but also value password protection, hardware encryption and backup-oriented software. It sits between a basic desktop external drive and the greater complexity of a multi-drive NAS.

Why My Book Is More Than Basic Bulk Storage

22TB Capacity

Twenty-two terabytes provides enormous room for computer backups, photographs, video collections and other data-heavy libraries.

Hardware Encryption

WD supports password protection backed by 256-bit AES hardware encryption, providing a meaningful security feature for a drive that may contain years of personal data.

Backup-Oriented Software

Included downloadable software supports device management and backup, giving My Book a more backup-focused feature set than a basic external storage enclosure.

Windows & Mac Ready

Current My Book models ship formatted as exFAT for immediate compatibility with supported Windows and macOS systems.

Direct-Attached Simplicity

Consumers get massive local storage without configuring a network, user accounts, storage pools or a dedicated NAS operating system.

Three-Year Warranty

WD backs the current My Book family with a three-year limited warranty, one year longer than the current WD Elements Desktop warranty.

What Consumers Are Saying

Consumer feedback remains part of the Rockin Box Tech selection process, but this exact model requires an important qualification. The 22TB WDBBGB0220HBK-NESN currently has very little direct retailer review history compared with older and smaller-capacity My Book models.

Exact-SKU Feedback Is Limited

The exact 22TB model does not currently have enough direct Best Buy customer reviews to support meaningful conclusions about long-term owner satisfaction.

Capacity Is the Main Attraction

The product's strongest consumer proposition is straightforward: 22TB provides far more local backup room than mainstream portable drives without requiring a multi-bay storage system.

Security Adds Value

Password protection and hardware encryption distinguish My Book from simpler bulk-storage products when consumers intend to keep sensitive personal files on the drive.

At the time of this research, Best Buy lists zero customer reviews for the exact 22TB WDBBGB0220HBK-NESN. Rockin Box Tech therefore does not assign this model an owner-satisfaction conclusion based on that retailer. Consumer review availability and totals can change over time.

WD My Book vs WD Elements Desktop

Why Choose My Book?

22TB high-capacity storage
Password protection
256-bit AES hardware encryption
Backup and device-management software
Three-year limited warranty
Out-of-box Windows and Mac compatibility

Why Choose WD Elements?

Simpler bulk-storage design
Good choice when advanced security is unnecessary
Straightforward direct-attached storage
May provide better value depending on current pricing
Useful for basic backup and media archives

Where 22TB Makes Sense

Whole-PC Backups

The capacity can accommodate large computer backups and multiple backup generations depending on the software and retention settings being used.

Photo & Video Libraries

High-resolution photos and video can consume terabytes quickly. Twenty-two terabytes provides significant room for growing personal or creative archives.

Protected Personal Archives

Hardware encryption and password protection make My Book more attractive when large local archives include personal, financial or otherwise sensitive files.

Strengths & Limitations

Strengths

Huge 22TB capacity
256-bit AES hardware encryption
Password protection
Backup and device-management software
Windows and Mac compatibility
Three-year limited warranty
Simple direct USB connection
Lower cost per terabyte than equivalent SSD storage

Limitations

Requires external AC power
Much slower than modern external SSDs
Not intended as a portable travel drive
No built-in network access like a NAS
Mechanical storage remains vulnerable to drive failure
Exact 22TB SKU currently lacks a substantial review sample
One large drive should never be the only copy of important data

Works Best With

High-Capacity Home Backup

A strong fit for desktops and workstations containing several terabytes of files that need a large local backup destination.

Large Media Collections

Particularly useful for photography, video, music and other collections where storage requirements continue growing over time.

Security-Conscious Storage

Password protection and hardware encryption add value for users who want more protection than a basic external HDD provides.

Backup Reality Check

A 22TB drive can hold an enormous percentage of a person's digital life, which makes redundancy even more important. My Book should not contain the only copy of irreplaceable data. Important files should exist on another independent device or location, and at least one backup should ideally be isolated from the primary computer.

Rockin Box Tech Summary

The WD My Book 22TB is a high-capacity local backup device with a stronger security and software package than a basic desktop external hard drive. Its 22TB capacity is the headline feature, but password protection and 256-bit AES hardware encryption help distinguish it from simpler bulk-storage alternatives.

Compared with WD Elements Desktop, My Book is the more backup-focused option. Compared with a NAS, it is dramatically simpler: connect it directly to a computer, configure the desired backup method and use it without maintaining a network-storage platform.

The biggest caution in our current research is not a documented product defect—it is the limited owner-feedback sample for this exact 22TB SKU. That means our assessment relies more heavily on WD's verified specifications and the product's feature set than on broad exact-model customer sentiment.
