⭐ Pros — What This Drive Does Well
🗃️ Huge 4 TB Storage Capacity
4 TB gives you plenty of space for large backups, 4K videos, games, media collections, and even full system images — perfect for desktop backup tasks.
🔐 Built-In Security Features
Unlike basic external drives, the My Book includes 256-bit AES hardware encryption with password protection — a big plus for protecting sensitive personal or business data.
🛡️ Automatic Backup Options
WD Backup software (and Time Machine compatibility for Mac) lets you schedule regular backups, so your files are saved automatically.
💼 Desktop-Style Reliability
Designed as a permanent desktop storage companion, the My Book is built to hold large amounts of data reliably over time — ideal for home offices or workstations.
💾 Plug-and-Play Setup
Out of the box, it’s preformatted (exFAT) and ready to work with both Windows and Mac, though you might reformat if needed for Time Machine or specific workflows.
⚠️ Cons — Things to Consider
🐢 Not the Most Portable Option
This is a desktop 3.5″ drive that requires a power adapter — not ideal if you need storage to carry around with a laptop.
📈 Speed Limited by HDD Technology
USB 3.0 provides decent throughput, but as a traditional spinning HDD, real-world transfer rates are slower (typically in the tens of MB/s range) compared to SSDs.
🔄 May Require Reformatting for Some Macs
While compatible with macOS, for full Time Machine use or certain Mac workflows, you may need to reformat — a step that might be unfamiliar to some users.
🧰 Bulkier Desktop Form Factor
Because it’s a larger desktop device, it takes up space and needs both USB and an AC power connection — something portable drive buyers might find inconvenient.
📊 Best Use Cases
Ideal for:
✔ Home or office desktops needing reliable, high-capacity backups.
✔ Users wanting automatic scheduled backups and password-protected storage.
✔ Mac users planning to use Time Machine backups.
✔ Media libraries, project archives, and digital hoarders.
Not ideal for:
❌ Frequent on-the-go portability.
❌ Users seeking SSD-level transfer speeds.
❌ Minimalists who prefer tiny, bus-powered drives.
💡 Real-World Performance & Reliability
Many reviewers and users note that the My Book performs quietly and steadily, making it well-suited as a backup drive that stays connected most of the time. Transfer speeds vary depending on file size and system configuration but are generally in line with other external HDDs.
The inclusion of WD Discovery utilities also allows you to connect with cloud or social media accounts, import files, and manage the drive via WD Drive Utilities — a helpful toolkit for desktop storage management.
📏 Final Thoughts
The Western Digital My Book 4TB External Hard Drive stands out as a solid, trustworthy, high-capacity desktop storage solution with useful backup and security features you won’t always find in basic external drives. While it won’t give you SSD speeds or ultra-portable convenience, its massive space, automatic backup tools, and password protection make it a great choice for users who want a serious storage hub for photos, videos, documents, and system backups on Windows or Mac.
If your priority is capacity + protection + ease of use, this WD My Book model is worth considering — especially for long-term storage needs.
