Overview

The Western Digital My Book WDBACW0015HBK is a desktop-class external hard drive offering 1.5TB of storage through a USB 3.0 interface. Designed to sit on your desk as a dedicated backup or overflow storage solution, it houses a standard 3.5-inch hard disk mechanism inside a compact vertical enclosure. The USB 3.0 connection provides data transfer rates up to 5 Gbps at the interface level — a substantial improvement over USB 2.0 — making initial large file transfers and routine backups considerably faster. Backward compatibility with USB 2.0 ensures the drive will work with older computers, albeit at reduced speeds.

Western Digital bundles the drive with WD SmartWare backup software, which lets you configure automatic, scheduled, or continuous backups of specified folders to the My Book. This makes it a practical choice for users who want a simple, set-and-forget backup solution without investing in NAS hardware or cloud subscriptions. The drive ships pre-formatted in NTFS for immediate use on Windows systems. Because it relies on an external power adapter rather than bus power, the My Book is best suited as a stationary storage hub rather than a travel companion — users needing portability should consider Western Digital's passport-sized alternatives instead.

Included WD SmartWare software simplifies setting up automatic file backups without third-party tools.

👎 Cons

Requires an external AC power adapter, making it less portable and adding cable clutter to your desk.

Frequently Asked Questions

Is this drive USB 3.0 only, or is it backward compatible with USB 2.0?

It connects via USB 3.0 for maximum transfer speed and is fully backward compatible with USB 2.0 ports, though data transfer rates will be slower on USB 2.0.

Does the My Book require an external power supply?

Yes, the My Book desktop series uses an AC power adapter since it houses a full-size 3.5-inch hard drive, unlike portable drives that are bus-powered via USB.

What backup software is included with this drive?

Western Digital includes WD SmartWare automatic backup software, which allows you to set scheduled or continuous backups of selected files and folders.

Is the drive pre-formatted, and for which operating system?

The My Book typically ships formatted in NTFS for Windows. Mac users will need to reformat the drive to HFS+ or exFAT to use it natively with macOS.

Is this a solid-state drive or a traditional hard drive?

This is a traditional spinning hard disk drive (HDD), not an SSD. It provides high capacity at a lower cost per gigabyte but with slower random access speeds than solid-state storage.
