Desktop storage for Windows and Mac users

The Western Digital My Book 4TB desktop external hard drive connects through a USB 3.0 Micro-B port and is formatted exFAT for immediate use with Windows 10+ and macOS 11+. It ships with WD backup software for Windows and works with Apple Time Machine on Mac. A 256-bit AES hardware encryption option protects files with a personal password. The drive is suited for users who want a single, high-capacity volume for photos, videos, music and documents.

Check your host ports and power

Verify that your computer has a free USB-A port for the included SuperSpeed USB-A cable rated at 5Gbps; the drive is backward compatible with USB 2.0 but will run slower. An AC adapter is required, so confirm you have a nearby mains outlet. The drive arrives formatted exFAT; if you use an older operating system or a different file system, you will need to reformat it. No internal drive bay or PCIe slot is involved.

Compact enclosure with hardware encryption

The black enclosure measures 6.73" x 1.93" x 5.47" and weighs 2.21 lbs, fitting on a desk without occupying much space. A USB 3.0 Micro-B connector on the rear accepts the supplied cable, and the separate power brick keeps the unit running. Built-in 256-bit AES hardware encryption works with WD Security software for password protection. WD Discovery software adds drive utilities and cloud import features. The package includes the drive, cable, AC adapter and quick install guide.

Which interface should I use for the fastest transfer speed on this 4 TB model?

Connect the drive via its USB 3.0 Micro-B port with the supplied SuperSpeed USB-A cable to reach the 5 Gbps link speed; the drive also works with USB 2.0 ports at lower speed.
