High-resolution photos, 4K videos, large projects, and games require significant space. Let’s take a closer look at it.
Appearance
The first thing that catches the eye is the minimalist and stylish design of the device. The body is made of high-quality matte plastic with a glossy diagonal texture, which not only gives it an elegant look but also makes it resistant to fingerprints. Thanks to its compact size (107.2 x 75 x 19.15 mm) and weight of only 210 grams, the drive easily fits into a jacket pocket or laptop bag, making it an ideal companion for travel.

What’s in the box?
Typically, the WD My Passport drive package is standard and includes everything you need to get started:
- The WD My Passport 4TB hard drive itself.
- USB 3.0 cable (compatible with USB 2.0).
- Quick start guide.



Key Features
The main advantage of this model is the combination of large capacity and reliable data protection functionality. 4TB of space allows you to store hundreds of thousands of photos, thousands of hours of music, or dozens of modern games and movies in high quality. The drive comes with proprietary software, which is the control center for your data.


- WD Backup™: An easy-to-set-up utility for automatic scheduled backup of important files.
- WD Security™: Allows you to set a password and activate 256-bit AES hardware encryption. This means your data will be reliably protected from unauthorized access, even if you lose the drive.
- WD Drive Utilities™: A tool for diagnosing the drive’s condition, formatting it, and setting a sleep timer.
Performance and Speed Tests
The WD My Passport is equipped with a USB 3.0 interface. The most interesting part of any drive review is the speed tests. The device was connected to a laptop via a USB 3.0 port to obtain objective data. Testing was performed using two popular utilities: CrystalDiskMark 8.0.4 and HD Tune Pro 5.75.

CrystalDiskMark Test
This test shows the peak sequential read and write speeds of large files. The results demonstrate excellent performance for its class:
- Sequential read speed: 130.95 MB/s
- Sequential write speed: 121.41 MB/s

HD Tune Pro Test
This program allows you to evaluate the speed across the entire surface of the disk. Your test results were extremely high for a portable HDD, indicating excellent performance of this particular instance.
- Minimum speed: 122.3 MB/s
- Maximum speed: 223.7 MB/s
- Average speed: 219.1 MB/s

In practice, speed depends on many factors, including the size of the files being transferred and your computer’s configuration.
Compatibility
The drive is formatted out of the box in the NTFS file system, making it fully compatible with Windows 8.1 and Windows 10/11 operating systems. For use with macOS, it needs to be reformatted to HFS+ or APFS, which is easily done using the standard “Disk Utility”. After formatting, it will work perfectly with Time Machine for backup.
Conclusions
Western Digital My Passport 4TB is an excellent choice for those looking for reliable, capacious, and portable storage. It is ideal for students, photographers, travelers, and ordinary users who need to expand their laptop’s memory or create a reliable archive of their data. In summary, the WD My Passport 4TB is a balanced and time-tested solution that offers an excellent combination of price, volume, and reliability.
