WD My Passport Ultra 6TB Review: A Quiet Giant Built for Bulk Storage

Portable hard drives are often seen as the workhorses of the tech world-rarely flashy, but incredibly dependable. When Western Digital launched the My Passport Ultra 6TB, I was intrigued. A 6TB portable HDD in a compact 2.5-inch form factor? That's a significant leap from the 5TB ceiling we've had for years.

So I decided to put it to the test-both in real-world file transfers and benchmarking-and here's my complete, hands-on take.

First Impressions: Subtle Design, Built to Travel

The drive arrives in typical WD fashion-clean packaging with the essentials inside: the drive itself, a USB-C to USB-C cable, a USB-C to USB-A adapter, and a quick install guide. There's no carrying pouch, which would've been a nice touch, but the build feels robust. The top half is a sleek metallic blue, while the base is matte black plastic-simple, professional, and solid enough for travel or daily desk duty.

What immediately stood out, though, was how quiet the drive is. I had to shut off my fan and close the windows to even hear the platters spin.

Real-World Usage: How Fast Is It Really?

To simulate my typical workflow, I transferred 62GB of mixed media files from my laptop to the drive. It finished in under 10 minutes, maintaining a stable transfer rate of 110MB/s according to Windows. That's actually faster than I expected from a mechanical HDD, and speaks volumes about the consistency of the controller and the bundled cable quality.

The included USB-C to USB-C cable supports 5Gbps speeds and feels much more premium than the usual generic cords bundled with drives. I didn't encounter any disconnects or speed drops throughout the process.

Benchmarking: CrystalDiskMark Results

I ran CrystalDiskMark using three different file sizes to evaluate both peak and sustained performance:

With 1GiB Test File:

• Sequential Read: 127.99 MB/s

• Sequential Write: 115.07 MB/s

• Random 4K Read: 0.36 MB/s

• Random 4K Write: 12.97 MB/s

With 8GiB Test File:

• Sequential Read: 124.91 MB/s

• Sequential Write: 114.69 MB/s

• Random 4K Read: 0.36 MB/s

• Random 4K Write: 13.01 MB/s

With 32MiB Test File:

• Sequential Read: 392.23 MB/s (brief burst speed likely due to system or drive cache; not sustained)

• Sequential Write: 114.61 MB/s

• Random 4K Read: 0.36 MB/s

• Random 4K Write: 13.01 MB/s

As expected, sequential performance is strong and consistent-ideal for large file transfers, backups, or media libraries. Random 4K reads and writes, which simulate OS-level tasks, are quite low.

This isn't a surprise-HDDs just aren't built for launching apps or handling small frequent reads/writes like SSDs.

Internal SSD vs External HDD

For perspective, I compared these results with my internal NVMe SSD on the ROG Zephyrus G14, also using a 1GiB test:

Laptop Internal SSD (1GiB Test File):

• Sequential Read: 5006.54 MB/s

• Sequential Write: 2607.03 MB/s

• Random 4K Read: 49.15 MB/s

• Random 4K Write: 113.40 MB/s

Compared to the WD My Passport Ultra:

• Sequential Read: 127.99 MB/s
  

• Sequential Write: 115.07 MB/s
  

• Random 4K Read: 0.36 MB/s
  

• Random 4K Write: 12.97 MB/s

This comparison confirms what we already know: HDDs can't compete with SSDs on speed. But they're not meant to. The WD My Passport Ultra is built for reliable, cost-effective, high-capacity storage, not real-time performance.

Software and Utilities: More Useful Than Expected

WD includes powerful software tools that enhance the value of the drive:

• Acronis True Image for Western Digital: This isn't just a backup tool. It supports scheduled backups, file recovery, full disk imaging, and even drive cloning-perfect for system migrations or disaster recovery planning.

• WD Drive Utilities: Here's where you can diagnose your drive's health, run quick or full sector scans, erase data securely, toggle the LED on/off, and even set a sleep timer to save energy when idle. It's genuinely helpful for long-term maintenance.

Both tools are easy to install, lightweight, and well-integrated with the drive.

Security: Password-Protected Peace of Mind

The drive supports 256-bit AES hardware encryption, which you can enable using WD Security. Once set, the drive remains locked until the password is entered.

There's also an optional password hint feature, and you'll need the software installed to access encrypted content.

It's an excellent security layer if you carry sensitive files-client work, legal documents, or personal backups.

Final Verdict: Is It Worth It?

If you're looking for the fastest external drive, this isn't it-and it's not pretending to be. But if you need a massive amount of portable storage, quiet operation, and reliable performance for backups or archiving, the WD My Passport Ultra 6TB is a great choice.

At ₹16,899, it's significantly more affordable than SSDs at equivalent capacities. With good bundled software, encryption, and solid real-world speeds for an HDD, this drive justifies its price well.
