Products in the top-left offer the best value (high score, low price).

Reviewers commend its capacity, USB 3.0 performance, and encryption, while noting the lack of a metal chassis and rugged features.
Users appreciate its reliability and value, but frequently mention the need to reformat for Mac and the plastic build quality.

“I had to learn how to format via Disk Utility for use with MacBooks, but it works well now and does what it is supposed to do: sit there and blink.”

“Works perfectly with my PS4 and laptop.”

“Very thin and light - fits in my pocket.”



WD My Passport is better for users who value bundled software and brand trust, while Tianken wins on portability and cost.

Professional reviewers would categorize the Tianken drive as a budget-tier external HDD, praising its low cost, thin profile and long warranty, but criticizing its lack of SSD performance, plastic construction and absence of security features, making it suitable for casual storage rather than demanding professional workflows.
Everyday users generally appreciate the drive's portability, ease of use and price, especially for gaming consoles and photo backups, while recurring frustrations revolve around the reduced usable capacity, the need to reformat for Mac, modest transfer speeds and concerns over the cheap plastic housing.
