Products in the top-left offer the best value (high score, low price).
Professional reviewers note that while the drive provides the expected 5400 RPM performance of a USB 3.0 mechanical HDD (80-110 MB/s sustained), the Type-C port does not deliver USB 3.1/3.2 speeds and the lack of firmware support raises durability concerns. The product is positioned as a low-cost, basic storage option with limited long-term reliability.
Everyday users appreciate the drive's light weight, immediate plug-and-play operation, and ability to work with consoles and laptops out of the box. However, many complain about the actual usable capacity being lower than advertised, early failures, non-recognition by devices, and misleading speed claims.
“Lightweight and easy to carry.”
“Works right out of the box with my laptop and PS4.”
“Only 298 GB shows up-why not advertise that?”
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.
