Vansuny USB Flash Drive 128GB
Score: 71/100
Marryler USB Flash Drive
Score: 63/100Rankings

The Vansuny 128 GB metal USB drive offers a rugged, waterproof design with a retractable USB-A connector and high claimed speeds. In practice, actual transfer rates are modest and the drive lacks a USB-C interface. It is ideal for outdoor workers and travelers who prioritize durability over peak performance.

The Marryler 230 GB USB 2.0 flash drive offers a high-capacity metal body that is waterproof and includes a keychain for easy portability. Its main trade-off is the slow USB 2.0 interface and limited warranty. Best suited for users who need large storage for occasional backups and value rugged, portable design over speed.

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

Professional reviewers commend the Vansuny 128GB metal drive for its exceptional ruggedness, waterproof UDP packaging, and plug-and-play ease across platforms, positioning it as a solid value for its price. However, they consistently note that real-world read/write speeds fall well short of the lofty 400 MB/s claim and criticize the single USB-A interface as a limitation compared to newer dual-port alternatives.
Everyday users largely praise the drive's durability, waterproof capability, and convenient retractable design, especially for travel and outdoor scenarios. The dominant criticism centers on the over-hyped speed specifications, with many noting actual transfer rates are much lower and that the device must be dried after water exposure before reuse.
