Raoyi USB-C Flash Drive 128GB Silver
Score: 61/100
Vansuny USB Flash Drive 512GB
Score: 79/100Rankings

The Vansuny 512 GB Type-C flash drive delivers near-1 GB/s sequential performance and a rugged zinc-alloy body with dual USB-A/C connectors. Its random-access speeds and occasional USB-C throttling are drawbacks. Ideal for creators moving large media files on the go.

The RAOYI 128 GB USB-C dual thumb drive provides up to 70 MB/s read speed in a slim, keychain-ready aluminum design. It lacks detailed durability data and offers modest write performance. Suitable for users needing portable storage for large files without a heavy build.

Professional coverage of the Raoyi 128 GB flash drive is limited, but the brand's dual USB-A design is praised for its broad compatibility and solid build in related SSD reviews. However, reviewers point out the scarcity of specific performance benchmarks and durability data for this exact model.
Consumers consistently highlight the drive's speed and reliability, especially for large video files, and appreciate its portable, keychain-ready design. The main criticism revolves around missing durability details rather than functional shortcomings.

“Lightning fast for security cam videos”

“Exceeds expectations compared to slower same-spec competitors”



Professional reviewers commend the Vansuny 512GB OTG drive for its near-advertised sequential performance, high AS SSD benchmark score, and robust zinc-alloy construction, but they point out inconsistent USB-C speeds and modest random 4K read rates, and note the lack of coverage from major tech publications.
Everyday users appreciate the fast large-file transfers, especially the ability to move a 4 GB movie to a phone in seconds, and value the plug-and-play experience across multiple platforms, though they report occasional port-speed differences and wish for more information on durability and heat.
