Raoyi USB-C Flash Drive 128GB Silver
Score: 61/100Rankings
The SanDisk Ultra Dual Drive 256 GB combines USB-A and USB-C connectors in a retractable design, delivering up to 150 MB/s read speeds and a 5-year warranty. It lacks waterproofing, hardware encryption, and detailed write-speed specifications, which may limit its appeal for power users. Best suited for mobile users who need quick cross-platform file transfers and a compact, high-capacity drive.
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.
