Raoyi USB-C Flash Drive 128GB Silver
Score: 61/100
Zarmst USB-C 4-in-1 Flash Drive 256GB Blue
Score: 69/100Rankings
The ZARMST 256 GB 4-in-1 flash drive offers a versatile multi-connector design and an encryption app, making cross-platform storage convenient. However, its real-world transfer speeds fall short of claims and it can become hot during use. Best suited for users needing occasional backups across devices.
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 ZARMST drive for its versatile 4-in-1 connector layout, compact thumb-drive form factor, and the security-focused app that adds encryption and fingerprint unlocking. However, they criticize the gap between advertised and real-world speeds, heat generation during transfers, case-related compatibility issues, and raise doubts about the true usable capacity and overall build durability.
Everyday users love the convenience of a single drive that works across iPhone, Android and computers, especially the one-click backup app and the ability to move large media files via USB 3.0. Recurring complaints focus on slower-than-expected transfer speeds, the device heating up, incompatibility with phones in cases, and uncertainty about whether the full 256 GB is actually usable.
