Score: 76/100Rankings
The Kingston DataTraveler Micro Duo 32 GB is a compact metal flash drive featuring dual USB-A and USB-C connectors and fast up-to-100 MB/s read speeds. Its modest 15 MB/s write speed and limited 32 GB capacity may restrict heavy-use scenarios. Ideal for travelers and photographers needing cross-platform convenience.
Lexar's D400 128 GB dual-drive features a metal swivel housing, keyring loop, and built-in 256-bit AES encryption, delivering read speeds up to 130 MB/s. Write performance is slower and limited user reviews make reliability uncertain. Perfect for professionals requiring secure, cross-device file transfers.

Professional reviewers commend the Kingston microDuo 3C for its dual-connector flexibility, solid metal build, and long warranty, noting that the USB 3.1 interface aligns with modern device standards. However, they criticize the modest 15 MB/s write speed and the limited 32 GB capacity, and they call for independent benchmark data to validate the claimed read performance.
Everyday users praise the drive's convenience, especially the ability to plug directly into both USB-A and USB-C ports without adapters, and they like its compact size and decent read speed. Recurring complaints focus on slow write speeds and the limited storage capacity, with some users wishing for more detailed specifications such as weight.
