Score: 76/100
Kingston DataTraveler DuoG2 256GB
Score: 64/100Rankings

The SanDisk 128 GB Ultra Dual Drive Luxe combines a premium all-metal body with dual USB-C/USB-A connectors and a swivel mechanism, delivering solid read performance and a keyring-ready design. However, its write speeds are modest, it lacks built-in encryption, and it may heat up under heavy use.

The Kingston DataTraveler DuoG2 256 GB delivers versatile dual-connector functionality and ample storage in a compact plastic body, backed by a five-year warranty, though it lacks encryption and may feel slower than expected.
