Kingston DataTraveler DuoG2 256GB
Score: 64/100Rankings
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.
The Amazon Basics 256 GB dual-port flash drive extends the same metal, rotating design as the 128 GB model, offering double the storage while maintaining fast read performance. It remains a budget-friendly option for cross-device transfers but still lacks encryption and detailed write-speed data.
