Score: 39/100
Samsung BAR Plus 256GB
Score: 84/100Rankings
The Samsung BAR Plus 256 GB flash drive delivers strong read performance and a rugged all-metal design, backed by a five-year warranty. Write speeds are less consistent, and the lack of USB-C may be a drawback for users with newer devices.
The Ultra Dual Drive 128 GB offers a sturdy metal body with both USB-A and USB-C connectors, delivering fast reads and a convenient keyring loop. Lack of native encryption and modest write speeds make it better suited for occasional transfers than heavy-write tasks.
