SamData 128GB USB
Score: 49/100Rankings

SamData's 128 GB USB 2.0 flash drive is a budget-oriented, metal-cased device with an LED indicator and basic OTG compatibility. While it offers decent durability, its slow transfer speeds and lack of security features limit its suitability for high-performance tasks.

The Kingston DataTraveler 100 G3 128 GB offers solid read performance and a convenient sliding cap, but its write speeds and random performance are extremely low, making it best for occasional read-heavy tasks.
