SamData 128GB USB
Score: 49/100Rankings
The Netac 128 GB USB-3.0 flash drive offers good read performance and a protective swivel cap at a low price, making it suitable for casual users. However, its modest write speed, lack of encryption, and reported reliability issues limit its appeal for power users.
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.
