SamData 128GB USB
Score: 49/100Rankings
The SanDisk Ultra 256 GB USB-A flash drive offers solid capacity and fast read performance with built-in encryption, but its modest write speed and lack of an LED indicator 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.
